The present article describes the isolation and characterization of secondary metabolites from the leaves of Cerbera odollam as well as bioactivities of the crude methanolic extract and its petroleum ether (PE), carbon tetrachloride (CTC), chloroform (CF) and aqueous (AQ) soluble fractions. In this investigation, successive chromatographic separation and purification yielded β-amyrin (CO-01), lupeol (CO-02), β-sitostenone (CO-03) and triticusterol (CO-04). The study also indicated the antioxidant, cytotoxic, antimicrobial, membrane stabilizing activities and poor thrombolytic activities. Thus, the present study endeavors to provide scientific basis to establish Cerbera odollam as a potential medicinal plant.Dhaka Univ. J. Pharm. Sci. 16(2): 179-186, 2017 (December)

Liquid culture fermentations of Fusariumculmorum yield a wide variety of secondary metabolites. In addition to known isoprenoids, such as the trichothecenes and modified trichothecenes, four new derivatives of culmorin have been isolated and characterized by spectral analysis. These compounds are 15-hydroxyculmorone (7), and 5-hydroxy- (8), 12-hydroxy- (10), and 15-hydroxyculmorin (9). The structure of culmorone is confirmed. The biosynthesis of culmorin from farnesyl pyrophosphate is substantiated through the use of 13C-acetate and the oxidation of these derivatives is discussed.

Phytochemical Profile

The present study was intended to discover the preliminary phytochemicals of Dictyota dichotoma (Huds.) Lamouroux from Koothankuzhi coast, Tirunelveli district, the south east coast of Tamil Nadu, India. The preliminary phytochemical analysis was conducted in seven extracts namely methanol, acetone, chloroform, ethyl acetate, petroleum ether, hexane and benzene by Harborne method. The preliminary phytochemical analysis showed the presence of alkaloids, anthocyanin, anthraquinones, cardiac glycosides, catechin, coumarins, diterpenes, emodins, flavonoids, glycosides, leucoanthocyanin, lignins, phenols, phlobatannins, quinones, saponins, steroids, tannins, terpenoids and triterpenoids. Among the various phytochemicals studied, tannin showed the maximum presence, being found in seven different extracts and anthraquinones was observed in only one extract. From the results, it was noted that the extracts of Dictyota dichotoma (Huds.) Lamouroux was found to be the presence of a number of active secondary metabolites. This report will lead to the isolation and characterization of these active secondary metabolites for bioefficacy and bioactivity.
