Abstract

The invention discloses structures of two new compounds deriving from Chinese herbal medicine semen cassiae, and the two compounds are 1-hydroxyl-2-acetyl-3, 8-dimethoxy-6-O-[beta-D-apiofuranosyl-(1-2)-beta-D-glucopyranosyl]-naphthalene (I), and 1-demethylaurantio-obtusin-2-O-beta-D-glucopyranoside (II) respectively. Simultaneously, the invention also discloses an extraction and separation method of the two new compounds, as well as application of their derivatives in preparing active medicaments for antioxidation and liver protection.

Description

technical field [0001] The invention belongs to the field of phytochemistry, specifically belongs to the field of extraction, separation and preparation of active ingredients of traditional Chinese medicines, and in particular relates to the extraction and separation of compounds with pharmacological activity from the seeds of cassia cassia and a method thereof. Background technique [0002] Semen Cassiae (Semen Cassiae) is the dry mature seed of Cassia obtusifo L. or Cassia tora L., a leguminous plant. The chemical composition of cassia seeds is mainly anthraquinones, in addition to benzopyrone, sterols, fatty acids and other components. Modern pharmacological studies have shown that Semen Cassiae has the activities of lowering blood pressure, lowering blood fat, protecting liver and inhibiting bacteria, and is widely used. In addition, cassia seed is a traditional Chinese medicine that can be used as both medicine and food, and is a good raw material in the field of healt...
