Korean Journal of Medicinal Crop Science, volume 6, issue 4, 1998, Pages 239~244
This experiment was to determine the effects of soil pH on crude components and aromatic constituents of Codonopsis lanceolata. Vine length of Codonopsis lanceolata grown at soil pH of 6.5 was longer(299cm) compared to that grown under other soil pHs. Fresh root weight increased at soil pH of 5.5 and 6.5, showing 17.9 and 15.6g per plant, respectively. Contents of crude components such as protein, fat, fiber, and ash decreased as soil became alkalized and crude ash content ranged from 2.99% to 3.85 %, showing a similar response to soil pH. Forty-eight volatile aromatic compounds in the root of Codonopsis lanceolata were identified by GC/MS. Major aromatic compounds were 1-hexanol, cis-3-hexanol, and trans-2-hexanol. In particular, trans-2-hexanol was highest in soil pH of 6.5, attaining the 156.87% area. Essential oil content was also highest at soil pH of 6.5 with 0.007%. As a result, it was considered that the soil pH of 6.5 was most effective for the improvement of essential oil and aromatic constituents in the roots of Condonopsis lanceolata Trautv.

This research was carried out to investigate the effective methods of browning inhibition on Paeonia lactiflra Pall during hot air dehydratin. After drying for 36 hrs without pretreatment and with briquet fumigation moisture contents of Paeonia lactiflora Pall. was 16.0% and 16.2%, respectively, while with acidic solution, sulfite salt solution and blanching it was lower of 13.5, 12.9 and 14.8%, respectively. Using freeze drying moisture content was highest of 18.8%. The Hunter values of dried Paeonia lactiflora Pall., L, a, band
showed that non-treatment had the most browning with 61.60, 1.89, 10.20 and 39.78, respectively, while briquet fumigation and sulfite salt solution were excellent in reducing browning. During freeze drying browning didn't occur. Paeoniflorin content was 2.41 and 2.51 %, respectively, in briquet fumigation and sulfite salt solution and was the highest (2.70%) in freeze drying. The content of
, was 0.63% both in briquet fumigation and sulfite salts. It was 0.15% and 0.17% higher than nontreatment and freeze drying. The most effective pretreatment to inhibit browning of Paeonia lactiflora Pall. was soaking in sulfite salt solution
considering many things such as manpower, economical efficiency, drying time, commodity, etc. but safety should be evaluated to treat sulfite salts solution on peony roots.

Choi, Seong-Kyu ;
Korean Journal of Medicinal Crop Science, volume 6, issue 4, 1998, Pages 251~257
This experiment was carried out to establish cutting propagation method of dendropanax morbifera
. at Wando in Chonnam, native area. The hardwood cutting and the greenwood cutting were able to be used as propagation method, but callus formation and rooting ratio in the greenwood cutting were higher than in hardwood cutting. The optimum cutting time was February to middle of March in hardwood cutting and July to August in greenwood cutting. The earthen-ball cutting method was better than normal cutting method in callus formation and rooting ratio. The rooting in different bed soils was the best at sand-loam soil. The application of IBA 100ppm promoted rooting.

This study was conducted to establish mass propagation system from seeds of Lavandula angustiolia Mill. Only 4% of dry seeds were germinated when they were incubated in
. Germination rate of stratified seeds for 9 weeks was 15% higher in light than darkness. Soaking with 1000mg/l of
was helpful to overcome the effect of darkness. The optimal temperature for germination was
for the seeds that were treated with
, solution. For the improvement of germination rates, pretreatment of
at 500-2000mg/l showed about 75% of germination, and in the combination treatment of
, and BA, germination rate increased by about 10% in the treatment of 1000mg/l
BA compared with the 1000mg/l
treatment. Cold stratification treatment was very effective for seed germination, and over 70% of seeds were germinated when they were incubated in
for 9-12 weeks. In addition, there was synergic effect on the seed germination subject to stratification and 1000mg/l
, treatment for 6 months. In the mixture of vermiculite: peatmoss (1 : 1, v/v), emergence rate was 6.7% in control and 65% in 1000mg/l

