A novel triterpenoid saponin, pseudo-ginsenoside-RI3, isolated from the rhizomes of Panax pseudo-ginseng subsp. himalaicus var. angustifolius has been characterized as 3-O-beta-D-glucopyranosyl(1----2)-beta-D-glucuronopyranosyl (1----6)-beta-D-glucopyranosyl
From rhizomes and roots of Panax vietnamensis Ha et Grushv., Araliaceae, commonly known as Vietnamese Ginseng, two new acetylate saponins named vina-ginsenoside-R1 (13) and vina-ginsenoside-R2 (15) were isolated. On the basis of chemical and spectral data, 13 was formulated as monoacetyl
A new dammarane-type triterpenoid saponin, chikusetsusaponin VII (1), and nineteen known triterpenoid saponins, ginsenoside Rb1 (2), ginsenoside Rb3 (3), ginsenoside Rc (4), ginsenoside Rd (5), ginsenoside Re (6), ginsenoside Rg1 (7), ginsenoside Rg2 (8), ginsenoside Rh1 (9), notoginsenoside R1
Panax pseudo-ginseng subsp. pseudo-ginseng has a carrot like root with a small rhizome. It was shown that the saponin composition of roots and rhizomes of this subspecies collected in Tibet and China was extremely poor. From the roots and rhizomes collected in Central Nepal, (specimen-PNct), only a
A comparative study on the triterpene saponins of 47 samples of Ginseng drugs derived from 12 Panax taxa was conducted using a reverse-phase high-performance liquid chromatography (HPLC)method. Eleven ginsenosides, which represent 4 types of typical sapogenins, were chosen as standards for
