The object of this study was to obtain single oral dose toxicity of Arisaema Rhizome (Arisaema amurense f. serratum (Nakai) Kitag) aqueous extracts. Arisaema Rhizome (Chunnamsong in Korean) is one of the most important folk remedy plants used in Asia. In the study, a 28-day rat oral gavage study has been conducted with the extracts from Arisaema Rhizome at dose of 1,250, 2,500 and 5,000 ㎎/㎏/day. The following endpoints were evaluated: clinical observations, body weight, gross and microscopic pathology, clinical chemistry, and hematology. Based on the analysis of these endpoints, it was estimated that NOEL (no observed effect level) for male rats and NOAEL (no observed adverse effect level) for female rats are 5000 ㎎/㎏/day of the water-extracts from Arisaema Rhizome.

Momordica charantia L. is a valuable food and medicinal plant of the gourd family (Cucurbitaceae) that is cultivated in tropical and subtropical regions of the world. Physicochemical properties of M. charantia based on cultivars, parts and growing stage were investigated. Crude protein contents of leaf were 27.5%, 26.9%, and 23.6% in native leaf (NL), cv. Erabu leaf (EL), and cv. Dragon leaf (DL), respectively. In particular, the crude protein content was the highest in leaves. The crude fat content was in the order of developmental stage 1 of cv. Erabu fruit (EF1) and developmental stage 1 of native fruit (NF1) with values of 4.0%, and 3.9%, respectively. There was also high amount of crude fiber in stem of all three cultivars. The crude ash content was in the order of cv. Erabu leaf, cv. Dragon leaf, and developmental stage 3 of native fruit (NF3) with values of 23.2%, 17.4%, and 13.6%, respectively. The major minerals found in M. charantia were K, Ca, and Mg. The potassium contents of developmental stage 3 of native fruit (NF3), developmental stage 3 of cv. Dragon fruit (DF3), cv. Dragon stem (DS), and developmental stage 2 of native fruit (NF2) were 498.37, 339.21, 314.30, and 307.34 ㎎ /100g, respectively, while the calcium contents were decreased of EL, DL, and NL with values of 513.45, 371.69, and 209.43 ㎎/100g, respectively. The calcium content was higher in leaves and stems than fruits. On the otherhand, the highest magnesium content was measured in EL (69.92 ㎎/100g). The highest contents of chlorophyll a, chlorophyll b, and total chlorophyll were found in NL (442.9 ㎎/100g dw), EL (759.6 ㎎/100g dw), and EL (1164.9 ㎎/100g dw), respectively. The vitamin C contents from developmental stage 2 of cv. Erabu fruit (EF2), NF3, developmental stage 3 of cv. Erabu on fruit (EF3), and NF2 were found with values of 2849.9, 2330.5, 1985.1, and 1844.5 ㎎/㎏, respectively, and found to be higher in Korean cultivar and Erabu fruit than in Dragon. The charantin contents of leaf were higher than the fruit found to be 547.71, 506.04 and 395.62 ㎍/g dw in DL, EL and EF2, respectively. According to the results, mineral contents, total chlorophyll and charantin contents of M. charantia were higher in the leaves (EL and DL) than the fruits. And, vitamin C content was the highest in the fruit (EF2 and EF3). Therefore, much more research needs to be undertaken to use of the leaves as well as fruits. The data showed that M. charantia can be considered a good source of nutrient for application in food system.

There has been little research on the harvesting time-dependent changes in the antioxidant activities of new varieties of highland cultures of Gomchwi (Ligularia fischeri) crossed with Turcs (Ligularia fischeri (Ledeb.)) and Nakai (Ligularia fischeri var. spiciformis), namely Sammany (S), Gommany (G) and Damogy (D). This study was conducted to assess the effect of different harvesting times on nutritional and health-related properties such as total phenolic contents, flavonoids, DPPH (1,1-diphenyl-2-picrylhydrasyl) free radical scavenging activities and reducing power. From these harvests, extracts were prepared using methanol. Total phenolic content in Jul 14-G (Gommany harvested on July 14, 0.172 ㎎·GAE/ml) was higher than that in other products harvested after the same period (S, 0.154; D, 0.141 ㎎·GAE/ml). Flavonoid content was higher in Jul 3-G (0.114 ㎎·QE/ml), compared to Jul 3-S (0.113 ㎎·QE/ml) and Jul 14-D (0.089 ㎎·QE/ml). Antioxidant activities were higher in samples harvested after June 12 in all cases. On July 14, the highest DPPH free radical scavenging activities among all harvest dates were seen (92.875~94.595%). The reducing power was also dependent on harvest day (Abs 0.5~0.6 on July 14), showing a pattern similar to that of DPPH free radical-scavenging activities. Antioxidant activity and harvesting times seem to correlate with total polyphenol and flavonoid contents.

