General Description

Oleanolic acid 3-acetate is a chemical compound belonging to the class of organic compounds known as triterpenoids. It is a derivative of oleanolic acid, which is naturally found in plants belonging to the Oleaceae family. It is known for its beneficial bioactive properties such as hepatoprotective, anti-inflammatory, antioxidant, antitumor, and antiviral activities. Oleanolic acid 3-acetate is typically used in various traditional medicines and can even be extracted for use in pharmaceutical products. Despite its potential benefits, it is important to note that the substance should not be ingested or used without professional medical advice, as excessive dosages can potentially lead to complications and side effects.

SELECTIVE CLEAVAGE OF ESTER TYPE GLYCOSIDE-LINKAGES AND ITS APPLICATION TO STRUCTURE DETERMINATION OF NATURAL OLIGOGLYCOSIDES

On treatment with anhydrous LiI, 2,6-lutidine and anhydrous methanol, an ester type glycosyl linkage of acidic tri- and di-terpenes was selectively cleaved without decomposition of a reducing terminal of the resulting sugar moiety to give an anomeric mixture of methyl glycosides along with an aglycone or a pro-aglycone in quantitative yield.In this reaction, no hydrolysis of any other glycoside linkages took place.
