A new sapogenin named Julibrogenin A was isolated from the stem bark of Albizzia julibrissin Durazz (Albizziae Cortex). Based on chemical and spectral studies, their structure has been identified as 21-O-(2-hydroxymethyl-6-methyl-6-methoxyl-2,7-octadienoyl)-acacic acid. In addition, machaerinic acid lactone, machaerinic acid methylester, acacigenin B and(More)
Epidemiologic evidence has shown inconsistent findings regarding the relationships between abdominal fatness, as measured by waist circumferences (WC) or waist-to-hip ratio (WHR), and risks of pre- and postmenopausal breast cancer (BC). A dose-response meta-analysis of prospective studies was conducted to address these issues. Potentially eligible studies(More)
An enzymatic semi-solid surface fluorometric method is described for the determination of serum creatinine on silicone-rubber pads. In this method, the glutamate dehydrogenase, alpha-ketoglutarate, ADP and NADH are mixed, then 30 microliters of diluted serum is added. After the free ammonium ion in serum is consumed, creatininase is added to initiate the(More)
Three new saponins named Julibroside J1, J2 and J3 were isolated from the stem bark of Albizzia julibrissin Durazz (Albizziae Cortex). Based on chemical and spectral methods, e.g. 1H- and 13C-NMR, DEPT, COSY CH-COSY, TOCSY, HMQC-COSY, HMQC-TOCSY, NOESY, HMBC, their structures have been identified as; Julibroside J1 (one triterpene, nine sugars, two(More)
