Morphophysiology of indigenous vegetable Sintrong (Crassocephalum crepidiodes) from several areas in West Java

Abstract

Sintrong (Crassocephalum repidiodes) is an indigenous vegetable in several regions in Indonesia. It is nutritious and contains bioactive ingredients that are beneficial to health. Although it has been consumed as a vegetable, it has not been cultivated so people only harvest it from nature. The study aimed to obtain information about its morphological and physiological characteristics to develop cultivation technology. In situ exploration was conducted in three areas namely Bogor, Cianjur, and Purwakarta in the highlands and lowlands. Observations were made on morphological and physiological characters, namely leaf characters, pigment content, flavonoids, and phenol content. The results showed that there were 4 accession groups based on morphophysiological characters. In addition, all accessions showed that they contained beneficial non-nutritive chemical components, namely flavonoids in the range of 1152.39-1596.15 mg QE 100 g−1 dry matter and total phenol 722.96-2345.97 mg GAE 100 g−1 dry matter.
