  • From the roots of Puisatiila koreana, three monodesmosides(pulsatilla saponins A, B and D) and two bisdesmosides(pulsatilla saponins F and H) were isolated. The structure of these saponins have been determined as hederagenin 3-O-${\beta}$-L-rhamnopyranosyl($1{\to}2$)- ${\alpha}$-L-arabinopyranoside(A), hederagenin 3-O-${\beta}$-D-glucopyrano syl($1{\to}4$) - ${\alpha}$-L-arabinopyranoside(B), hederagenin 3-O- ${\alpha}$-L-rhamnopyranosyl ($1{\to}2$)-[${\beta}$-D-glucopyranosyl($1{\to}4$]-${\alpha}$-L-arabinopyranoside(D), 3-O-${\alpha}$-L-rhamnopyranosyl($1{\to}2$)-{${\alpha}$-L-arabinopyranosyl hederagenin 28-O-${\alpha}$-L-rhamnopyrano syl($1{\to}4$)-${\beta}$-D-glucopyrano syl($1{\to}6$)-${\beta}$-D-glucopyranosyI ester (F) and 3-O-${\alpha}$-L-rhamnopyranosyl($1{\to}2$)-[${\beta}$-D-glucopyranosyl($1{\to}4$)]- ${\alpha}$-L-arabinopyranosyl hederagenin 28-O-${\alpha}$-L-lharnnopyranosyl($1{\to}4$)-${\beta}$-D-glucopyranosyl($1{\to}6$)-${\beta}$-D-glucop yranosyl ester(H) on the basis of chemical and spectral studies. Pulsatilla saponin B is the first report of its presence in plants but saponins A, D, F, and H have recently been isolated from the same genus p. cernua.

  • The enantiomers of the bronchodilator terbutaline were separated by reversed-phase high performance liquid chromatograhy after derivatization with 2,3,4,6-tetra-O-acetyl-\beta-D-glucopyranosyl isothiocyanate(GITC) reagent. The derivatization proceeded quantitatively within 1 h at room temperature. The corresponding diastereomeric thiourea derivatives were well resolved on an ODS column with acetonitrile-acetate buffer as a mobile phase. Elution orders of the diastereomers were confirmed by derivatization of R-(-)-terbutaline and S-(+)-terbutaline which were collected by semi-preparative chiral HPLC using Sumichiral OA-4700 column. The native fluorescence of terbutaline was quenched by derivatization with GITC. The detection limit was 25ng when monitored at UV 278 nm.

  • The roots of Dipsacus asper are used in traditional Chinese medicine as an analgesic, enhancement of liver activity, an anti-inflammatory agent and the treatment of fractures. In order to investigate the antioxidative activity, Dipsaci Radix was extracted with MeOH and fractionated with $CHCl_3$, EtOAc, BuOH and water. MeOH ex. and its solvent fractions were determined on the free radical scavenging activity by DPPH method and antioxidative activity on low density lipoprotein oxidation. The EtOAc and BuOH fractions showed antioxidative activities and from their fractions, two compounds were isolated and identified as hederagenin 3-O-${alpha}$-L-arabino pyranoside (compound 1) and O-${\alpha}$-L-arabinopyranosyl hed-eragenin 28-O-${\beta}$-D-glucopyranosyl ($1{\to}6$)-${\beta}$-D-glucopyranosyl ester (compound 2). Saponin glycoside, compound I showed anti-oxidative activity.

  • The compounds, 1-Linoleic-2-olein (1), stigmasterol (2), 1,4-glucopyranosyl-1',4'-glucopyranosyl-1",4"-glucopyranoside (3), 2',3'-diphosphoryl-1'-propanoxy-${\beta}$-D-glucopyranoside (4), 1-Linoleic-3-olein (5), l-(N,N,N-trimethyl ethyl amino phosphoryl)-2,3-dilinolein ion (6) and glyceryl phosphate (7) were isolated and identified from the Mushroom of Pholiota adiposa for the first time by column chromatography, TLC, UV, IR, $^1H$ and $^{13}C$ NMR, EI-MS, and FAB-MS. The compounds 1 and 2 were found to have weak cytotoxicity against P388 murine leukemia cells. However, the compounds 6 and 7 did not show any cytotoxicity.

  • From the methanolic extractive of the fruits of Quercus acutissima $C_{ARRUTHERS}$(Fagaceae) a mixture(QC-A saponin) of two ester glycosides, which were named as dotorioside I(3) and ll(4), was separated by silica gel column chromatography and HPLC. The structures of these two glycosides including their genuine aglycones(1,2) were elucidated as 1: $2{\alpha}$, $3{\beta}$, $19{\alpha}$, 23-tetrahydroxyolean-12-en-28-oic acid, 2: $2{\alpha}$, $3{\beta}$, $19{\alpha}$, 23-tetrahydroxyurs-12-en-28-oci acid, 3: 28-O-${\beta}$-D-glucopyranosyl ester of 1, 4: 28-O-${\beta}$-D-glucopyranosyl ester of 2, respectively, on the basis of chemical and spectral evidence.
