We determined the structure of main saponin which extracted from the shoot of Aralia Elata. The results were as follows. 1. The main aglycons and suger of the total saponins of Nr2 sample were identified as oleanolic acid and hederagenin, and glucose, arabinose and rhamnose. A probable new aglycon was isolated and inferred as 1, 3-methylenedioxy-3-dehydroxyoleanolic acid. 2. One compound of Fh saponin (named as Elatoside $Fh_2$) which was obtained first in this species was elucidated as 3-O-$({\alpha}-L-arabinopyranosyl(1{\rightarrow}2)-{\beta}-D-gluco-pyranosyl)$-28-O-${\beta}-D-glucophyranosyl$ oleanolic acid on the basis of chemical and spectral evidence of IR, $^1H$, $^{13}C-NMR$ and MS.

The objective of this study was to investigate the effect of crude ginseng total saponins (CGS) against airway inflammation (AI) and airway hyperresponsiveness (AH) induced by diesel exhaust particles (DEP) in mice. AI and AH were induced by the intratracheal instillation with 0.1 $mg/m{\ell}$ of DEP suspension once a week for 10 weeks combined with ovalbumin (OVA) sensitization. Mice were also treated orally with 75 $mg/m{\ell}$ of CGS, 5 days a week for 10 weeks. Oral CGS treatment decreased in the level of serum immunoglobulin (IgE) and histamine increased by DEP and OVA, and declined respiratory resistance. It also dropped an enhanced infiltration of eosinophils in the bronchoalveolar lavage fluid (BALF) of mice, and an increased T helper type 2 cell derived cytokine levels such as of interleukin (IL)-4, IL-13 and IL-5 in the BALF. However, it did not influence T helper type 1 cytokine such as interferon-gamma in the BALF. These results indicate that CGS may alleviate allergen-related AI and AH in mice and may play an important role in the modulation of asthmatic inflammation.

The ginseng plant (Panax ginseng Meyer) has a large number of active ingredients including steroidal saponins with a dammarane skeleton as well as protopanaxadiol and protopanaxatriol, commonly known as ginsenosides, which have antioxidant, anticancer, antidiabetic, anti-adipocyte, and sexual enhancing effects. Though several discoveries have demonstrated that ginseng saponins (ginsenosides) as the most important therapeutic agent for the treatment of osteoporosis, yet the molecular mechanism of its active metabolites is unknown. In this review, we summarize the evidence supporting the therapeutic properties of ginsenosides both in vivo and in vitro, with an emphasis on the different molecular agents comprising receptor activator of nuclear factor kappa-B ligand, receptor activator of nuclear factor kappa-B, and matrix metallopeptidase-9, as well as the bone morphogenetic protein-2 and Smad signaling pathways.

Platycodon grandiflorum root (Platycodi radix) saponins, platycosides, have been used as health supplements and food items for the treatment of respiratory disorders and pulmonary diseases. Deglycosylated saponins have been known to exert stronger biological effects than their glycosylated forms. In the present study, glycosylated platycosides in Platycodi radix extract were biotransformed into deglycosylated 3-O-β-ᴅ-glucopyranosyl platycosides, including 3-O-β-ᴅ-glucopyranosyl platycodigenin, 3-O-β-ᴅ-glucopyranosyl polygalacic acid, and 3-O-β-ᴅ-glucopyranosyl platyconic acid, by pectinase from Aspergillus aculeatus. This is the first report on the quantitative enzymatic production of 3-O-β-ᴅ-glucopyranosyl platycosides. The chemical structures of 3-O-β-ᴅ-glucopyranosyl platycosides were identified with LC/MS. Moreover, the biotransformation pathways of the three types of platycosides in Platycodi radix into 3-O-β-ᴅ-glucopyranosyl platycosides were established.

The effects of ginseng total saponins (GTS) on the action of U-50,488H, a $textsc{k}$-opioid receptor agonist, on the electrically induced twitch responses of mouse vats deferens were studied. U-50,488H ($10^9$~$10^{-5}$M) inhibited the twitch contractions in a dose-dependent manner, which were caused by adenosine 5'-triphosphate (ATP) released from the stimulated sympathetic nerve, and this effect was antagonized by naloxone ($10^6$ M). GTS, which itself induced the inhibition of the twitch contractions, acted additively to U-50,488H, GTS and U-50,488H had no effect on the tension of the unstimulated organs. The contractions elicited by ATP were not affected by U-50,488H, but inhibited by GTS. These results suggest that U-50,488H suppressed the twitch contractions by the inhibition of neurotransmitter release from presynaptic nerve terminals via action on opioid receptor, but G75, by inhibiting the action of the neurotransmitter on the smooth muscle.

