[About Corosolic Acid];
Corosolic acid is a substance extracted from Lagerstroemia speciosa L. and has been reported to have biological activities in in vitro and experimental animal studies, particularly due to its influence on blood sugar. Thus, corosolic acid may have an influence on diabetes. Corosolic acid is found in many plants, particularly Banaba, but also in loquat leaf, almond hulls, Weigela subsessilis, Perilla frutescens, Campsis grandiflora and other herbs.It is similar in structure to ursolic acid, differing only in the fact that it has a 2-alpha-hydroxy attachment.
