Tectorigenin Chemical Properties,Usage,Production

Description

Tectorigenin is an isoflavone that exists in numerous plant resources, and it is especially abundant in Belamcandae Rhizoma and Puerariae flos, which both have the effects of clearing away heat, removing toxic substances, relieving sore throat, and reducing swelling. As one of the most important active ingredients, the pharmacological effects of tectorigenin have been demonstrated by an increasing number of investigators. Due to its extensive pharmacological activities, including anticancer, antioxidation, hepatoprotection, anti-inflammation, etc., tectorigenin has received a large amount of attention[1].

Occurrence

Tectorigenin, a methoxy isoflavone with three hydroxyl groups, is chemically noted as 5,7-dihydroxy-3-(4-hydroxyphenyl)-6-methoxy-4H-chromen-4-one. As a bioactive compound, tectorigenin is found in several plant species, most notably in the rhizomes of Belamcanda chinensis (L.) DC., a traditional Chinese medicine (TCM) named Belamcandae Rhizoma. The Iris family is the major source of tectorigenin, and many Iridaceous plants, such as Iris spuria L. (Calizona), Iris tectorum Maxim, Iris japonica Thunb., Iris dichotoma Pall., Iris germanica L., Iris unguicularis Poiret, Iris loczyi Kan., Iris kashmiriana Baker, Iris crocea Jacq. ex R. C. Foster, Iris ensata Thunb., Iris germanica L., Iris hungarica Waldst. et Kit., Iris confusa Sealy, and Iris pseudacorus L. contain abundant tectorigenin, so tectorigenin is also known as iris flavone. Tectorigenin also exists in some leguminous plants, such as the flowers of Pueraria lobata (Willd.) Ohwi, Pueraria thomsonii Benth., and Pueraria thunbergiana Benth. are also TCM called Puerariae Flos. Tectorigenin was isolated from the leaves of Dalbergia odorifera T. Chen, the heartwood of Dalbergia parviflora Roxb., and the roots of Euchresta formosana (Hayata) Ohwi as well. Moreover, some plants in other families also contain tectorigenin, including Codonopsis pilosula (Franch.) Nannf. (Campanulaceae), Morus alba L. (Moraceae), Viola hondoensis W. Becker et H. Boissieu. (Violaceae), and Eleocharis dulcis (Burm. f.) Trin. ex Hensch. (Cyperaceae)[1].

Uses

Tectorigenin is identified as an α-glucosidase inhibitors. Potent lactate dehydrogenase (LDH) inhibitor.
