    Author: Shang XY, Li S, Wang YH, Wang SJ, Yang YC, Shi JG.
    Journal: Zhongguo Zhong Yao Za Zhi; 2006 Dec; 31(23):1953-5. PubMed ID: 17348187.
    Abstract:
    OBJECTIVE: To study the chemical constituents of Bauhinia aurea. METHOD: The compounds were isolated with column chromatography. The structures were determined by MS and NMR spectroscopic techniques. RESULT: Nine aromatic acid derivatives, two triterpenes and three steroids were isolated from the 90% ethanolic extract and their structures were identified as 3,4-di-hydroxybenzoic acid (1), 4-hydroxybenzoic acid (2), 3-hydroxy-4-methoxy-benzoic acid (3), 4-hydroxy-3-methoxybenzoic acid (4) , gallic acid (5) , methyl gallate (6) , ethyl gallate (7) , lupeol (8) , lupenone (9) , stigmast4-en-3-one (10) beta-sitosterol (11) and daucosterol (12). CONCLUSION: This is the first report of chemical constituents from B. aurea. Compounds were isolated from this genus for the first time, except 5,8,11 and 12.
