(family Convolvulaceae) is a common wild plant growing in the kingdom of Saudi Arabia. It is used in traditional medicine. Our study resulted in the isolation and structural elucidation of ten natural products from which a stilbene carboxylic acid was isolated for the first time as a new natural product. The isolated products are mainly shikimates in addition to two sterols; beta -sitosterol and stigmasterol, as well as one triterpenoid, oleanolic acid. The shikimate products are vanillin, vanillic acid, syringic acid, ferulic acid, isoferulic acid, isoscopoletin and the new stilbene derivative. The structures were elucidated on the basis of spectral data from 400 MHz H-1 NMR, MS, IR and UV. The biogenesis of the new stilbene is discussed.  Journal Name : PHARMAZIE  Volume : 55  Issue Number : 11  Publishing Year : 2000 AH   Added Date : Tuesday, June 24, 2008  Researchers Researcher Name (Arabic) Researcher Name (English) Researcher Type Dr Grade Email صالح بن طاهر ازمرلي Ezmiriy ST Researcher     Dawidar AM Dawidar AM Researcher     Abdel-Mogib M Abdel-Mogib M Researcher     Ei-Dessouki Y Ei-Dessouki Y Researcher     Angawi RF Angawi RF Researcher     Back To Researches Page
