Abstract

This study reports analyses of flavonoid profile, anthocyanin, sugar, carotenoid and vitamin compositions in Lonchocarpus sericeus (L. sericeus) seeds. Flavonoid profile, anthocyanin, sugar, carotenoid were determined with gas chromatography coupled with flame ionization detector (GC-FID) while vitamins were determined using pulse flame photometric detector (GC-PTPD). Total flavonoid concentration of L. sericeus seeds was 815.86 mg/100g and its profile consists of flavonol (72.5 %), flavanones (19.3 %), flavones (7.25 %), flavanol (0.93 %) and isoflavones (0.02 %). Quercetin was the most abundant with 28.8 %. L. sericeus seeds composed of 80.5 % disaccharides and 19.5 % monosaccharide with sucrose having 80.4 % abundance. Total vitamin, carotenoid and anthocyanin contents of the seeds were 70.32 mg/100g, 102.18 μg/100g and 12.18mg/100g respectively. Vitamin E (33.3 %), β-carotene (65.4 %) and cyanin (30.3 %) had highest abundance in vitamins, carotenoids and anthocyanins respectively. These results show that the seeds of L. sericeus have intrinsic sweetness and can scavenge for free radicals.
