Chicory roots were roasted under various conditions. For roasted chicory roots, chemical compositions were investigated to develop new food materials from Korean chicory roots. Raw chicory root consists of 76.34% of moisture, 20.50% of nitrogen free extract, 1.03% of crude protein, 0.13% of crude fat, 1.02% of crude fiber and 0.98% of crude ash. Dried chicory root contains 3.44% of moisture, 79.52% of nitrogen free extract, 5.63% crude protein, 5.51% of crude fiber, 4.85% of crude ash and 1.05% of crude fat. Moisture content of chicory root decreased gradually with the increase of roasting time at
, while decreased significantly by roasting at
and dropped below 1.0% in the 40 min. of roasting at all roasting temperatures tested. Crude protein content decreased with an increase of roasting temperature and time. Crude protein content decreased by 1.60% after 40 min of roasting at
. The amount of reducing sugar decreased gradually as roasting time at
increased. It reduced remarkably roasting at
. Crude protein and reducing sugars seemed to be consumed as substrate for maillard reaction.
of Mg were contained in chicory root and theirs contents were not changed in different roasting conditions. Thirteen fatty acids were isolated and identified from chicory root and it among them linoleic, linolenic, palmitic and oleic acids were the major components. Saturated fatty acid content was 22.81% and unsaturated fatty acid content was 77.19% and fatty acid composition was not changed by roasting under different conditions.

A field experiment was conducted to evaluate effect by split-application of slow-release fertilizer on the tea plant. The yield of the 2nd harvested tea leaves was not different to the slow-release fertilizer of two time split manuring had been doing Sep. or Mar. compared with the traditional manuring had been doing four time split manuring, but that of the slow-release fertilizer to one time split manuring in Sep. had decreased
. In case of the 2nd harvested leave, the contents of chemical components related to quality such as total nitrogen, total amino acid were somewhat higher in the slow-release fertilizer (two time split manuring) than in the traditional manuring, but those of tannin, and caffeine were low, and those of chlorophyll, vitamin C, free sugar and theanine were not different to out of treatments. In scoring test, appearance and quality of green tea were more excellence in the two time split manuring compared with one time split manuring of slow-release fertilizer and with the traditional manuring (four time split manuring). Therefore, I thought that use of slow-release fertilizer be increased yield and quality of tea leaves, and improved efficiency nature of nitrogen, phosphate and potassium out of soil fertilizer components.

This study was carried out to compare the biological activities of Epjmedium koreanum Nakai grown wild in Korea and China. The antioxidative effect of E. koreanum Nakai-extracts grown wild in Gangwondo was 78%, which was higher than that in China as 71%. The inhibition ratio of growing cancer cells was estimated as 89, 91 and 86% for human liver, lung and breast cancer cell lines, respectively in adding 0.1 g/l of ethanol extracts of E. koreanum grown in Korea. The hepatoprotective effect and Angiotensin Converting Enzyme (ACE) inhibiting effect of Korean one were also observed as 124 and 87%, respectively, which were also higher than those produced in China. There was not much difference between Korean and Chinese one in inhibiting
activities in all ranges of supplement. It was proved that most effective extraction solvent was mixed type as water and ethanol (1:1, v/v) to have higher biological activities from both Korean and Chinese ones.

This experiment was conducted to establish the standard of quality evaluation in peony root (Paeonia lactiflora Pall.) cultivated in Korea. The contents of extract and changes of extract pH in peony root with different root ages, cultivars and drying method were investigated. The contents of extract and changes of extract pH in peony root with the removed and the unremoved cork layer showed no difference among different root ages. On the other hand, the contents of extract in the root with the unremoved cork layer which was two- to four-year-old, were higher by 3.7 to 9.2% than those in the root with removed cork layer. This suggests that cork layer might be a good source of extracts. The contents of extract in root of Youngchonjakyak in both the removed and the unremoved cork layer were 36% and 30%, respectively and were higher than of Euisungjakyak and Jomjakyak, but the extract pH was not significantly different among three cultivars which were four-year-old. It showed that the contents of extract and the changes of extract pH in peony root with the removed and the unremoved cork layer of Euisungjakyak, which being four-year-old, showed clear difference at various drying methods. Among the different drying methods, it showed that the contents of extract of that with unremoved cork layer in the room temperature drying method was 32.8%, and that of root with the removed cork layer in the
hot water treatment drying method was 28.1% which were the highest values, respectively. The pH of extract in freeze drying was the highest (about 5.1), and the
hot water treatment drying showed the lowest (about 3.7).

