Product Overview
Oleanolic Acid is a pentacyclic triterpenoid widely distributed in the plant kingdom, first isolated from Olea europaeaand commonly extracted from olive leaf, olive pomace, and Traditional Chinese Medicinal herbs such as Ligustrum lucidum(Nu Zhen Zi). It occurs as a white to off-white crystalline powder, practically insoluble in water, soluble in organic solvents (MeOH, EtOH, DMSO, chloroform).
Our Oleanolic Acid is supplied at ≥98% / ≥99% HPLC (pharma / research grade) and also available as herbal extract standardized 20%–80% for formulation use. It is extensively studied for hepatoprotective, anti-inflammatory, antioxidant, and anti-tumor activities, and increasingly adopted as a botanical active in cosmeceutical formulations (anti-aging, soothing).
