Chemical Constituents from the Buds of Zingiber striolatum.

The buds of I Z. striolatum i were collected in August of 2019 from Guizhou Province of P. R. China and were authenticated by Dr. Daopeng Tan (Pharmacognosy), an associate professor of Zunyi Medical University. In the present study, our further chemical investigation into the constituents of the buds of I Z. striolatum, i nine compounds were isolated and identified previously from this plant. The EtOAc extract (60 g) was subjected to a series of chromatographic methods, such as column chromatography using silica gel (200-300 or 300-400 mesh) and Sephadex LH-20, and yielded compounds B 1-9 b . The buds of I Z. striolatum i contain abundant protein, polysaccharides, amino acids, and trace elements, and serve as a delicious vegetable with high nutritional value [[3]].
