Twelve methanolic plant extracts from botanical species used in traditional medicine in Morelos, México to cure infectious diseases have been subjected to a screening study to detect potential antimicrobial activity against Staphylococcus aureus, Escherichia coli, Pseudomonas aeruginosa and Candida albicans. The antimicrobial activity of the products was(More)
AIM OF THE STUDY This review provides a summary of Mexican medicinal flora in terms of ethnobotanical, pharmacology, and chemistry of natural products related to anticancer activity. MATERIALS AND METHODS Bibliographic investigation was carried out by analyzing recognized books and peer-reviewed papers, consulting worldwide accepted scientific databases(More)
From the stem bark of Mangifera indica, seven cycloartane-type secondary metabolites were isolated. Compound 1 has been isolated for the first time from M. indica, whereas compounds 2 (2a and 2b, as an epimeric mixture), 3, and 4 are new triterpenoid-type cycloartanes. Unambiguous (13) C and (1) H NMR assignments for these compounds and the known compounds(More)
Crude extracts from nine plants widely used in Mexican traditional medicine for the treatment of cancer have been subjected to a bioscreening study to detect cytotoxic activity against human tumor cells. Three different extracts (petroleum ether, ethylacetate, and methanol) from each plant species, were tested towards KB, HCT-15 COLADCAR and UISO-SQC-1 cell(More)
A tissue culture method is described for callus formation from Galphimia glauca (Mapighiaceae) in MS (Murashige & Skoog) medium supplemented with various growth regulators. Best induction was achieved when using hypocotyls as explants in medium supplemented with 2 mg/l of 2,4-dichlorophenoxyacetic acid (2,4-D). Major cellular growth of calluses was obtained(More)
Galphimia glauca is popularly employed in Mexico for the treatment of central nervous system disorders. Pharmacological and phytochemical studies have resulted in the identification of the anxiolytic and sedative principle consisting of a mixture of nor-secofriedelanes, named the galphimine series (1 - 9). These active constituents were found in plants(More)
The hydroalcoholic extract of the steam bark of B. fagaroides var. fagaroides displayed potent cytotoxic activity against four cancer cell lines, namely KB (ED50 = 9.6 × 10(-2) μg/mL), PC-3 (ED50 = 2.5 × 10(-1) μg/mL), MCF-7 (ED50 = 6.6 μg/mL), and HF-6 (ED50 = 7.1 × 10(-3) μg/mL). This extract also showed anti-tumour activity when assayed on mice(More)
Biological assays of Vitex trifolia L. organic extracts have shown relevant activities. Hexanic and dichloromethanic (DCM) extracts, when prepared from stems and foliage, have proved to be very toxic against several cancer cell lines in culture (SQC-1 UISO, OVCAR-5, HCT-15 COLADCAR, and KB). Also, an important antifeeding activity against the insect pest(More)
ETHNOPHARMACOLOGICAL RELEVANCE Castilleja tenuiflora Benth. (Orobanchaceae) is a perennial shrub used since the 16(th) century in Mexican traditional medicine for the treatment of a number of health disorders including inflammation, stomach pain and tumors. The aim of the present study was to evaluate the cytotoxic, anti-inflammatory and anti-ulcerogenic(More)
