L rhamnopyranosyl (1→2) ? D glucopyranoside, i e vitexin rhamnoside (Ⅰ), hyperoside (Ⅱ), citric acid (Ⅲ), vitexin (Ⅳ), quercetin (Ⅴ), ursolic acid (Ⅵ) Conclusion Compound Ⅰ is a proprietary constituent in the fruit of C pinnalifida, which was obtained from this plant for the first time Compound Ⅱ is a main constituent with blood lipid reducing effect in flavonoids
