Analysis of bioactive compounds present in different crude extracts of Benincasa hispida and Cucurbita moschata seeds by gas chromatography-mass spectrometry

Plant seeds are the resources of many different bioactive components. The chemical composition of the different crude extracts from Benincasa hispida (White pumpkin) and Cucurbita moschata (Pumpkin) seeds with three different polarity-based solvents (n-hexane, n-hexane-chloroform (2:1), and methanol) was analyzed to identify the biologically active compounds. Each of the extracts was analyzed by gas chromatography-mass spectrometry. Different extracts of targeted seeds showed different biologically active compounds that have different pharmacological potentialities. 9, 12-Octadecadienoic acid (ZZ) was the most potent bioactive compound present in three different extracts of both B. hispida and C. moschata. Another bioactive compound comparatively low percentage present in both plants was n-hexadecanoic acid. Other major pharmacologically active compounds present in both plants were 9- Octadecenoic acid (Z)-, methyl ester, and 9, 12-Octadecadienoic acid methyl ester (E, E). Besides these compounds, a few more biologically active compounds were present in the two plants separately. The findings of this study support the use of these seeds in modern functional foods, nutraceuticals, and medicinal purposes, and the whole seeds would give better health benefits rather than use any extract. Although further pharmacological examinations should be carried out to conclude the medicinal application of the seeds of these two plants as well as to understand the mechanism of the potential health benefits.
