Abstract


Department of fragrant fruit trees (Emmenopterys henryi Oliv) Rubiaceae (Rubiaceae) the fragrant fruit tree is (Emmenopterys Oliv) plants, according to the Flora of China, \one kind, that fragrant fruit trees. Fragrant fruit trees in our country are mainly distributed in southwest China and the Yangtze River Basin is a large deciduous trees, flowers white or yellow, in gardens as ornamentals. In folk, roots and bark of the fragrant fruit trees after processed concocted as herbs, warm in and the stomach, Jiangni antiemetic efficacy. The subject stems collected from Jiangxi Jiujiang Lushan fragrant fruit trees as the research object, using silica gel column chromatography, Sephadex LH-20, ODS, semi-preparative HPLC column chromatography, preparative thin-layer chromatography and preparative HPLC separation technology, from which separation 42 compounds, the use of spectroscopy, including IR, EI-MS, ESI-MS, 1H-NMR, 13C-NMR, 2D-NMR, etc. Identification of the Compound 38, compound type involves alkaloids, iridoid glycosides, coumarins, lignin, triterpenoids, steroidal, etc., which have three new compounds (xgs-1 xgs-11 and xgs-38). Specific compounds are as follows: xgs-1: 4 - methyl-5 - oxo-isobutyl the the strictosidine glycosides xgs-2: 5 - oxo different strictosidine the glycosides xgs-3: Loganin. Xgs-4: Strychnos the acid xgs-5: 6'-O-β-D-celery sugar sweroside of xgs-6: sweroside xgs-7: 7 - methoxy base sweroside xgs-8: 7 - O-caffeoyl off horse money alcohol acid XGS-9: smelly vector dishes prime D xgs-10: 6'-O-β-D-celery sugar cichoriin xgs-11: 8-O-(6'-O-β-D-the celery sugar-β- D-glucose) -6 - methoxy-7 - hydroxycoumarin XGS-12: 6'-O-β-D-celery sugar glycosides XGS scopolamine-13: 6'-O-of β-the D-rhamnose sugar scopolamine glycosides xgs-14: scopolamine glycosides xgs 15: fraxin xgs - 16: scopoletin xgs-17: trans-caffeic acid 4-O-6'-O-(3 \the XGS-yl-4 \: Balanophora Ning xgs-21: () - the South candle wood resin phenol-3α-O-β-D-glucoside xgs 22: (-) - South candle wood resin phenol-3α-O-β-D-glucose glycosides XGS-23: () - South candle wood resin phenol-3α-O-9-(3,5 - dimethoxy-4 - hydroxy-benzoyl)-beta-D-glucosidase xgs-24: 3, 4,5 - trimethoxy methoxyphenol-O-of β-D-celery sugar - (1 → 6)-O-β-D-glucoside xgs - 25: iso asphalt acid xgs-26: 13 - Table tar acid xgs- 27: the mountain willow the acid xgs-28,: slope die acid xgs-29: Bear the AHA xgs-30: ursolic acid acetate the xgs-31: taraxerol xgs-32: 6β-hydroxy the sitosterol -4 - ene - 3 - one XGS-33: β-sitosterol XGS-34: sitosterol -4 - ene - 3 - one XGS-35: 3 - hydroxymethyl-4 - vinyl-hexyl-1 ,6 - diol XGS-36 : the sucrose xgs-37: stearic xgs-38: 3 - methoxy-4 - methyl -5,6 - dioxo to different Strictosidine glycosides tetrazolium salt (Methyl-Thiazol-Tetrozolium, MTT) reduction screened a total extract of fragrant fruit trees and two polar fractions, and some of the compounds were A549 (human lung cancer cells), COLO-205 (human colon cancer cells), QGY-7703 (human hepatoma cells), THP-1 ( human monocyte) and the like of tumor cell proliferation inhibition in vitro experiments and found that the part of the n-butanol portion from the three dollops of the compound (xgs-1, xgs-2, xgs-38) having a certain degree of cytotoxic activity. total extract and two polar fractions and compounds were carried out anti NO production role experiment found that the total extract, n-butanol site and two compounds (xgs-9 xgs-11) has a certain anti-inflammatory activity .
