Syzygium leaves Kenny component of the Tannins
AbstractKen's Syzygium, (Syzygium cumini (L) Skeels) is Rhodomyrtus Section (Myrtaceae) plants for evergreen broadleaf
Leaf trees, mainly distributed in Yunnan, Guangdong and Taiwan.
According to literature, Ken's Pro Syzygium fruits, seeds, flowers and leaves are available for medicinal purposes, and contains abundant tannin,
In recent years, the clinical study Tannins considerable progress, both in chemistry, the discovery of new synthetic compounds or to
Pharmacological study of the results are brilliant. Taiwan is located in the subtropical island, abundant plant resources for
Tannins in plants in Taiwan with the resources to conduct this
research, so this research focuses on Ken's Po leaf tannin content for a
Systematic component analysis, through a variety of column chromatography for separation and purification of 11 kinds of ingredients,
By spectral analysis and chemical reactions, were identified as:
Gallic acid (SC-1), Methyl gallate (SC-2), 6-O-galloyl-β-D-glucose (SC-3), 3
-Methoxy-4-hydroxyphenol lO-β-D-(6-O-galloyl)-gluco-pyranoside (SC-4), B-
ergenin (SC-5), 6-O-galloylbergenin (SC-6), 6-O-galloylnorbergenin (SC-7), 2?
A3-hexahydroxydiphemoyl (HHDP)-D-glucose (SC-8), Castalin (SC -9), Casuariin (
SC-10), Gallocatechin (SC-11).