Cytotoxic activitiy of seven hederagenin saponins isolated from the root of Dipsacus asper were investigated in vitro against L1210, HL-60 and SK-OV-3 tumor cell lines by the MTT method. $3-O-\alpha-L-rhamnopyranosyl-(1{\rightarrow}2)-\alpha-L -arabinopyranosyl$ hederagenin (2),\;$3-O-\beta-D­xylopyranosyl-( 1{\rightarrow}3)-\alpha-L-Rhamnopyranosyl-(1{\rightarrow}2)-\alpha-L -arabinopyranosyl$ hederagenin (6) and $3-O-\beta-D-glucopyranosyl-(1{\rightarrow}3)-\alpha-L-rhamnopyranosyl-( 1{\rightarrow}2)-\alpha-L-arabinopyranosyl$ hederagenin (7) exhibited the potent cytotoxicity against the three tumor cell lines with $IC_{50}$ values ranging from 4.7 to 8.7 ${\mu}g/mL$, with the exception of compound 7, which exhibited weak cytotoxic activity against SK-OV-3 $(IC_{50}\;22.5\;{\mu}g/mL)$. Other compounds did not exhibit any cytotoxic activity $(IC_{50}>30{\mu}g/mL)$.

Psychotropic actions of crude ginseng saponins(CGS), pure ginsenoslue Rbl(GS-bl) and gin- senoside Rgl(GS-gl) isolated from the root of Panax ginseng, were evaluated by determining their effects on agonistic behavior in male(Experiment 1) and female(Experiment 2) mice, using a biologically relevant method. The results of experiment 1 demonstrated that CGS and GS-bl significantly suppressed aggressive episodes (offensive sideways posture and attack bite) in a dose-dependent manner when the resident was drugged, whereas G5-gl was ineffective. However, when the intruder was treated with one of three ginseng saponins, agonistic behavior between resident and intruder males was not altered. In experiment 2, acute administration of CGS and G5-bl significantly suppressed maternal aggression, whereas GS-gl was ineffective. As compared with the vehicle-treated group, chronic treatment with CGS and GS-bl significantly suppressed maternal aggression, while GS-gl showed a tendency to increase the frequency of attack bite by females. These findings clearly indicate that the root of Panax ginseng contains psychoactive ingredient, which can suppress both intermale and maternal aggression in mice. We suggest that the present results have important implications for the clinical usefulness of ginseng saponins in psychiatric medicine.

The quality inspection was made on commercial Korean ginseng extract (Company A, B, C, D, E, F, G and H), particularly on samples available in Seoul market area. The results were as follews: 1) Among the ginseng extract products out of eight different manufactures, the moisture content of D company's product showed 46.5%, and other companys' met with the moisture standard for ginseng extracts. And protein, fat, ash, fiber and total sugar were about $9.87{\sim}21.07%,\;0.46{\sim}1.62%,\;6.55{\sim}7.88%,\;0{\sim}0.15%\;and\;58.58{\sim}76.74%$, respectively. And residue of D and F company products showed 3.25% and 3.61% which exceed the standard, and other company products met with residue test specifications. 2) The contents of ginseng saponins were 16.16% and 13.12%, respectively, for the C and H company products. However, other company's showed below 9%. By fractional distribution of ginseng saponins, it is supposed to be white ginseng and lateral ginseng that were mostly used as raw materials for ginseng extract manufacturing.

This study was carried out to investigate the protective effect of Red Ginseng Saponins on 2,3,7,8-Tetrachlorodibenzo-p-dioxin (TCDD) induced toxicities in guinea pigs ($200{\pm}10$ g). Normal control (NC) group guinea pigs ($200{\pm}10$ g) received vehicle and saline, while the TCDD-treated (TT) group was given water-extract (WE), saponin fraction (SF) and non-saponin fraction (NSF). Korean red ginseng fractions were administered from 1 week before TCDD-exposure for 4 weeks. Body weight loss and deteriorated clinical parameters related to sugar metabolism and liver function such as lipase and AST, respectively, these were significantly reduced by both saponin and non-saponin fractions. However, increase of lipase was attenuated by the saponin fraction in a dose-dependent manner. Only AST was affected by the saponin fraction. The results suggest that saponins are active substances in the Korean red ginseng water extract against TCDD induced toxicities in Guinea pigs.

Background: Paris polyphylla (Chinese name: Chonglou) had been traditionally used for a long time and shown anti-cancer action. Based on the previous study that paris polyphylla steroidal saponins (PPSS) induced cytotoxic effect in human lung cancer A549 cells, this study was designed to further illustrate the mechanisms underlying. Materials and Methods: The mechanisms involved in PPSS-induced A549 cell death were investigated by phase contrast microscopy and fluorescence microscopy, flow cytometry and western blot analysis, respectively. Results: PPSS decreased the proportion of viable A549 cells, and exposure of A549 cells to PPSS led to both apoptosis and autophagy. Apoptosis was due to activations of caspase-8, caspase-3, as well as cleavage of PARP, and autophagy was confirmed by up-regulation of Beclin 1 and the conversion from LC3 I to LC3 II. Conclusions: PPSS was able to induce lung cancer A549 cell apoptosis and autophagy in vitro, the results underlining the possibility that PPSS would be a potential candidate for intervention against lung cancer.
