Flavonoids of Crotalaria sessiliflora.
Phytochemical investigation of the whole plants of Crotalaria sessiliflora L. led to the isolation of four flavonoids. The structures of these compounds were identified as 2',4',5,7-tetrahydroxyisoflavone (1), 2',4',7-trihydroxyisoflavone (2), 4',7-dihydroxyflavone (3), and isovitexin (4) using spectroscopic analysis. Among these, compounds 2, and 3 have not been reported from Crotalaria specie...
متن کاملSynthetic cardenolides and related products.
ABSTRACT Since the publication in 1785 of one of the great classics of clinical medicine, 'An Account of the Foxglove and Some of its Medical Uses' by William Withering', the steroidal glycosides of digitalis have maintained a unique position among drugs. Their usefulness as life saving products is unchallenged and yet very few drugs are known to possess a narrower margin of safety. Their toxic...
متن کاملSterols and Flavonoids of Lomatopodium staurophyllum
Background: The genus Lomatopodium Fisch. & C.A.Mey., belongs to Apiaceae family and contains one herbaceous species growing wildly in Iran. There are only a few papers about the chemical constituents of these plants. Here, we focused on the isolation and identification of the main flavonoid glycosides and sterols from the aerial parts of L. staurophyllum, which has not been previously reported...
متن کاملpostnatal studies of bats (pipistrellus kuhlii and miniopterus schreibersii) & histomorphology and histochemistry studies of organs and diseases of (neurergus microspilotus and n. kaiseri)
1. to determine whether difference in birth body mass influenced growth performance in pipistrellus kuhlii we studied a total of 12 captive-born neonates. bats were assigned to two body mass groups: light birth body mass (lbw: 0.89 ± 0.05, n=8) and heavy birth body mass (hbw: 1.35 ± 0.08, n=4). heavier body mass at birth was associated with rapid postnatal growth (body mass and forearm length) ...
Enteric disposition and recycling of flavonoids and ginkgo flavonoids.
OBJECTIVE The objective of this study was to determine the intestinal and microbial disposition of flavonoids and how these disposition processes affect their enteric recycling. DESIGN Studies were performed using a perfused rat intestinal model or using enrichment cultures and a pure isolate of Enterococcus avium (LY1). RESULTS In the rat intestine, aglycones, such as quercetin and apigeni...
