OBJECTIVE To explore the liver-toxic fraction in Rhigoma of Dioscorea bulbifera. METHOD The rats were randomized into four groups: control group (20% PVP-water), T001(10% total methanol extraction), F002(5% chloroform fraction) and F003(5% methanol fraction). Direct bilirubin (DBil) and Glutamic-pyruvic transaminase (GPT) were examined, and liver index(More)
Seven lignans having a diarylhydroxybutyrolactone skeleton were isolated from the leaves and stems of Trachelospermum jasminoides (Lindl.) Lem. Their structures were elucidated to be nortrachelogenin 8' -O-beta-D-glucopyranoside (1), nortrachelogenin 5'- C- beta-D-glucopyranoside (2), trachelogenin amide (3), nortracheloside, trachelogenin, tracheloside,(More)
OBJECTIVE To study the flavonoids constituents of Trachelospemum jasminoides. METHODS The compounds were separated and purified by column chromatography with silica gel, and identified by IR, MS, NMR and 2D-NMR. RESULTS Six flavonoids were identified as apigenin (I), apigenin 7-O-beta-glucoside (II), apigenin 7-O-beta-neospheroside (III), luteoloside(More)
Ten compounds, comprising a new C(8) normonoterpenoid glycoside, trachelinoside (1), structurally as 4-(2-O-beta-D-glucopyranosyl)-hydroxyethyl-5,5-dimethyldihydrofuran-2(3H)-one, together with nine known compounds, were isolated from the 85% ethanol extract of the vines and leaves of Trachelospermum jasminoides (Lindl.) Lem.
OBJECTIVE To study the chemical constituents of Ervatamia hainanensis. METHOD The compounds were separated and purified by column chromatography with silica gel, and identified by IR, MS, NMR and 2D-NMR. RESULT Five compounds were identified as I (isolariciresinol 9-O-beta-D-glucopyranoside), II (cycloartenol), III (beta-amyrin acetate), IV(More)
