查询词典 hormones

Based on phylogenetic analysis, this paper reviewed the relationship between hormones including sex hormones and AVT, and vocal production and perception through all anuran species studied to date. We found that in anuran brains the AVT system related to vocal behaviors were very conservative while the sex hormone systems involved in vocal communication might be originated independently from varied taxa of anuran.

Samples were saponified with 20 g/L sodium hydroxide. The sexual hormones were then extracted with dichloromethane-acetic acetate (40∶1, v/v) under acidic conditions (pH 3, adjusted with 1 mol/L HCl ). An XTerraTMRP18 column was employed and a mixture of water-methanol-acetonitrile (50∶32∶18, v/v) was used as mobile phase. The seven sexual hormones were detected at 230 nm. The average spiked recoveries for the seven sexual hormones ranged from 75.6% to 97.8% with relative standard deviations of 1.9% to 7.2%. The linear ranges of determination were from 5 to 50 mg/L with correlation coefficients of 0.9999, and the limits of detection were from 3.7 to 12 ng.
