Bioassay-guided fractionation of the cytotoxic MeOH extract obtained from Acridocarpus vivy led to the isolation of five new triterpenoids, acridocarpusic acids A-E (1-5); three known triterpenoids, moronic acid (6), ursolic acid, and oleanolic acid; and two known flavonoids, 4',5-dihydroxy-7-methoxyflavone and 4',5-dihydroxy-3',7-dimethoxyflavone. The structures of the new compounds 1-5 were established on the basis of extensive 1D and 2D NMR spectroscopic data interpretation. Compound 3… 
Anti-protozoal and structure-activity relationships of chemical constituents of Acridocarpus chloropterus Oliver (Malpighiaceae) from Tanzania
The strong to moderate anti-leishmanial activity of the isolated triterpenes and flavonoids make them good candidates or templates for new anti-protozoal drug development.
Chemical Constituents of Acridocarpus orientalis and Their Chemotaxonomic Significance
Acridocarpus orientalis (Malpighiaceae) consists of 30 species, with 11 widely distributed in Africa, six in Madagascar, and a single species in New Caledonia [1–3]. It is mainly used in Oman and UAE
Differential Cytotoxic Potential of Acridocarpus orientalis Leaf and Stem Extracts with the Ability to Induce Multiple Cell Death Pathways
Variable potential to induce cell death in cancer cells via apoptotic and non-apoptotic pathways is revealed, making A. orientalis a valuable plant for the exploration of anticancer bioactive reagents, some of which may be protective for normal cells.
Chemical constituents of the hemiparasitic plant Phoradendron brachystachyum DC Nutt (Viscaceae)
In this chemical study, morolic acid was isolated as the major component (47.54% of the total composition of acetone extract) of Voradendron brachystachyum and 19 known compounds were identified.
Antioxidant activities of Lampaya medicinalis extracts and their main chemical constituents
It can be concluded that L.medicinalis can be used as an effective natural source of antioxidant, as ethnomedicine and as a commercial basis for the development of nutraceuticals.
