Title: [Studies on chemical constituents from Eucommia ulmoides Oliv]. Author: Sun Y, Dong J, Wu S. Journal: Zhong Yao Cai; 2004 May; 27(5):341-3. PubMed ID: 15376388. Abstract: OBJECTIVE: To study the chemical constituents from Eucommia ulmoides Oliv. METHODS: The chemical constituents were isolated and repeatedly purified on silica gel column. They were identified and structurally elucidated by means of physio-chemical constants and spectral analysis. RESULTS: Seven compounds were obtained. They were (-)epicatechin (I), catechin (II), n-octacosanoic acid (III), tetracosanoic-2, 3-dihydroxypropylester (IV), rutin (V), chlorogenic acid (VI), and caffeic acid (VII), respectively. CONCLUSION: Four compounds (II, III, IV, V) were isolated from bark of Eucommia ulmoides Oliv for the first time.[Abstract] [Full Text] [Related] [New Search]