This experiment was carried out to investigate the effects of
and cold stratification as presown treatments on seed germination, seedling emergence and final survival rate of Acanthopanax senticosus Maxim. Seeds collected 145 days after-ripening period followed by 10 days of cold stratification was effective in promoting germination. Dehisced seeds treated with 500 ppm of
for 3 days was also effective in promoting germination. However, seedling emergence rate remained low in both treatment. Seedling emergence rate was higher for seeds germinated in Heungnong-Bio and Klasman-Bio than in vermiculite, perlite, vermiculite-perlite mixture, or sand. After 40 days of cold stratification, seedling emergence was significantly higher in the 500 ppm
treatment than nontreatment for both dehisced and non-dehisced seeds. However, for dehisced seeds,
treatment before sowing resulted in decreased final seedling survival rate.

There were so many Asparagus cochinchinensis (Lour.) Merr. in the past in Korea. Now a day, it is under diminishing circumstance because of over exploitation for pharmacy materials. The amount of domestic market demand of it was imported. The autochthonous planting areas were mainly surveyed along coastal region and island. Autochthonous A. cochinchinensis was mainly distributed in sea shore below 1km from sea and founded 26 regions among 45 surveyed regions. Northern and eastern limited distribution of A. cochinchinensis was
in the west coast and
in the south coast of Korean peninsula, respectively. But it was not founded in the east coastal region. Dominant vegetation of surveyed area was pine with shrub. The number of tuberous roots of A. cochinchinensis growing in good light penetration was more than growing in bad light penetration.

This experiment was carried out to investigation the growth differentiation between direct sowing and transplanting on P. ginseng cultivated on field and underwood. The results were as follows: In direct sowing treatment, emergence rate of P. ginseng cultivated on field and under conifer forest was above 80%, but it was only 40% at cultivated under broad-leaved forest. And survival rate was directly diminished about 10% every year. In transplanting treatment, survival rate was also diminished every year, it was slighter than that of direct sowing treatment. The growth amount of P. ginseng cultivated underwood was poor, compared to field culture, but there was no significant between conifer forest and broad-leaved forest. In transplanting treatment of 1 to 6 year-root seedling, survival rate of P. ginseng cultivated underwood was equal or slightly good compared to that of cultivated on field. Among seedling age, survival rate of elder seedling was lower than that of younger seedling. In P. ginseng cultivated underwood, the annual growth increment of 1 and 2 year-root seedling increased slowly and continually, whereas, that of 3 to 6 year-root seedling stopped or decreased slightly.

To investigate effect of fruits of Hovenia dulcis Thunb. on learning ability of ethanol-induced rats, we divided rats into 3 groups; normal, control and sample groups. Control group administered ethanol at a dose 3 g/kg bw. (25 v/v %), while sample group administered the water extract of fruits of Hovenia dulcis Thunb. 30 min. before treating same dose of ethanol as control group orally. All groups were subjected to trials of straight channel on the 1st day and to those of multiple T-maze during the following 3 days. The time required in normal group for the straight channel of the 2nd and the 3rd trials was significantly shorter than that of the 1st, while control group showed no significance. In the time required for the multiple T-maze trials of control group, there were no significance. But in the straight channel or multiple T-maze trials, the sample group showed significant decrease in the time required against control group, and also showed significant decrease in the number of selecting errors.

Angiotensin converting enzyme(ACE) belongs to the class of zinc protease and plays an important role in the regulation of blood pressure. In this experiment, we investigated the inhibitory activities of ninety four plant extracts on ACE. The extracts were prepared by water and refluxing with 70% and 100% methanol. Among the extracts, two plant extracts such as Cassia tora, Persicaria cochinchinensis Kitagawa showed more than 60% inhibitory activities, and Foeniculum vulgare Gaertner, Scutellaria baicalensis Georgl, Caragana sinica (Buchoz) Rehder, Inula britannica var. chinensis showed
inhibitory activities. Twenty eight plant extracts such as Hemerocallis fulva L, Camptotheca acuminata Decne, Inula britannica var. chinensis, Xanthium strumarium, Polygonatum odoratum, Phellodendron amurense Rupr, Coix lachryma-jobi var. mayuen, Prunus ansu, Hibiscus mutabilis L, Thchosanthes kirilowii, Helianthus annuus, Juglans sinensis showed
Inhibitory activities. These results suggest that plant extracts which contain high ACE inhibitory activities may be useful as anti-hypertension agents and to the treatment of hypertension,
