Carbon-13 chemical shifts of isoprenoid-β-D-glucopyranosides and -β-D-mannopyranosides. Stereochemical influences of aglycone alcohols
Antiyeast steroidal saponins from Yucca schidigera (Mohave yucca), a new anti-food-deteriorating agent.
A saponin fraction from the stems of Yucca schidigera exhibited potent growth-inhibitory activities against certain food-deteriorating yeasts, film-formingYeasts, and dermatophytic yeasts and fungi, and the relationship between the antiyeast activities and the structures of these saponins is described.
Studies on Balanites aegyptiaca fruits, an antidiabetic Egyptian folk medicine.
An aqueous extract of mesocarps of the fruits of Balanites aegyptiaca exhibited a prominent antidiabetic activity by oral administration in streptozotocin induced diabetic mice, and two new steroidal saponins were isolated.
13C nmr study of α- and β-anomeric pairs of d-mannopyranosides and l-rhamnopyranosides
Degradation of ginseng saponins under mild acidic conditions.
The structures of the prosapogenins were investigated by (13)C-NMR spectroscopy and Rg (1)-prosapogenin II was shown to be a mixture of ginsenoside Rh (1), and its C-20 epimer, produced by hydrolysis followed by epimerization at C- 20.
Saponins of red ginseng.
From Red Ginseng, all of the known saponins of White Ginseng were isolated in yields similar to those obtained from White Ginseng. Two additional minor saponins, notoginsenoside-R1 (19) (the saponin…
Saponin composition of rhizomes of Panax japonicus collected in South Kyushu, Japan, and its significance in oriental traditional medicine.
The present isolation of the major dammarane-saponins of Ginseng roots from "Satsumaninjin"in relatively high yields is significant not only from the viewpoint of the geographical relation of Japanese P. japonicus with Chinese and Himalayan Panax spp.
Studies on the Saponins of Ginseng. I. Structures of Ginsenoside-Ro, -Rb1, -Rb2, -Rc and -Rd
The saponins of Ginseng root (root of Panax ginseng C. A. japonicum HARA) and P. MEYER have been isolated and the structures have been established as I, II, III, IV, and V.
