栀子属的果实有好几种。分离并鉴定了类胡萝卜素。采用紫外/可见、共层析和LC-MS对Crocetin(1)进行了表征。通过UV/vis， H-1-NMR和C-13- NMR鉴定了藏红花素（藏红花素二（β -龙胆生物基）酯）(6)，通过UV/vis， H-1-NMR和LC-MS鉴定了藏红花素单（β -龙胆生物基）酯(4)。有很强的迹象表明存在13z -藏红花素(9)（UV/vis， H-1-NMR和LC-MS）。从藏红花（Crocus sativus L.）中分离到另一种藏红花素(1)糖基酯。通过UV/vis、h -1 nmr和MS鉴定其为西红花素（β -gentiobiosyl） （β -neapolitanosyl）酯(7)。
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.
