One new sulfated saponin 3β,23,30-trihydroxyurs-20-en-28-al-23-sulfate 3-O-β-D-xylopyranoside (Zygofaboside C; 1) was purified from the water soluble fraction of ethanolic extract of the aerial parts of Zygophyllum fabago Linn. The structure of the compound was elucidated through spectral studies, especially 1Dand 2D-NMR, HR-FAB mass spectrometry, and comparison with literature data.
Limitations on pollen and resources may significantly affect plant reproduction in fragmented habitats. In this study, phenology and pollinator frequency and activity were investigated to estimate the role of pollinators in Zygophyllum xanthoxylum reproduction, and this species is ecologically important in northwest China. In addition, the relative impact of restrictive amounts of pollen and re...
Two new sulfated triterpenoid saponins, zygophylosides Q (1) and R (2), have been isolated from the barks of Zygophyllum fabago L. Their structures were elucidated as 3beta,24,28,30-tetrahydro-urs-20-ene-24-O-sulphonyl-3-O-[beta-D-glucopyranosyl]-30-O-beta-D-glucopyranoside and 3beta,24,28,30-tetrahydro-urs-20-ene-24-O-sulphonyl-3-O-[beta-D-xylopyranosyl]-30-O-beta-D-glucopyranoside, respective...
receipts", for instance, appear in the same form in learned treatises, manuscript collections of recipes, and in oral tradition. The book ends with a case study in the popular medicine of the time, by looking at women's work as medical practitioners. Nagy illustrates very clearly how women, especially charitable gentlewomen, were not mere nurses but undertook the treatment of the most difficult...