Juniperus chinensis (Cupressaceae) is a valuable woody plant resource, but this rare plant is only distributed in restricted regions in Korea. In this study, we surveyed the geographic distribution regions, variation of sex ratio and the dynamics of natural populations of J. chinensis. in order to establish conservation strategies for the sustainable conservation of this important resource tree. The 17 natural populations of J. chinensis are restrictively distributed in the shore cliffs of (1) Ulleungdo island, (2) Gyeongju-si to Gangneung-si of the eastern coast, the riverside cliff along (3) Donggang-river of Jungsun-gun and Pyeongchang-gun and (4) branch of Nakdonggang-river in Uiseong-gun. The populations in Ulleungdo island showed continuous population distribution of over 200 individuals, but populations in other regions had discontinuous population distribution of under 200. The population of J. chinensis surveyed in Korea was estimated in ca. 3,200 individuals. The sex ratio (male/female) among populations of J. chinensis was diverse with variation from 0.46~1.67 range, but showed no significance. The sex ratio of the total individuals by species level was 0.74, and the percentage of female tree was significantly higher than the male. The results of dynamics analysis within population among regions showed that seedlings and saplings of J. chinensis in three regions surveyed were continuously regenerating. The distribution of DBH class showed a stable population structure of inverse J shape graph, but fragmentation and decrease in populations because of invading broad-leaved shrubs and trees from the surroundings were concerned. Further studies, and in situ and ex situ conservation strategies for the sustainable conservation on natural populations of this rare resources woody plant, J. chinensis in Korea are recommended.

Lonicera caerulea var. edulis is a rare species found in some alpine region of Korea. Genetic variation in L. caerulea var. edulis has been investigated by examining 161 individuals from six natural populations: Mt. Seorak 1, Mt. Seorak 2, Mt. Jeombong, Mt. Bangtae, Mt. Gyebang, Mt. Halla. The mean genetic diversity for all the six populations was 0.25 (S.I.). The highest genetic diversity was found in Mt. Seorak (S.I.=0.3158) and the lowest was in Mt. Gyebang (S.I.=0.1047). Comparatively low level of genetic diversity was observed (Ae=1.25, P= 64.6%, S.I.=0.25), which is a typical pattern for rare tree species. AMOVA showed exceptionally large proportion of genetic variations both for among populations (34.69%) and within populations (65.31%). Excluding Mt. Gyebang, the genetic variation among and within population was 18.71% and 81.29% respectively. The UPGMA dendrogram based on genetic distance is not suitable for geographic relationship. Genetic distance of Mt. Gyebang was most distant from the other populations. Excluding Mt. Gyebang, the genetic identities among the five populations were 0.95 to 0.97, which is very high similarity level of genetic identity. This low level of genetic variations and the lack of site in nature indicates that Lonicera caerulea var. edulis demanded a serious conservation.

Scutellaria baicalensis Georgi (SJ) is a perennial plant and its root has been used in oriental traditional medicine for treatment of fever, inflammation, diarrhea and anticancer effect, etc. In this study, plant tissue culture system for SJ was developed. Stem piece of younger plant was optimum explant for callus induction and growth on MS medium supplemented with NAA 1.0 ㎎/L plus BA 0.5 ㎎/L. Plantlet regeneration through callus culture was well on MS medium containing NAA 1.0 mg/L. SJ has been known biologically active substances such as baicalin, baiclein, and wogonin. This study was carried out to examine the effect of plant growth regulators for production of baicalin, baicalein, and wogonin through callus culture. The HPLC pattern of callus extract was identical to that of standard solution, it shows that the callus produced by tissue culture has the same flavonoids composition of SJ. Baicalin, baicalein, and wogonin production was 471.5~52.8 ㎍/g, 137.6~4.0 ㎍/g, and 16.6~1.3 ㎍/g, respectively, on MS media with nine different plant growth regulator combinations. This may indicate that plant tissue culture of SJ possible to produce the biologically active substances effectively

Germination properties, leachate electrical conductivity (EC), and inorganic compound leaching were analyzed to ascertain the storage ability and change of physiological characteristics during storage of Hippophae rhamnoides seeds. Seeds were placed in an incubator at 25℃ and sown in different soil media (sand, vermiculite and horticultural substrate) after being stored for 6, 18 and 30 months at 2℃. All germination properties decreased in accordance to an increase of the seed storage period. Compared with the seed storage for 18 months, germination percentage (GP), germination performance index (GPI), and germination value (GV) of seeds stored for 30 months decreased by more than 50%. When the seeds were sown in different soil media in a greenhouse, those germination properties were similar to the seeds germinated in an incubator, and mean germination time, GPI and GV had a significant difference except GP among soil media. EC and inorganic ion concentration had a strong positive correlation with the seed storage period, but the ratios of inorganic ions from stored seeds revealed that K
were inversely correlated with the storage period.

This study investigated the effect of planting density on growth and yield of elephant garlic. Three planting densities of 20 × 20, 20 × 15, and 20 × 10 ㎝ were tested with the furrow width fixed at 120 ㎝ for the evaluation of elephant galic growth and yield. The average date of emergence was middle and late November, requiring about 30 days for the all emergence. For the flowering, 221 days after sowing were required in all the treatments. Plant height and leaf growth were not significantly different according to the planting density. Flower stalk was shorter when planting density was narrow. The L/D ratio was decreased to form oval shape when planting density was narrow. The yield of elephant garlic was 1,811 ㎏ /10a in planting density 20 × 20 ㎝, 2,375 ㎏/10a in 20 × 15 ㎝, and 2,838 ㎏/10a in 20 × 10 ㎝ plot. The marketable garlic ratio was highest as 1,593 ㎏/10a in planting density of 20 × 15 ㎝.
