摘要：

From the fruits of Gardenia jasminoides several. carotenoids were isolated and identified. Crocetin (1) was characterized by UV/vis, cochromatography, and LC-MS. The following glycosyl esters of crocetin (1) were identified: crocin (crocetin di(beta-gentiobiosyl) ester) (6) by UV/vis, H-1- and C-13- NMR, and FAB-MS and crocetin mono(beta-gentiobiosyl) ester (4) by UV/vis, H-1-NMR, and LC-MS. There are strong indications for the presence of 13Z-crocin (9) (UV/vis, H-1-NMR, and LC-MS). From saffron (Crocus sativus L.), another glycosyl ester of crocetin (1) was isolated. It was identified as crocetin (beta-gentiobiosyl) (beta-neapolitanosyl) ester (7) by UV/vis, H-1-NMR, and MS.