The curd yogurt was prepared from skim milk powder added with the juice, puree and powder, respectively, of the roots of Platycodon grandiflorum (Jacq.) A.DC. Twelve hours were proved to be best for fermentation of the curd yogurt, which showed 4.1 in pH and 1.15% in titratable acidity. Quality of the curd yogurt in sensory evaluation was best when 2 % of juice, 1 % of puree and 1 % of powder were added to the skim milk powder, respectively. When curd yogurt was kept at
for 9 days, pH decreased, while titratable acidity increased. The viscosity was highest with addition of puree 1%. After fermentation, number of viable cell was
in juice 2%,
in puree 1% and
in powder 1%. When curd yogurt was kept at
for 9 days, its keeping quality (pH, titratable acidity, viscosity and number of viable cells) were good.

Korean Journal of Medicinal Crop Science, volume 6, issue 4, 1998, Pages 271~276
This experiment was carried out to determine the effects of topping time and fertilizer split application on the growth and root yield of Scutellaria baicalensis G. In case of stem cutting at 25cm above the soil surface early in July and middle in August, plant height was reduced by 37cm compared with nontreatment, but stem diameter, the number of branch per plant and the growth of root increased. Topping treatment twice produced the highest dry root yield (182kg/10a) of all, 15% higher than nontreatment. When nitrogen and potassium were applied by the basal dressing with 60% and by the top dressing early in July and middle in August with 20% in each time, the growth of plant (both top and root) increased. The dry root yield per 10a in top dressing twice was 12% higher than once.

Paik, Su-Bong ; Chung, Il-Min ; Doh, Eun-Soo ;
Korean Journal of Medicinal Crop Science, volume 6, issue 4, 1998, Pages 277~285
Antifungal activity on major seedborne diasease of crops was screened by the treatment of the extracts from 50 medicinal plants in vitro and in vivo. The extracts of garlic and taxus, Rheum undulatum, Achiranthes japonica, Glycyrrhiza uralensis, Oenothera lamar kiana treated with the blotting filter paper and water agar methods inhibited the growth of Pyricularia oryzae, Alternaria sesamicola, Colletotrichum gloeosporioides, and Alternaria brassicicola among the tested plants. Antifungal activities on infected seeds by soaking methods were shown even at the dilution of the extracts by 10 times. The activity was the highest in soaking seeds at
for 24 hours. The effect of plant extract on seed germination was not significant as compared with untreated seed. However, early growth of seedling was increased by the treatment of extracts. The extract of taxus slightly inhibited the seed germination of radish and chinese cabbage but those of Achirunthes japonica, Glycyrrhiza uralensis and Oenthfera lamarkiana showed severe damage on the seed germination and early growth of seedling.

Korean Journal of Medicinal Crop Science, volume 6, issue 4, 1998, Pages 286~293
This study was carried out to find the effects of seed tuber position and number of nodes on growth of Saururus chinensis Baill. at experimental field of Chungbuk Provincial Rural Development Administration from 1996 to 1997. Seed tubers were divided into upper, middle and lower parts, and they were prepared to 1-, 2-, 3-node cuttings in each. Percentage of sprouting in planting of middle part was highest of 92%, and the percent increased by increasing the number of nodes. Growth of shoot and root tuber was the most favorable with planting of 3-node cuttings of middle part, and leaf area index (LAI) was highest of 3.10 in the same treatment. Dry matter weight and percentage of root tuber were highest of
and 28 % with planting of 3-node cuttings of middle part. Yield of dry leaf and root tuber were highest of 272kg/10a and 821kg/10a with planting of 3-node cuttings of middle part.
Effects of Explants and Growth Regulators on Direct Somatic Embryogenesis in Liquid Culture of Scrophularia buergeriana
Song, Ji-Sook ; Lim, Wan-Sang ; Chae, Young-Am ;
Korean Journal of Medicinal Crop Science, volume 6, issue 4, 1998, Pages 294~298
The factors affecting direct somatic embryogenesis from different parts of explant in liquid culture of Scrophularia buergeriana were investigated. Direct somatic embryogenesis was dependent on the explant tissues and stem was the most efficient explant. Rapid shoot development occurred on stem after 3-week culture but roots were not developed yet. Plantlets were not formed through somatic embryogenesis after 3-week culture of petiole. Though direct somatic embryo was not observed from leaf segment culture for 3 weeks, normal plantlets were developed after 8-week culture. BA played the main role for somatic embryogenesis in liquid culture and adding of either IAA or NAA caused rather adverse effects. Culture of stem segments in MS liquid medium with BA at 0.5 mg/ l or 0.1 mg/ l was proved to be the most efficient method for producing plantlets through direct somatic embryos.

