ABSTRACT
Cassia tora Linn. (Caesalpinaceae) is a semi-wild annual herb grown widely in different places of south-east Asia including India, Northern Australia and Americas. This plant species is well known for having potential in traditional medicine practices for the treatment of a variety of disorders and ailments ranging from simple cough, hypertension to diabetes. Recent scientific investigation reveals its phytochemical as well as biological potential. C. tora has been proven to be medicinally effective for having antimicrobial, antiantioxidant, antihypertensive, antidiabetic and antimutagenic activities, just to name a few. This paper encompasses a comprehensive review on phytochemical and biological aspects of Cassia tora L.
ABSTRACT
A new compound E was isolated from the methanolic extract of the leaves of Heliotropium indicum by chromatographic fractionation. In the present study, the effect of the compound E on reproduction of Helopeltis theivora has been evaluated. The acute toxicity study (LD50) and sub-acute toxicity studies (haematological, biochemical and histopathological parameters) in albino Swiss mice were carried out to evaluate the safety aspect of the compound E. The compound showed significant inhibitory effect on the reproductive life of H. theivora. The oviposition period, fecundity and hatching percentage of H. theivora were found to be 15.67days, 39.33 and 28.00 % respectively after treatment with 2% compound E, whereas the control value were found to be 20.33 days, 77.67 and 77.33% respectively. The LD50 of the compound was found to be 780 mg kg-1 in Swiss albino female mice. The compound did not show any toxicity in mice at sub-lethal dose treatment (78 mg kg-1 b. wt., once daily) for 21 days as evident from different haematological, biochemical and histopathological parameters in compound E treated group when compared with control.
