To establish a method for determination the content of functional components of various medicinal and edible homology (glycyrrhizic acid, kaempferol-3-O-rutinoside, isoflavan glucoside,luteolin-7-glucoside, puerarin, chlorogenic acid, salidroside and glycyrrhizin) in botanical beverages by ultra-high pressure liquid chromatography.
The appropriate amount of botanical beverage sample was weighed, the sample was vortex-dispersed with a methanol-water solution and then performed ultrasound-assisted extraction to fully release the target dispersed components. After centrifugation, the supernatant was collected. An EC-C18 chromatographic column was used for the separation of various components in the extract, and quantitative analysis was performed using the external standard method., the content of 8 kinds of efficacy components in the botanical beverage was simultaneously detected.
The 8 kinds of active components exhibited good linearity within the mass concentration range of 0.50–25.00 mg/L, with correlation coefficients (r)>0.998. The limits of detection and limits of quantitation for the 8 kinds of functional components ranged from 0.05 to 0.50 mg/kg and 0.16 to 1.50 mg/kg,respectively. The recovery rates were between 83.2% and 96.1% and the relative standard deviations of the test results were 3.2%–6.2% (n=3).
The established method demonstrates excellent precision and recovery rates,along with satisfactory sensitivity, making it suitable for determining the content of these 8 kinds of pharmacologically active components in botanical beverages.
