Study on Extraction Technology of Quercitr in Urtica

Abstract

Abstract: The extraction technology of quercitr in urtica was studied with ethanol as extractor. The contained amount of quercitr was measured by HPLC.The best conditions were chosen through L9(34) orthogonal test. The results showed the first factor affecting extractor productivity was volume percentage of ethonal. The second and the third ones were rotio of feed liqued and temperature respectively. The best extraction conditions are to use 70% ethanols extractor with the ratio of feed liqued of 1:30 at the temperature of 80 ℃ for 3 h. The extraction productivity 211 mg/kg.

Key words: urtica, quercitrin, extraction, technology
