Exposure to environmental pollutants often leads to an upsurge in the production of reactive oxygen species (ROS). ROS oxidize cellular fatty acids to produce lipid peroxyl radicals, subsequently transformed into lipid peroxides, which decrease membrane fluidity and increase the activity of various

Following an ethnobotanical search carried out in Guinea-Bissau, eighteen extracts derived from sixteen medicinal species were screened for antimicrobial, antitumor and antileishmania activity. Significant antitumor activity was found for Holarrhena floribunda against KB (squamous carcinoma), SK-Mel

In the present study, we have experimentally and theoretically studied the free-radical quenching property of dihydrocanaric acid (DCA) isolated from seedpods of Holarrhena antidysenterica. A modified method was used to estimate the nitric oxide scavenging effect of the DCA (significant

Methanolic extracts of Acorus calamus (Rhizome), Hemidesmus indicus (Stem), Holarrhena antidysenterica (Bark) and Plumbago zeylanica (Root), were tested for their antimutagenic potential. These extracts, at tested concentrations, showed no sign of mutagenicity to Salmonella typhimurium tester

In vitro cytotoxic potential of extracts (95% and 50% ethanolic extract and hot water extract at concentration of 100 microg/ml) from leaves of Holarrhena antidysenterica was evaluated against fourteen human cancer cell lines--A-549, COLO-205, DU-145, HeLa, HEP-2, IMR-32, KB, MCF-7, NCI-H23,

A novel triterpenoid, holarol(1),3β-lup-20(31)-en-3,29,30-triol along with one seco-triterpenoid, dihydrocanaric acid(2) and one known pentacyclic triterpenoid, betulin(3) have been isolated from Holarrhena antidysenterica (L.)Wall. (Family: Apocynaceae).
