我想开个证明，但是不知道是否别检索，劳驾虫友查阅：High-purity isolation of trans-resveratrol from Rhizma Polygoni Cuspidati by high-speed counter-current chromatography Jianchao Deng, Laihao Li, Xianqing Yang, Suping Lu, Yanyan Wu，Shuxian Hao and Bo Qi |

Volume: 690 693 Monograph title: Materials Design, Processing and Applications Issue date: 2013 Publication year: 2013 Pages: 1335-1339 Language: English ISSN: 10226680 ISBN-13: 9783037856925 Document type: Conference article (CA) Conference name: 4th International Conference on Manufacturing Science and Engineering, ICMSE 2013 Conference date: March 30, 2013 - March 31, 2013 Conference location: Dalian, China Conference code: 97228 Sponsor: Northeastern University, China; Harbin Institute of Technology; Jilin University Publisher: Trans Tech Publications Ltd, Kreuzstrasse 10, Zurich-Durnten, CH-8635, Switzerland Abstract: In this paper, high-speed counter-current chromatography (HSCCC) was established and successfully applied for the separation and purification of trans-resveratrol from Rhizma Polygoni Cuspidati. After extracted by microwave assisted extraction (MAE), the dry extract was directly dissolved in HSCCC solvent and introduced to HSCCC separation system. Two-phase solvent system of HSCCC was optimized. Trans-resveratrol was separated from extract of Rhizma Polygoni Cuspidati by high-speed counter-current chromatography in two-step using two different solvent systems composed of chloroform-methanol-water (4:3:2, v/v/v) and n-hexane-ethyl acetate-methanol-water (3:5:4:6, v/v/v/v). From 200 mg of crude extract, 2.5 mg of trans-resveratrol was obtained at over 99% purity by HPLC analyses, and its chemical structure was identified by ESI-MS, 1H NMR. © (2013) Trans Tech Publications, Switzerland.
