Five new oleanane-type triterpene saponins including steganogenin 3-O-β-D-glucopyranoside (1), steganogenin 3-O-α-L-rhamnopyranosyl-(1→2)-β-D-glucopyranoside (2), steganogenin 3-O-β-D-glucopyranosyl-(1→2)-β-D-glucopyranoside (3), chichipegenin 3-O-α-L-rhamnopyranosyl-(1→2)-β-D-glucopyranoside (4) and chichipegenin 3-O-β-D-glucopyranosyl-(1→2)-β-D-glucopyranoside (5), along with four known olean...

Background: Hydrocotyle asiatica has a therapeutic significance in the Indian system of medicine due to its rich antioxidant activity. In Homoeopathy, is used for treatment jaundice, skin diseases, dropsy, elephantiasis, leprosy, gonorrhea, leucorrhea, and nervous debility. It contains abundant triterpene glycoside Asiatic acid which shows cytotoxic activity on cancer cells. Its homoeopathic mo...

Background: Morinda umbellata L., commonly called as ‘Manjanatti Kodi’ in Tamilnadu, India, is a rare traditional medicinal plant. The study was aimed to investigate the antioxidant potentiality, phytochemical profiling and elemental mineral analysis of M. leaves. Materials Methods: Antioxidant activity estimated for hexane, chloroform, ethyl acetate, ethanol, methanol aqueous leaf extracts by ...

Spatial patchiness and temporal variability in water availability are common in nature under global climate change, which can remarkably influence adaptive responses of clonal plants, i.e. clonal integration (translocating resources between connected ramets). However, little is known about the effects of spatial patchiness and temporal heterogeneity in water on growth and clonal integration bet...

Nucleon sea structure functions are studied using Dokshitzer-Gribov-Lipatov-AltarelliParisi (DGLAP) equations with the massive gluon-quark splitting kernels for strange and charm quarks, the massless gluon-quark splitting kernels for up and down quarks, and the massless kernels for all other splitting parts. The SU(2)f flavor symmetry for two light quarks, ‘up’ and ‘down’, is assumed. Glück-Rey...

Four known compounds have been isolated from the aerial parts of the Brazilian medicinal plant Pariparoba (Pothomorphe umbellata). They were an alkaloid, a flavone, a dihydrocalcone, and a steroid. The chemical structures were established to be N-benzoylmescaline, wogonin, uvangoletin, and beta-sitosterol glucoside using spectral methods. Among these compounds, the main component N-benzoylmesca...
