Purple sweet potato color attenuates D-galactose-induced renal injury in mice by inhibiting the expression of NF-κB-dependent inflammatory genes
This study was carried out to investigate the protective effect of purple sweet potato color (PSPC) against D-galactose (D-gal)-induced renal injury and the possible mechanisms in mice. Histopathological analysis showed PSPC could significantly attenuate renal injury induced by D-gal. We found the protective effect of PSPC against D-gal induced renal injury might be caused, at least in part, by renewing the activity of...

Anti-proliferation and anti-migration activities of ten selected Zingiberaceae species against MDA-MB-231 cells
Zingiberaceae plants exhibit various biological activities, but scientific knowledge of the plants in anti-metastatic aspects is still very limited. The objective of this study is to examine the anti-metastatic potentials of 30 crude extracts from ten selected localZingiberaceae species on hormone-independent, highly metastatic human breast cancer cells, MDA-MB-231. The Zingiberaceae rhizomes were...

Phytochemical screening, antioxidant and analgesic activities of Croton argyratus ethanolic extracts
Series of experiments were conducted to screen phytochemical constituents, antioxidant and analgesic activities of the ethanolic extracts of the plant Croton argyratus. The extracts obtained from leaves, stem and root of the plant were evaluated for their antioxidant activity by means of 2,2- Diphenyl -1-picrylhydrazyl (DPPH) radical scavenging activity, reducing power and total antioxidant capacity as well as...

Studies on the protective effects of pollen-originated phytoestrogens on the growth and development of ovary in rats
This present study was undertaken to investigate the effects of pollen extracts on the development of ovary in the presence of exogenous estradiol benzoate. 45-day old female Wistar rats were administered with estradiol benzoate to induce the pathological status of the ovary. Histological observation of ovarian paraffin sections revealed that interruption of the maturation of follicles was associated with massive...

Phytochemical screening and antibacterial activity of four Cnidoscolus species (Euphorbiaceae) against standard strains and clinical isolates
The aim of this study is to investigate phytochemical composition and antibacterial activity of four species of Cnidoscolus [Cnidoscolus infestus Pax and K. Hoffman, Cnidoscolus pubescens Pohl, Cnidoscolus quercifolius Pohl and Cnidoscolus urens (L.) Arthur] used as ethnopharmacologicals in Caatinga. The qualitative phytochemical composition was analyzed by thin layer...

Artabotryside A, a constituent from Descurainia sophia (L.) induces cell death in U87 glioma cells through apoptosis and cell cycle arrest at G2/M phase
Descurainia sophia (L.) commonly known as Webb ex Prantl (flixweed) is a Chinese traditional medicinal plant. Seeds of flixweed are used in the treatment of some cancers. However, the anticancer constituents from the seeds have not been investigated. The present study was aimed to identify bioactive compound with anti-glioma activity from the seeds of D. sophia (L.) and to examine the growth inhibitory...

The effect of Hypericum perforatum extract on the properties of erythrocyte membrane
The phylogenetic relationships of five Atractylodes species were examined by random amplification of polymorphic DNA (RAPD) assay. A total of 298 bands were amplified by 24 RAPD primers, of which 244 bands (81.88%) were polymorphic. The results indicated that: 1) Atractylodes chinensis had a close genetic relationship with Atractylodes lancea, and A. chinensis should be treated...

Cholinesterase inhibitory activities of xanthones from Anaxagorea luzonensis A. Gray
Five xanthones (1-5) were isolated from the heartwood of Anaxagorea luzonensis A. Gray (Annonaceae) and this is the first report of the isolation of xanthone 1 (6-deoxyisojacareubin) from this species. The in vitro inhibitory activity against acetylcholinesterase (AChE) and butyrylcholinesterase (BChE) of these isolated xanthones was highest in 1,3,5-trihydroxy-4-prenylxanthone (3) for both enzymes...
