Research articles related to koshataki:
Anti- diabetic and Anti -hyperlipidemic activity:  The extracts of the plant were screened for in vitro anti-oxidant activity. The effect of different extracts of LA in the management of diabetes and related complications were determined. The study revealed that the methnolic extract at a dose of 100mg/kg was found to be active for anti- diabetic activity and anti- hyperlipidemic activity.

Anti- cancer activity: In vitro studies were carried out to evaluate the cytotoxic potential of the ethanolic and aqueous extracts ofLuffa acutangula against human neuronal glioblastoma cells (U343) and human lung cancer cells (A549). Screening of these extracts was done using the brine shrimp lethality bioassay, MTT assay and SRB assay. The results showed the significant decrease of the viability of the cells in a concentration-dependent manner. The ethanolic and aqueous extracts of Luffa acutangula showed significant cytotoxic activity in both MTT and SRB assay. In brine shrimp lethality bioassay also aqueous extract showed more potent cytotoxicity as compared to ethanolic extract.

Anti- oxygenic activity: Ridge gourd pulp and peel powders as well as their various solvent fractions were evaluated for antioxygenic activity using different methods. Ridge gourd pulp and peel powders as well as their extracts were evaluated for their antioxygenic activity using linoleic acid peroxidation, β-carotene-linoleic acid bleaching and 1,1-diphenyl-2-picryl-hydrazyl (DPPH) methods. Ethanol/water extracts from ridge gourd pulp and peel showed highest antioxygenic activity followed by water extracts, while the petroleum ether extract showed moderate antioxygenic activity. Ridge gourd peel powder and its extracts showed slightly higher antioxygenic activity than ridge gourd pulp powder and its extracts. This may be attributed to the presence of higher amounts of phenolics and flavonoids which have been reported as potential antioxidants.
