[Qualitative and quantitative methods for Alpiniae Katsumadai semen].[Pubmed:21046736]
Zhongguo Zhong Yao Za Zhi. 2010 Aug;35(16):2091-4.
The qualitative and quantitative methods for the quality evaluation of Alpiniae Katsumadai Semen were established. Alpinetin, pinocembrin, cardamonin and Alnustone in the sample were identified by TLC. The contents of them were determined by HPLC. The separation was performed on a Ultimate XB-C18 column (4.6 mm x 250 mm, 5 microm) at 30 degrees C using a gradient elution consisting of mobile phase A (water) and mobile phase B (MeOH). The detection wavelength was 300 nm. The TLC method was suitable for the identification of alpinetin, pinocembrin, cardamonin and Alnustone. The linear ranges of the four reference compounds were 25.5-509 (r = 0.9999), 24.9-498 (r = 0.9999), 26.1-521 (r = 0.9999), 50.2-1003 ng (r = 0.9999), respectively. The average recoveries (n=9) of the four components were 97.95%, 97.36%, 97.50%, 98.02%, RSD < 1.9%. Nine samples were analyzed by the established methods. The results indicate that, the methods are simple, accurate, sensitive and reliable for quality evaluation of Alpiniae Katsumadai Semen.
Three non-phenolic diarylheptanoids with anti-inflammatory activity from Curcuma xanthorrhiza.[Pubmed:8255938]
Planta Med. 1993 Oct;59(5):451-4.
Bioassay-guided fractionation of a hexane extract of the rhizomes of Curcuma xanthorrhiza Roxb. (Zingiberaceae) led to the isolation of three non-phenolic diarylheptanoids, identified mainly by high-field 1H-NMR as trans-trans-1,7-diphenyl-1,3-heptadien-4-one (Alnustone), trans-1,7-diphenyl-1-hepten-5-ol, and trans,trans-1,7-diphenyl-1,3-heptadien-5-ol. The latter is reported for the first time as a plant constituent. Germacrone, curzerenone, and cinnamaldehyde were also isolated and identified. The three diarylheptanoids all exerted significant anti-inflammatory activity in the assay of carrageenin-induced hind paw edema in rats.
