A major chromatographic peak of anthocyanin from ogaja (Acanthopanax sessiliflorum) fruit represented 95.4% of total absorbable compounds at 518nm. The mass-to-charge ratio (m/z) of this colorant was determined to be 581 by LC–MS, which was identical to the molecular mass of cyanidin-3-O-sambubioside. After acid hydrolysis of the purified anthocyanin fraction, it was structurally confirmed by thin...
The antioxidative activity of Mungoong, an extract paste, from the cephalothorax of white shrimp (Litopenaeus vannamei) was studied. Extraction media were shown to affect the antioxidative activity and properties of resulting extracts from Mungoong. Distilled water exhibited the highest efficacy in extracting the antioxidants from Mungoong, as evidenced by the highest ABTS (2,2-azino-bis(3-ethylbenzothiazoline-6-sulfonic...
