triterpene glycoside/인삼속

Optimization of multiple reaction monitoring mass spectrometry (MRM-MS) parameters of triterpene glycosides (TGs) using traditional infusion methods remains to be labor-intensive. However, it was found that mild gas phase decompositions of protonated and ammoninted precursors (DPAP) of TGs could

Two new dammarane triterpene glycosides named notoginsenosides Rw 1 (1) and Rw 2 (2) were isolated from the rhizomes of Panax notoginseng, together with 20 known compounds including protopanaxadiol (3), protopanaxatriol (4), ginsenosides Rb1 (5), Rd (6), Re (7), Rg1 (8), Rg2 (9), 20-(S)-Rg3 (10),

A saponin fraction and triterpene glycosides Rb1, Rb2 and Rg1 from Panax ginseng C. A. Meyer (saponins) were shown to inhibit the hyperosmotic hemolysis of erythrocytes. Using scanning electron microscopy and light scattering, saponins were found to restore the shape of the cells by inhibiting their

Three new triterpene glycosides ursan-3β,19α,22β-triol-3-O-β-D-glucopyranosyl (2'→1″)-β-D-glucopyranoside (1), ursan-3α,11β-diol-3-O-α-D-glucopyranosyl-(6'→1″)-α-D-glucopyranosyl-(6″→1‴)-α-D-glucopyranosyl-(6‴→1‴')-α-D-glucopyranoside (2) and

Five new dammarane-type triterpene glycosides, floralquinquenosides A, B, C, D, and E, were isolated from the flower buds of American ginseng, Panax quinquefolium L., together with 18 known dammarane-type triterpene glycosides and 3 flavonoid glycosides. The structures of new floralquinquenosides

Certain ginsenosides, also known as triterpene glycosides, have been recently reported to have a characteristic effect on cultured intestinal and leukemia cell growth. Ginsenoside aglycones 20(S)-protopanaxadiol (PD), 20(S)-protopanaxatriol (PT), and ginsenoside Rh2 have been identified as having a

Further investigation on the saponins of the flower-buds of Panax ginseng C. A. Meyer has resulted in the isolation and structural elucidation of a pair of new 24-epimers of dammarane type saponins named ginsenoside I and II. The structures of the epimers were characterized on the basis of chemical

The influence of dammaran triterpene glycosides (ginsenosides Rb1 and Rg1) from Panax Ginseng C.A. Meyer and their aglycones on the phase transfers of multilayer vesicles of dipalmitoylphosphatidyl choline was studied. Ginsenosides Rb1 and Rg1 and aglycone 20(S) protopanaxatriol insignificantly

Ginsenoside Re is a triol type triterpene glycoside and is abundantly present in ginseng berry. In the present study, we verified that ginsenoside Re can be transformed into less-polar ginsenosides, namely, Rg2, Rg6, and F4, by heat-processing. The products of heat-processed ginsenoside Re inhibited

A majority of potential radioprotective synthetic compounds have demonstrated limited clinical application owing to their inherent toxicity, and thus, the seeking of naturally occurring herbal products, such as ginseng, for their radioprotective capability has become an attractive alternative. In
