Objective : The genus Tephrosia is a rich source for unusual flavonoids. The present work is aimed to isolate new molecules of biological interest. Materials and methods : The ischolar_main powder of T. procumbens was extracted with chloroform and concentrated. The residue was subjected to column chromatography and fractional crystallization by organic solvents and their mixtures of increasing polarity which afforded crystalline compounds and were identified by spectroscopic methods. Results and conclusions : Among the isolates, two candidates calopogonium isoflavone B and 2', 7' 8-trimethoxy-4' , 5' -methylenedioxy isoflavone are reported for the first time from this species.Keywords

A review of phytoconstituents and biological activities of Cassia species has been presented, considering the fact that there are about 580 species of this genus distributed all around the world. Only 46 species have been studied phytochemically. Hence an attempt is made to present a review on the phytochemical studies of Cassis sepcies which still remains as a potential source for bioactive molecules.Keywords

A review of phytoconstituents and biological activities of Digitalis species has been presented. Despite the fact that there are about 24 species of this genus spread around the world, the present survey revealed that only 17 species have been studied phytochemically. Hence an attempt is made to present a review on the phytochemical studies of Digitalis species which would possibly serve as a source for much potent cardioactive molecules.Keywords
