Pharmacognostical, Phytochemical studies and Antibacterial activity of Wood from Talipariti elatum Sw. (Fryxell) in Cuba

Abstract

A preliminary pharmacognostical and phytochemical evaluation of Talipariti elatum (Sw.) that grows in Cubawas realized to determine the macromorphology and micromorphology characteristics, the physicochemical and phytochemical parameters from the wood of this spice that grows in Cuba. This crude drug showed the characteristic physicochemical values such as moisture content (7.6 %), total ashes (1.14%), water soluble ashes (0.19 %), acid insoluble ashes (0.33 %) and extractable matter in ethanol at 70 % (10.87 %). Phytochemical screening revealed the possible presence of triterpenes and/or steroids, reductants sugars, tannins and/or phenolic compounds, flavonoids and bitter and astringent principles, realized under WHO parameters. The antibacterial activity of ethanolic extracts at 30, 50 and 70 % of the wood against Salmonella tiphymurium 14028, Bacillus cereus 11778, Escherichia coli 25922 and Staphylococcus aureus 25923showed varying degrees of inhibition on the tested organisms.
