Abstract
Kainth fruit, as traditional medicine, has been used in the Himalayan region for its health-promoting properties. However, the phytochemicals and lipidomes of Kainth Seed Oil (KSO) are still scarce. Here, we investigated the physicochemical characterization of KSO and its nutraceuticals, antioxidant potentials. Kainth seeds contain 19–20% oil rich in polyunsaturated fatty acids (PUFA, 82.22%), particularly linoleic acid (C18:2). Lipidome analysis of KSO using high-resolution mass spectrometry showed that trilinoleate (C54:6) was the dominant triacylglycerol (TAG) species. Further, the characteristics of PUFA-rich oil were validated by Fourier transforms infrared spectroscopy (FTIR) and Differential Scanning calorimetry (DSC). The nutraceuticals profiling of KSO depicted the presence of tocopherols (86.72 mg) and phytosterols (32.25 mg) in 100 g oil with significant antioxidant activity. The oil cake contained 19.09% protein and minerals and can be a source for dietary protein. Collectively these results suggest that KSO will be a suitable source for PUFA and nutraceuticals potential.
