The evaluation of ginseng and its congeners by droplet counter-current chromatography (DCC). Otsuka, Hideaki; Morita, Yukio; Ogihara, Yukio; Shibata, Shoji (Fac. Pharm. Sci., Univ. Tokyo, Tokyo, Japan). Planta Med., 32(1), 9-17 (English) 1977. CODEN: PLMEAA. DOCUMENT TYPE: Journal CA Section: 63 (Pharmaceuticals) Saponin exts. from Korean ginseng (Panax ginseng), American ginseng (P. quinquefolium), San-Chi ginseng (P. pseudoginseng notoginseng), and Japanese Chikusetsu ginseng (P. pseudoginseng japonicus) were subjected to droplet counter-current chromatog. using :6:40 CHCl3-MeOH-PrOH-H2O as the solvent system with the fractions detd. colorimetrically. The Korean ginseng contained ginsenoside Rb1 [41753-43-9], ginsenoside Rb2 [11021-13-9], ginsenoside Rc [11021-14-0], ginsenoside Re [52286-59-6], and ginsenoside Rg1 [22427-39-0] as major components and ginsenoside Rd [52705-93-8] and ginsenoside Rf [52286-58-5] as minor components. The American and San-Chi samples differed slightly; e.g. American ginsenoside lacked ginsenoside Rg1 and had another unknown component whereas the Japanese Chikusetsu samples were very different.

Age and seasonal dynamics of panaxosides contents in leaves of cultivated Panax ginseng C

Age and seasonal dynamics of panaxosides contents in leaves of cultivated Panax ginseng C. A. Mey. Legosteva, A. B.; Grushvitskii, I. V.; Minina, S. A. (Leningr. Khim.-Farm. Inst., Leningrad, USSR). Rastit. Resur., 22(4), 523-6 (Russian) 1986. CODEN: RRESA8. ISSN: 0033-9946. DOCUMENT TYPE: Journal CA Section: 63 (Pharmaceuticals) Section cross-reference(s): 11 Possibility of manufg. panaxosides from leaves harvested in autumn from P. ginseng grown for roots was explored. The yield of triterpenoid glycosides from 3-, 4-, 5-, and 6-yr-old plants was 0.4, 1.In this article, certain chemicals are used. Some of their cas registry numbers are 22427-39-0 and 41753-43-9 0, 1.1, and 1.4 g/m2, resp. The panaxoside wt. of air-dried aerial part was 4.0, 10.5, 12.0, and 17.0 g/m2, resp. This increase offset the decreasing content of total panaxosides which was 10.0, 9.5, 8.7, and 8.3 air-dried-wt.%, resp. Leaves of 4-yr-old plants harvested during flowering (June), fruit-ripening (Aug.), and the beginning of withering (Sept.) contained 10.8, 10.1, and 10.1 dry-wt.% panaxosides, resp. The compn. of panaxosides did not depend on age or season. The total glycosidic fraction contained 310 panaxosides of which Rb1 [41753-43-9], Rc [11021-14-0], Re [52286-59-6], Rf [52286-58-5], Rg1 [22427-39-0], and Rg2 [52286-74-5] were identified. .
