Cycloastragenol

Description

Cycloastragenol is the genuine sapogenin of astragaloside IV, a major bioactive constituent of the Chineseherbal medicine Astragali Radix (Huang-Qi). Astragaloside IV exhibits various pharmacological properties, suchas anti-viral, anti-inflammatory, anti-aging,and antioxidant activities.Cycloastragenol is a telomerase activator,which delays the onset of cellularaging. Thus, cycloastragenol is considered as a newgeneration of anti-aging agent.

The Uses of Cycloastragenol

Cycloastragenol is a saponin and aglycone in Astragalus, which are natural triterpenoids.

Preparation

The cycloastragenol was prepared by acid hydrolysis, and the oxidation reaction was carried out before the hydrolysis. The technological process is: oxidation-reduction-hydrolysis-extraction.

Benefits

Cycloastragenol has a steroidal skeleton of tetracyclic triterpene and possess diverse pharmacological activities such as anti-aging, anti-inflammatory, anti-fibrosis, pro-wound healing, liver protection and endothelial protection.
A comprehensive review of cycloastragenol: Biological activity, mechanism of action and structural modifications

Biological Activity

Cycloastragenol(78574-94-4), a natural tetracyclic triterpenoid, was first identified when screening Astragalus membranaceus extracts for active ingredients with antiaging properties. IC50 value:Target:In vitro: In the study of Cycloastragenolon the treatment of degenerative diseases, the result showed that first-pass intestinal metabolism of cycloastragenol might occur upon passage through the intestinal epithelium. Cycloastragenol underwent extensive metabolism in rat and human liver microsomes with only 17.4% and 8.2%, respectively, of the starting amount of Cycloastragenol remaining after 30 min of incubation [1]. The present study demonstrates that cycloastragenol stimulates telomerase activity and cell proliferation in human neonatal keratinocytes. In particular, cycloastragenol promotes scratch wound closure of human neonatal keratinocyte monolayers in vitro [3]. In vivo: Rats were treated with Cycloastragenol (40 mg·kg- 1·d- 1) for 7 days to induce hepatic microsomal enzyme. The result showed that compared with the control, cycloastragenol obviously activated CYP2E1, and remarkably inhibited CYP3A4 [2].

Source

Cycloastragenol is isolated from Astragalus species.

Dosage

As a dietary supplement, take one 100mg capsule of Cycloastragenol daily.
