Abstract

Compositions comprising extracts or isolated or purified compounds from plants of the genus Corydalis provide prevention and treatment of hyperlipidemia, hypercholesterolemia, hypertriglyceridemia, hepatic steatosis, and metabolic syndrome. Corydalis compounds and their derivatives of natural and synthetic origins lower total cholesterol, LDL-cholesterol, and triglycerides and increase hepatic LDL receptor expression and activate AMP-activated protein kinase. Specific stereoisomers of Corydalis compounds with lipid lowering activity include 14R-(+)-corypalmine, 14R,13S-(+)-corydaline, 14R-(+)-tetrahydropalmatin, (+)-corlumidin, d-(+)-bicuculline, and (+)-egenine.
