Li CY, Lee EJ, Wu TS (2004) Antityrosinase principles and constituents of the petals of Crocus sativus. Journal of natural products 67, 437-440 [PubMed:15043425] [show Abstract] Three new monoterpenoids, crocusatin-J (1), -K (2), and -L (3), and a new naturally occurring acid, (3S),4-dihydroxybutyric acid (4), together with 31 known compounds were isolated and identified from the methanol extract of the petals of saffron (Crocus sativus). Their structures were established by spectroscopic methods. Among them, crocusatin-K (2), crocusatin-L (3), and 4-hydroxy-3,5,5-trimethylcyclohex-2-enone (8) showed significant antityrosinase activity, and protocatechuic acid (18), kaempferol (24), and kaempferol 7-O-beta-d-glucopyranoside (27) were more effective in scavenging alpha,alpha-diphenyl-beta-picrylhydrazyl (DPPH) radicals than alpha-tocopherol. In addition, the mechanism of tyrosinase inhibition by crocusatin-K (2) is also discussed. | Manguro LO, Ugi I, Hermann R, Lemmen P (2003) Flavonol and drimane-type sesquiterpene glycosides of Warburgia stuhlmannii leaves. Phytochemistry 63, 497-502 [PubMed:12770606] [show Abstract] An investigation of methanolic extract of Warburgia stuhlmannii leaves has led to the isolation of two new drimane-type sesquiterpene glycosides characterized as mukaadial 6-O-beta-D-glucopyranoside, mukaadial 6-O-alpha-L-rhamnopyranoside together with two other novel flavonol glycosides identified as 3',5'-O-dimethylmyricetin 3-O-beta-D-2",3"-diacetylglucopyranoside and 3'-O-methylquercetin 3-O-beta-D-2",3",4"-triacetylglucopyranoside. The known compounds; mukaadial, deacetylugandensolide, quercetin, kaempferol, kaempferol 3-O-alpha-L-rhamnopyranoside, quercetin 3-O-beta-D-glucopyranoside, kaempferol 7-O-beta-D-glucopyranoside, myricetin 3-O-alpha-L-rhamnopyranoside, quercetin 3-O-alpha-L-rhamnopyranoside, quercetin 3-O-sophoroside and isorhamnetin 3-O-beta-D-glucopyranoside were also isolated from the same extract. | Ahmed KM, Marzouk MS, el-Khrisy EA, Wahab SA, el-Din SS (2000) A new flavone diglycoside from Carthamus tinctorius seeds. Die Pharmazie 55, 621-622 [PubMed:10989844] [show Abstract] From the aqueous ethanol extract (AE) of Carthamus tinctorius seeds, a new acacetin diglycoside has been isolated and identified as acacetin 7-O-beta-D-apiofuranosyl-(1"'-->6" instead of 6')-O-beta-D-glucopyranoside together with previously isolated kaempferol 7-O-beta-D-glucopyranoside, acacetin 7-O-alpha-L-rhamnopyranoside and acacetin. The structures of these metabolites have been established on the basis of chemical, chromatographic and spectral methods. |
