  • Cell lines of Ginkgo biloba were derived from different plant parts and from ten varieties spanning various geographic locations. They had various properties of growth and product formation. More than three flavonol glycosides were present in low concentration in callus and suspension cultures. Cell growth and biosynthesis of flavonol glycosides were found to be affected by medium composition. Culture conditions which influenced cell growth and product formation were also examined. Light stimulated the flavonol glycosides biosynthesis and ten times higher flavonol glycosides content was obtained as compared with the result without light.

  • The herbs of Orostachys japonicus (Crassulaceae) have been used to treat gastric cancer, gastric ulcer or hemorrhage. Flavonoid glycosides, mainly kaempferol (Kp)- and quercetin (Qc) glycosides, have been isolated from O. japonicus; however, no quantitative information on those flavonol glycosides and no peroxynitritescavenging activity of the Orostachys extracts have been reported. In this study, Kp- and Qc glycosides were qualitatively and quantitatively analyzed by high-performance liquid chromatography (HPLC) in eight Orostachys and a Meterostachys species including O. japonicas, O. margaritifolius, O. chongsunensis, O. minuta, O. ramosus, O. malacophylla, O. latiellipticus, O. iwarenge, O. iwarenge for. magnus, and Meterostachys sikokiana distributed or cultivated in Korea. Distinctively, O. margaritifolius contained two flavonol 3,7-di-O-glycosides of Kp 3,7-di-O-glucoside and Kp 3-rhamnosyl-7-glucoside, but O. japonicus had two flavonol 3-O-rutinosides, Kp 3-rutinoside and Qc 3-rutinoside. The three species of O. margaritifolius (24.36 mg/g MeOH extract), O. japonicus (21.28 mg/g), and O. minuta (19.50 mg/g) showed relatively higher flavonoid contents. The flavonol glycosides were analyzed using eight standard compounds (Kp, Qc, Qc 3-O-rhamnoside, Qc 3-O-glucoside, Kp 3- O-rutinoside, Qc 3-O-rutinoside, Kp 3-O-rhamnosyl-7-O-glucoside, Kp 3,7-di-O-glucoside). The present HPLC method was validated to verify the linearity, precision, and accuracy. In addition, the peroxynitrite-scavenging activity was also discussed.

  • A study was carried out to evaluate flavonol glycosides in leaves of Symplocarpus renifolius (Araceae). From the water fraction of the MeOH extract, three new flavonol glycosides were isolated along with three known compounds, Kaempferol-3-O-$\beta$-glucopyranosyl-($1{\rightarrow}2$)-$\beta$-D-glucopyranosyl-7-O-$\beta$-D-glucopyranoside, quercetin-3-O-$\beta$-D-glucopyranosy-1-($1{\rightarrow}2$)-$\beta$-D-glucopyranoside, and caffeic acid. The structures of the new flavonol glycosides were elucidated by chemical and spectral analyses a quercetin-3-O-$\beta$-D-glucopyranosyl-($1{\rightarrow}2$)-$\beta$-D-glucopyranosyl-7-O-$\beta$-D-glucopyranoside, isorhamnetin-3-O-$\beta$-D-glucopyranosyl-(1 2)-$\beta$-D-glucopyranosyl-7-O-$\beta$-D-glucopyranosdie, and quercetin-3-O$\beta$-D-glucopyranosyl-($1{\rightarrow}2$)-$\beta$-D-glycopyranosyl-7-O-($6^{IIII}$-trans-caffeoyl)-$\beta$-D-glucopyranoside.

  • Our previous report demonstrated that certain flavonoid aglycones such as apigenin (flavone), quercetin, morin (flavonols), and biochanin A (isoflavone) showed in vivo antiinflammatory activity via topical and oral routes of adminstation. As a continual study, the various flavonoid glycosides have been evaluated in mouse ear edema assay using archidonic acid or croton-oil as a inflammagen. Flavonoids were orally administered (2 mg/mouse) and ear edema inhibition was measured. Significant antiinflammatory activities were found esepcially in flavone and flavonol glycosides (15-29% inhibition) although the flavonoid derivatives tested showed less antiinflammatory activity than hydrocortisone or indomethacin. Chalcone and flavanone derivatives were not significantly active. And in general, flavonol glycosides of kaempferol-type were found to have a higher oral antiinflammatory activity than that of flavonol glycosides of quercetin-type in mice.

  • 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.

  • Ten flavonol glycosides were isolated from the EtOAc fraction of the MeOH extract of Metaplexis japonica Makino. Structures of the flavonoids were elucidated on the basis of spectroscopic data and comparison with literature values. The flavonoids were found to be mostly common flavonol 3-glycosides. It is of interest that the sacchaide parts of the isolates were pairs of arabinosides, glucosides, galactosides, rutinosides and robinobiosides of kaempferol and quercetin. All of these compounds were isolated for the first time from this plant.

  • The seasonal variation of two flavonol glycosides, icariin and epimedoside A, in the aerial parts and underground parts of Epimedium koreanum from June through September was investigated. The icariin concentration was decreased with time in both parts. Epimedoside A concentration was fluctuated, being highest in June and lowest in July in the underground parts. In the aerial parts, however, it was almost same in concentration. Determinations were made of the occurrence of two new flavonol glycosides, 2‘-O-rbamnosyl ikarisoside A and 2’-O-rhamnosyl icarisid II in the aerial parts and their changes in concentration were similar to those in the underground parts, being highest in July in both parts.

  • The contents of flavonol glycosides, $kaempferol-3-O-{\beta}-D-glucoside$(1), $kaempferol-3-O-{\beta}-D-glactoside$ (2), $kaempferol-3-O-{\beta}-D-rhamnoside$ (3), $quercetin-3-O-{\beta}-D-glucoside$ (4) and $quercetin-3-O-{\alpha}-D-rhamnoside$ (5) in the houseleeks controlled by night-break, day-length control, and temperature during overwintering were determined to be compared with those in wild one. The contents of the flavonol glycosides 1-5 in the houseleeks were decreased roughly with warming during overwintering, and increased with longer light duration under the day-length control experiments. While warming functioned negatively on the production of the flavonol glycosides in the houseleek, longer light irradiation did positively during overwintering.