This experiment was conducted to determine the essential oil content and the aromatic constituents in the leaves of Saururus chinensis Baill, Angelica dahurica Fischer and Cnidium officinale Makino. Volatile aromatic compounds in three aromatic medicinal plants were extracted with steam distillation extraction method and identified by GC/MS. Major aromatic compounds in Saururus chinensis Baill were 1,6-octadien-3-ol, 1, 3-benzodioxole, myristicin,
and patchouene. Major aromatic compounds in Angelica dahurica Fischer were terpinolene, 3-carene,
, butylated hydroxy toluene, caryophyllene oxide, piperonal, and in Cnidium officinale Makino were aristolene, benzocycloheptene, ylangene, valencene,
, satene, and menthofuran. Essential oil content was highest in Saururus chinensis plant.

Glucosidic bond at the
position of the sapogenins was hydrolyzed easily in the lower pH, higher temperature and longer time to give prosapogenins and sugars. The glucosidic bond of saponin at the
, which is secondary carbon, was relatively stable due to the low electron density of -0.2. But the bond of saponin at the
position, which is tertiary carbon with the relatively high electron density of -0.3, was liable to be hydrolyzed even in weak acidic solution by the increase of heating time. On the other hand, fresh and white ginseng contained 4.12 mg/g, 13.05 mg/g of citric acid, 0.68 mg/g, 2.18 mg/g of malonic acid, 1.13 mg/g, 3.68 mg/g of oxalic acid, 2.68 mg/g, 8.62 mg/g of malic acid and 0.13 mg/g, 0.46 mg/g of succinic acid, respectively. Ginseng saponins were very stable in ginseng extract neutralized with sodium carbonate or sodium bicarbonate corresponding to the equivalent amount of the total organic acid in the ginseng.

Chung, Il-Min ; Kim, Kwang-Ho ; Ahn, Joung-Kuk ;
Korean Journal of Medicinal Crop Science, volume 6, issue 4, 1998, Pages 311~322
Sixty medicinal and food plants native to Korea were mainly selected with old traditional habit and antioxidant activity was investigated. The 80% EtOH extracts of sixty medicinal and food plants were screened for antioxidant activity. Antioxidant activity was measured by the TBA (Thiobarbituric acid), DPPH (1, 1-Diphenyl-2-picrylhydrazyl), SOD (superoxide dismutase) which was evaluated by the nitro blue tetrazolium(NBT) reduction method. Among sixty plants, black Glycine max(87. 3%) and Solanum nigrum (80.6%) exhibited the highest antioxidant activity by TBA and DPPH methods, respectively. Also, 10 species extracts including black Glycine max showed the high activity value in these two methods. The SOD characteristics on black Glycine max seed extracts which showed the highest SOD activity (53.5%) exhibited four major SODs; two Cu/ZnSODs and two FeSODs. However, Adenophaora vertidllata which showed lowest SOD value (10.4%) had only Cu/Zn SOD. No varietal differences in the high SOD value were detected in the Cu/Zn SOD isozyme patterns.

Korean Journal of Medicinal Crop Science, volume 6, issue 4, 1998, Pages 323~327
The contents of saikosaponin a, c and d in the root of somaclones and wild plants of B. falcatum L. were determined. The saikosaponin contents of wild plants collected from Chongson-gun, Kangwon Province and Yongdok-gun, Kyongbuk Province were higher than those of the somaclones derived from 3-month and 2-year aged calli. The mean values of saikosaponin content in 2 year-old somaclones derived from the callus cultured three months were higher than those in 1 year-old somaclones from 2-year aged callus. Variation of saikosaponin content depending on the culture periods was not found. Four plants among 1-year old somaclones showed saikosaponin content twice as much as wild plants had. This result implies the possible use of somaclonal variation for crop improvement.
