Abstract
A new arylnaphthalide lignan, corniculin (1), was isolated from 75% EtOH extract of Oxalis corniculata. Its chemical structure was determined by mass spectrometric analysis as well as 1D and 2D nuc...

Oxalis corniculata is a common medicinal plant widely used against numerous infectious diseases. The agrochemical potential of methanolic extract, n-hexane, chloroform, ethyl acetate, and n-butanol fractions were assessed to measure the antibacterial, antifungal, and insecticidal activities of the plant. The crude, chloroform, and n-butanol soluble fractions showed excellent activities against Escherichia coli, Shigella dysenteriae, Salmonella typhi, and Bacillus subtilis but have no activity ag...

Casuarina equisetifolia (L.) (Casuarinaceae) and Oxalis corniculata (L.) (Oxalidaceae), two medicinal plants used in Benin were screened for their antifungal activity against six strains of the genus Aspergillus (Aspergillus fumigatus, Aspergillus flavus, Aspergillus terreus, Aspergillus parasiticus, Aspergillus ochraceus and Aspergillus nidulans). The antioxidant activity and phytochemical constituents were also examined. The extracts were screened for the presence of alkaloids, coumarin, anthr...

Oxalis corniculata L. (creeping wood sorrel) is medicinally important member of family Oxalidaceae, and is distributed in the tropical and subtropical regions of the world. It has been used in different systems of traditional medications for different diseases. Corniculatin A, a new flavonoid glucoside, was isolated from the ethyl acetate soluble fraction of the whole plant along with luteolin, luteolin-7-O-β-D-glucoside and β-sitosterol-3-O-β-D-glucoside, This is the first report of these compo...

The present study was carried out to evaluate the hepatoprotective activity of aqueous and ethanolic leaves extracts of Oxalis corniculata L., Oxalidaceae, against thioacetamide-induced hepatotoxicity. Hepatotoxicity was induced in Wistar rats of either sex by subcutaneous injection of thioacetamide. An aqueous and ethanolic extract of aerial parts of O. corniculata (200 and 400 mg/kg/day) were evaluated. Oral administration of O. corniculata aqueous and ethanolic leaves extract at 400 mg/kg res...

A careful investigation of the subterranean part of Vitex rotundifolia has shown that this plant contains five novel lignans having a 1-phenylnaphthalene-type skeleton together with four known lignans. These structures were elucidated on the basis of spectroscopic data. Furthermore, some of the isolated compounds showed antibacterial activity against methicillin-resistant Staphylococcus aureus (MRSA).
