主 题：Extraction Purification Adsorption isotherm Hybrid organic-inorganic monolith Quercetin Myricetin
摘 要：A new hybrid organic-inorganic monolithic cartridge was synthesized and used as the selective sorbent for the extraction and purification of quercetin and myricetin from Chamaecyparis obtusa via a solid-phase extraction *** morphology of the monolithic material was examined by field emission-scanning electron microscopy and a Brunauer-Emmett-Teller（BET） *** adsorption capacity of the obtained material for quercetin and myricetin was investigated by fitting the adsorption data to four different adsorption equations,of which the LangmuirFreundlich isotherm was selected as the most suitable *** optimized conditions,good calibration curves were observed at nine concentrations ranged from 0.5 μg/mL to 100.0 μg/mL of quercetin and *** extraction recovery ranged from 74.5％ to 84.6％ and the inter-and intra-day relative standard deviations were 6％.This type of hybrid monolith has potential for the separation and purification of bioactive compounds from natural plant extracts.
