A new antifungal eudesmanolide glycoside 11,13-dihydro-3-O-(β-digitoxopyranose)-7α-hydroxy eudasman-6,12-olide (2) in addition to known compounds 1 and 3, has been isolated from Sphaeranthus indicus Linn. Its structure was determined by spectral analysis (UV, IR, 1D and 2D NMR and mass spectrum).
A series of 61 Indian medicinal plants belonging to 33 different families used in various infectious disorders, were screened for their antimicrobial properties. Screening was carried out at 1000 and 500 microg/ml concentrations by agar dilution method against Bacillus cereus var mycoides, Bacillus
The dichloromethane extract of the air-dried leaves of Sphaeranthus africanus afforded four new carvotanacetone derivatives (1, 2, 3A, and 3B). Their structures were elucidated by extensive 1D and 2D NMR spectroscopy. Compounds 1- 3 exhibited antibacterial activity against Staphylococcus aureus and
The free radical scavenging potential of the plant S. indicus was studied by using different antioxidant models of screening. The ethanolic extract at 1000 microg/ml showed maximum scavenging of the radical cation, 2,2-azinobis-(3-ethylbenzothiazoline-6-sulphonate) (ABTS) observed upto 41.99%
A promising therapeutic approach to reduce pathological inflammation is to inhibit the increased production of pro-inflammatory cytokines (e.g., TNF-alpha, IL-6). In this study, we investigated the anti-inflammatory potential of 7-hydroxyfrullanolide (7HF). 7HF is an orally bioavailable, small
