  • The effects of total ginseng saponin. extracts of Panax ginseng C.A. Meyer, on the differentiation of F9 teratocarcinoma stem cells were studied. F9 stem cells cultured in the presence of ginseng saponin together with dibutyric cAMP became parietal endoderm - like cells. Moreover, the expressions of differentiation marker genes. laminin. type IV collagen. and retinoic acid $receptor-{\beta}(RAR{\beta})$ were increased after treatment of ginseng saponin. Among various ginsenosides purified from crude ginseng saponin, $Rh_1\;and\;Rh_2$ caused the differentiation of F9 cells most effectively. Since ginsenosides and steroid hormone show resemblance in chemical structure. we studied the possibility of the involvement of a steroid receptor in the differentiation process induced by ginsenosides. According to Southwestern blot analysis, a 94 kDa protein regarding as a steroid receptor was detected in F9 cells cultured in the medium containing ginseng saponin. Based on these data, we suggest that ginseng saponin, especially ginsenosides $Rh_1\;and\;Rh_2$ cause the differentiation of F9 cells and the effects of ginsenosides might be exerted via binding with a steroid receptor or its analogous nuclear receptor.

  • Alternative or complementary medicine plays an important role in health care system. Ginseng, being one of the most popular oriental herbs, is believed to contain various steroid hormone activity. Ginseng has been demonstrated pharmacological effect in the cardiovascular, endocrine, central nervous, and immune system. Our objective was to study that total saponin might mediate some of their actions by binding to the steroid hormone receptor, as they share many of the actions of steroid hormone in various physiological system. Using total saponin from Panax Ginseng, we have studied the possibility of total saponin being a potential estrogen receptor, androgen receptor, and retinoic acid receptor ligand. Total saponin activated the transcription of both the estrogen and androgen responsive luciferase reporter plasmids at a concentration of 100$\mu\textrm{g}$/ml in COS cells transiently transfected with the corresponding receptor and hormone responsive receptor plasmids. And total saponin caused a concentration-dependent stimulation of estrogen receptor. Total saponin increased the expression of estrogen responsive c-fos proto-oncogene at the protein level in MCF7 cells at 24 h treatment as examined by Western analysis. The c-fos induction was used as a specific marker of estrogen responsiveness. This activation was inhibited by the specific estrogen receptor antagonist, ICI 182,780. However, total saponin failed to activate the retinoic acid receptor in COS cells transiently transfected with the corresponding receptor and retinoic acid responsive reporter plasmids. These results show that total saponin is capable of activating estrogen and androgen receptors.

  • The presence of saponin, terpenoid, steroid, anthraquinone and flavonoid were screened with the usual test methods in forty five(sixty four parts) Korean plants belonging to Urticaceae, Celastraceae, Rhamnaceae, Sterculiceae and Rubiaceae. Plants were extracted with methanol and fractionated with hexane, chloroform, ethyl acetate and butanol. Each fraction was tested for the components. The result showed that in saponin test, 21 plants were positive and 11 plants were weak positive; in terpenoid and steroid test, 26 plants were strong positive; in anthraquinone test, 20 plants strong positive; in flavonoid test, 31 plants were positive and 9 plants were weak positive.

  • Optimal conditions for hot water extraction of Liriope spicata tuber were investigated with changes in solvent ratio(2∼6 fold) and heating time(1∼5 hr) by response surface methodology. The content of extractable solids increased with an increased in solvent ratio, and the highest content showed at heating time of 3 hr. The content of total steroid saponin increased with a decrease in solvent ratio, and increased with an increase in heating time at increasing the solvent ratio. The content of non-reducing sugar containing oligosaccharides at a lower solvent ratio didn’t show changes depending on heating time, while that at a higher ration decreased with an increase in heating time. Optimal extraction conditions using hot water as the limited conditions of 15∼18% extractable solids, 1.5∼2.0% total steroid saponin, 6∼8% reducing sugar, 6∼7% non-reducing sugar and 13∼15 brix were 3 hrs of heating time and 4 fold of solvent ratio.

  • Pontential mutagenic and antimutagenic activities of four steroidal saponins from Smilax china rhizomes were investigated. These saponins did not revealed mutagneicity in the Ames and SOS umu test. For antimutagenic activity by SOS umu test, two spirostanol glycosides, dioscin and gracillin, inhibited the activity of ${\beta}-galactosidase$ induced by AF-2, but their proto-type furostanol glycosides did not show this activity.

  • Four steroids have been isolated from the subterranean parts of Smilax nipponica Miquel (Liliaceae). The structures of these compounds were characterized on the basis of chemical and speectral data. They were $\beta$-sitosterol, $\beta$-sitosterol-3-O-$\beta$-D-glucopyranoside, neotigogenin-3-O-$\beta$-D-glucopyranoside and a new steroidal saponin designated as smilanippin A which was elucidated as neotigogenin-3-O-$\beta$-D-fucopyranosyl(1$\rightarrow$6)-$\beta$-D-glucopyranos ide.

  • A new norditerpenoid and a known alkaloid were isolated from the alkaloidal fraction of the processed tubers of Aconitum carmichaeli. The structure of the new norditerpenoid alkaloid was elucidated as lipoforesaconitine (1) on the basis of spectroscopic analysis. The known norditerpenoid alkaloid was characterized as lipoyunanaconitine (2). In addition, a new flavonoid, 6'-O-acetylliquiritin (7), along with a known ceramide, (2S,3S,4R,8E)-2-[(2'R)-2'­hydroxylignoceroylamino]-8(E)-octadecene-1,3,4-triol (3), as well as a known steroid saponin, gracillin (8), and three known flavonoids, Iiquiritigenin (4), isoliquiritigenin (5), and liquiritin (6), were also isolated and characterized. All known compounds were isolated from this plant for the first time. The structures of the isolates were established by spectroscopic and chemical methods.

  • 방울비짜루의 MeOH 추출물 및 수포화 BuOH추출물로부터 항균활성을 확인하고 그 원인물질을 구명하던 중 두 종의 steroid saponin을 분리하였다. 이들의 구조확인을 위해 $^1H,\;^{13}C$ NMR 및 2D NMR 등 분광학적 방법을 사용하였으며 최종 이들의 구조가 25S-spirostane계의 steroid saponin인$3-O-[{\beta}-D-glucopyranosyl-(1{\rightarrow}2)-{\beta}-D-glucopyranosyl]-(25S)-spirostan-3{\beta}-ol$$3-O-{{\beta}-D-glucopyranosyl-(1{\rightarrow}2)-[{\beta}-D-xylopyranosyl-(1{\rightarrow}4)]-{\beta}-D-glucopyranosyl}-(25S)-spirostan-3{\beta}-ol$인 것으로 동정되었다. 이 두 화합물은 방울비짜루로부터는 처음으로 분리되었다. 이들 saponin의 항균활성 및 항균 스펙트럼을 검사하기 위하여 20개 균주에 대한 MIC를 실시하였다. 이들은 그중 10개 균주에 대해 $100\;{\mu}g/ml$의 농도에서 세균의 성장을 저지하는 항균력이 있었으며 광범위한 항균 스펙트럼을 나타내었다.

  • Diosgenin(25(R)-spirost-5-en-3${\beta}$-ol) is the steroid saponin, was isolated from Mexican yam(Oioscorea). Estrogenic, progesterogenic and anti-inflammatory effects of diosgenin has been hypothesized due to its structural similarity to estrogen, progesterone precursors. And diosgenin had been reported to lower serum cholesterol in chicken and rabbits fed cholesterol and to decrease liver cholesterol in cholesterol-fed rats. (omitted)
