Ginsenoside Rh4
1.[Chemical constituents of Chinese red ginseng].
Liu D1, Pu S, Qian S, Zhang J. Zhongguo Zhong Yao Za Zhi. 2011 Feb;36(4):462-4.
The chemical constituents of Chinese red ginseng (Panax ginseng) were investigated. The chemical constituents were isolated and purified by silca gel, ODS, and Sephedex LH-20, column chromatography, and preparative HPLC. Their chemical structures were elucidated on the basis of physicochemical properties and spectra data. Fourteen compounds were isolated and identified as: notoginsenoside R2 (1), 20(S) -ginsenoside Rg3 (2), 20(R) -ginsenoside Rg3 (3), 20 (S)-ginsenoside Rg2 (4), 20(R) -ginsenosideRg2 (5), 20 (S)-ginsenoside Rh1 (6), 20(R) -ginsenoside Rh1 (7), ginsenoside Rh4 (8), -Ro (9), -Rb1 (10), -Rg1 (11), Re-(12), Rf (13), maltol (14). Compounds 1, 4, 6, were obtained from red ginseng for the first time. Compounds 2 and 3, 4 and 5-7 were enantiomers respectively, enantiomers 6 and 7 were isolated as monomer for the first time.
2.Immunological adjuvant effect of ginsenoside Rh4 from the roots of Panax notoginseng on specific antibody and cellular response to ovalbumin in mice.
Yang ZG1, Ye YP, Sun HX. Chem Biodivers. 2007 Feb;4(2):232-40.
Ginsenoside Rh(4) (1), a saponin isolated from the roots of Panax notoginseng (Burk.) F. H. Chen, was evaluated for its haemolytic activity and adjuvant potential on specific antibody and cellular response to ovalbumin (OVA) in mice. Compound 1 showed a slight haemolytic effect, its concentration inducing 50% of the maximum haemolysis (HD(50) value) being 407+/-12 microg/ml using a 0.5% suspension of red blood cells. Compound 1 significantly increased the concanavalin A (Con A)-, lipopolysaccharide (LPS)-, and OVA-induced splenocyte proliferation in OVA-immunized mice especially at a dose of 25 microg (P<0.05, P<0.01, or P<0.001). The OVA-specific serum IgG, IgG1, and IgG2b antibody levels were also significantly enhanced by 1 at a dose of 25 microg compared to the OVA control group (P<0.05 or P<0.01). Moreover, the enhancing effect of 1 on the OVA-specific IgG2b antibody responses to OVA in mice was more significant than that of Alum (Al(OH)(3) gel; P<0.
3.Immunological-adjuvant saponins from the roots of Panax notoginseng.
Sun H1, Ye Y, Pan Y. Chem Biodivers. 2005 Apr;2(4):510-5.
The total saponin extract from the dried roots of Panax notoginseng (Burk.) F. H. Chen possesses immunological-adjuvant activities. Guided by in vivo immunological tests, further study on this fraction afforded three active dammarane-type saponins. Their structures were determined on the basis of chemical evidence and extensive spectroscopic methods, including 1D- and 2D-NMR. The novel compound (20S)-protopanaxatriol 20-O-beta-D-glucopyranosyl-(1-->6)-beta-D-glucopyranoside (1), and the two known compounds ginsenoside Rh4 (2) and notoginsenoside K (3) exhibited immunological-adjuvant activities on the humoral immune responses of ICR mice against ovalbumin (OVA).
