  • The seasonal variations of the major six flavonol glycosides(kaempferol 2,6-dirhamnosyl glucoside, quercetin 3-O-rutinoside, kaempferol 3-O-rutinoside, isorhamnetin 3-O-rutinoside, quercetin 3-O-coumaroyl glucorhamnoside and kaempferol 3-O-coumaroyl glucorhamnoside) in Ginkgo biloba leaves were investigated. The contents were determined by HPLC on reversed phase $C_{18}$ column. This result showed that the percentage of six flavonol glycosides decreased during the season from 1.57% in May to 0.39% in November. The content of each flavonol glycoside indicated a similar tendency to decrease. However, the contents of rutinosides of kaempferol, quercetin and isorhamnetin fluctuated markedly than those of coumaroyl glucorhamnosides of kaempferol and quercetin and kaempferol 2,6-dirhamnosyl glucoside.

  • Spinoside, new coumaroyl flavone glycoside was isolated from the n-butanol fraction of the mathanolic extract of the whole plant of Amaranthus spinosus and assigned the structure 7-pcoumaroyl apigenin 4-O-${\beta}$ -D-glucopyranoside (1) on the basis of spectroscopic techniques including 1D and 2D NMR spectroscopy. In addition ${\alpha}$ - xylofuranosyl uracil (2), ${\beta}$ -D-ribofuranosyl adenine (3) and ${\beta}$ -sitosterol glucoside (4) have also been isolated for the first time from this species.

  • A new phenolic glycoside, ophiopojaponin D (1), together with two known compounds, was isolated from the tubers of a famous traditional Chinese herb-Ophiopogon japonicus Ker-Gawl. The spectroscopic and chemical data revealed their structures to be 3-tetradecyloxy-4­hydroxy-allylbenzene-4-O-$\alpha$-L-rhamnopyranosyl (1$\rightarrow$6)-$\beta$-D-glucopyranoside (1), 3, 4-dihy-droxy-allylbenzene-4-O-$\alpha$-L-rhamnopyranosyl (1$\rightarrow$6)-$\beta$-D-glucopyranoside (2) and L-pyro­glutamic acid (3).

  • Ginkgo biloba의 세포배양을 통하여 세포성장과 flavonol glycosides의 생성에 영향을 미치는 여러 조건들을 연구하였다. 다양한 지역으로부터 유도된 세포주들의 세포성장과 flavonol glycosides의 생합성 능력은 서로 차이가 있었다. 이들의 캘러스 및 현탁 세포는 배지조건과 배양조건에 따라 성장 및 f1avonol glycosides 생합성에 많은 영향을 받았었다. 특히 배양조건 중 빛의 영향은 현저하여 명조건에서의 f1avonol glycosides의 생성은 암조건보다 10배 이상 증가함을 알 수 있었다.

  • A new stereoisomeric monoterpene glycoside and five already-known compounds were isolated from the n-BuOH soluble fraction of Clematis heracleifolia leaves. On the basis of spectral data, the structures of the isolated compounds were identified as protocatechuic acid (1), ferulic acid (2), caffeic acid (3), aesculin (4), (6Z)-9-hydroxylinaloyl glucoside (5), and 9-hydroxylinaloyl glucoside (6) and these were isolated for the first time from this plant. Among these compounds, (6Z)-9-hydroxylinaloyl glucoside (5) is a newly isolated from plant source.

  • A new cycloartane glycoside was isolated from the dried whole herbs of Camptosorus sibiricus Rupr By means of chemical (hydrolysis) and spectroscopic methods (IR, 1D, and 2D NMR, ESI-MS), the structure was established as $3{\beta}$, $7{\beta}$, $24{\beta}$, 25, 30-pentahydroxycycloartane-3-O-${\beta}$-D-glucopyranoside-24-O-${\beta}$-D-glucopyranoside (1).

  • We analyzed and compared profiles of flavonols extracted from leaves and exocarps of the grape Kyoho by TLC, HPLC and UV spectrophotometry. In the exocarps, quercetin 3-O-glucoside was the main compound while isorhamnetin 3-O-glycoside (I) was present in minor amounts. In leaves, on the other hand, quercetin 3-O-glucoside and quercetin 3-O-glucoside-7-O-glucronide were the major compounds while isorhamnetin 3-O-glycoside (II) and kaempferol 3, 7-O-diglycoside were present in minor amounts.
