본 연구에서는 밤차로부터 용출한 차액의 단당류, 아미노산 및 카페인을 시판중인 현미녹차와 결명자차의 차액과 비교분석함을써 밤차의 기능성 건강음료로 활용하기 위한 기초자료를 규명하였으며 그 결과는 다음과 같다. 1. 현미녹차의 차액에는glucose와 galactose약 20:1 정도의 비율로 검출되었으며 용출시간이나 용출온도에 따른 당류의 변화는 적다. 2. 밤차의 차액에는 glucose, galactose, mannose등이 약 100:1:10의 비율로 존재하여 용출시간이나 용출온도에 의한 변화는 적다. 특히 mannoxe는 천연에서 유리상태로존재하기 어려운 희귀한 유리당이다. 3. 결명자차 차액에서는 당류를 확인할 수 없을 정도로 낮은 농도를 나타냈으며 결명자차의 amino산 함량은 현미녹착나 밤속껍질차의 아미노산 함량에 의해 1.6~1/7에 지나지 않았다.4. 현미녹차의 차액 중 아미노산은 glutamic acid, aspartic acid, serine, methionine, alanine 등의 순서로 검출되었으며, 용출온도와 용출시간에 비례하여 농도가 증가하였고, 아미노산의 용출은 대부분 첫회에 이루어지고 있다는 것을 알 수 있었다. 5. 밤차의 차액 중에 아미노산은 alanine, asparagine, aspartic acid, proline, valine 등의 순으로 많이 함유되어 있고, alanine, asparagine, proline등은 현미녹차에 비하여 함유량이 많으며 glutamic acid, serine, methionine, glutamine 등은 상대적으로 소량 함유되어 있었다. 용출온도와 용출시간에 비례하여 농도가 증가하는 경향을 나타냈으며 아미노산의 요출은 대부분 첫회에 이루어지고 있다는 것을 알수 있었다. 6. 현미녹차는 카페인을 126~162 mg/L 정도로 다량 함유하고 있으나 밤차나 결명자차는 함유하지 않았다.

Allelopathic inhibition by substance(s) originated from sicklepod(Cassia tora L.) seed on germination of other plant seeds, was confirmed and used to elucidate general mechanism of allelopathy which was occurred widly in natural and/or agricultural ecosystems. The mechanism was deduced from changes in water contents, ${\alpha}$-amylase activities, protease activities, concentrations of abscisic acid and total phenolic compounds during germination of rice and radish seeds treated with water-soluble extracts of sicklepod seeds. The results obtained were summarized as follows. 1. The % germinations of radish, rice, lettuce, barley seeds were decreased by substances originated from crushed sicklepod seeds. 2. By the treatment of water-soluble extracts of sicklepod seeds, the inhibition of germination of radish seeds was occured with the sequential phenomena of increase of protease activity(synthesis), decrease of water content and increase of total phenolic compounds content. 3. In rice, the inhibition of seed germination by the water-slouble extracts of sicklepod seeds was related to increase of abscisic acid concentration and then decrease of ${\alpha}$-amylase activity(synthesis).

This study was conducted to investigated the change of volatile flavor components of Cassia tora seeds during roasting treatments. The flavor components of Cassia tora seeds were analyzed by gas chromatography(GC) and combined gas chromatography-mass spectrometry(GC/MS). Among the flavor compounds collected by simultaneous steam distillation and extraction(SDE) method, 38 components were separated and identified. They consisted of 3 pyrazines, 4 pyrroles or pyridine, 4 alcohols, 11 aldehydes or ketones, 9 furans or phenols and 7 others. The flavor compounds collected from unroasted Cassia tora seeds were 7 components. During roasting process, many other flavor components were formed and increased in their contents. The contents of pyrazines and furans were highest and increased conspicuously, whereas, the contents of aldehydes, ketones, alcohols and pyridines were not increased significantly.

In order to explore the brassinosteroid-active component in Cassia tora, methanol extract of immature seeds was purified by sequences of solvent fractionation, silica gel adsorption chromatography, Sephadex LH-20 chromatography, charcoal adsorption chromatography and Bondesil chromatography. The activity of brassinosteroid was monitored by the rice inclination test and its presence could be confirmed in each purification step. The purified active components were separated by silica gel adsorption chromatography. Brassinosteroid substances in separated active fractions were identified as teasterone, castasterone, brassinolide by TLC and HPLC. Our work is probably the first report of endogenous brassinosteroid in Cassia tora. The content of brassinosteroid in Cassia tora as converted into brassinolide was $3.5{\sim}5.5\;ng/g$ fresh weight. The order of brassinosteroid contents was toward to be teasterone, castasterone, brassinolide.

The effects of roasting temperature and time on the antioxidant activities of Cassia tora L. were investigated. In comparison with raw seeds (7.15 mg TAE/g), roasted seeds contained a significantly higher total polyphenol content (p<0.05). However, seeds roasted at a higher temperature ($250^{\circ}C$) for 10 min showed a significantly lower total polyphenol content (2.30 mg TAE/g; p<0.05). The electron donating abilities of Cassia tora L. seeds increased with an increase in roasting time; further, seeds roasted for 5 min at lower temperatures showed higher electron donating abilities (80.61% at $175^{\circ}C$; 80.75% at $200^{\circ}C$) than did seeds roasted for 5 min at higher temperatures (76.26% at $225^{\circ}C$; 77.35% at $250^{\circ}C$). Seeds roasted at lower temperatures showed adequate L values, regardless of roasting time; by contrast, seeds roasted for 10 min at higher temperatures, showed markedly lower L values. Our results indicate that roasting temperature and time must be controlled to produce high-quality Cassia tora L. products.

The present study was undertaken to evaluate the anti-hyperlipidemic activity of Albizzia julibrissin and Cassia tora L. extract mixtures in high fat diet-induced hyperlipidemic rats. In high-fat diet fed hyperlipidemic rats, oral treatment with Albizzia julibrissin and Cassia tora L. extracts resulted in decreased levels of total serum cholesterol and triglycerides, epididymal fat pad (EFP) weights, and activities of hepatic glucose-6-phosphate dehydrogenase (G6PDH) and malic enzyme, while the levels of feces production and high-density lipoprotein (HDL)-cholesterol were increased, compared with untreated control. Therefore, these results suggest that Albizzia julibrissin and Cassia tora L. extract mixtures can ameliorate hyperlipidemia.
