Carica papaya, a member of the family Caricaceae, is commonly known for its food and nutritional value throughout the world. During last few decades considerable progress has been achieved regarding the biological activity and medicinal application of papaya and now it is considered as valuable neutraceutical fruit plant. The present study was designed to determine the antimutagenic and anticytotoxic activities of different fractions (Aqueous, Chloroform, Ethanol and Ethyl acetate extracts) of Carica papaya leaves. Antimutagenic activity was determined by the Allium cepa root chromosomal assay using Cyclophosphamide monohydrate as the mutagenic agent and anticytotoxic activity of the extracts was evaluated by determination of mitotic index. All the four fractions displayed significant antimutagenic and anticytotoxic activities against cyclophosphamide-induced chromosomal aberrations and alltogether, the results of our study lend pharmacological credence to the anti-cancerous and ethnomedical use of this plant in traditional system of medicine and these results could be used to develop antimutagenic compounds for cancer therapy.

The aim of the present study was to investigate the chemical composition of Spirulina subjected to different solvent extraction (acetone, methanol and ethyl acetate) by using soxhlet methodology and the extracts were analysis by Gas chromatography coupled with mass spectrophotometer (GC-MS) using DB-5 capillary column. During GC-MS analysis, it was observed that fatty acid components are present in their extracts. In acetone extract, totally forty compounds were identified and heptacosane (17.25%), hexacosane (17.04%), heneicosane (14.47%), pentacosane (13.22%) and Nonacosane (11.29%) as major components. Thirty five compounds were identified in methanol extract and the major compounds are n-Hexadecanoic acid (19.9%), Cyclononasiloxane octadeca methyl (7.81%) and phytol (6.53%). Thirty components were identified in ethyl acetate extract and dodecane (17.35%), heptadecane (15.31%), sufurous acid butyl heptadecyl ester (11.31%) and n-hexadecanoic acid (4.26%) most abundant in ethyl acetate extract.
