MORPHOLOGICAL, ANATOMICAL CHARACTERISTICS AND PHOTOCHEMICALS OF BITTER LEAF HARVESTED IN THAI NGUYEN

Abstract

“Bitter leaf” are mostly consumed in Asia and Africa, due to its potential as a good source of antidiabets. In this study, the bitter leaf in Thai Nguyen province has been described in morphological, anatomical characteristics and primarily identified as Vernonia amygdalina Del., Asteraceae. Carrying usual chemistry reactions, we found some groups of photochemicals of Vernonia amygdalina Del., such as flavoniods, saponins, tannins and reducing sugars.
