- Abstract
- To determine the optimum extraction conditions that give the highest yield of isoquercitrin and caffeic acid from Aster scaber, the effects of four extraction variables (solvent concentrations, extraction time, number of repeated extraction, and solvent volumes) on isoquercitrin and caffeic acid yield was examined via HPLC-UV. Our results showed that the highest extract and isoquercitrin yield were observed when A. scaber was extracted with 450 mL distilled water for 8 hr repeatedly for three times. In case of caffeic acid, the content was higher in the two repeated extracts. Also, content analysis of isoquercitrin in Aster species was performed in which A. fastigiatus, A. ageratoides, and A. scaber exhibited the highest isoquercitrin content at 6.39, 5.68, and 2.79 mg/g extract, respectively. In case of caffeic acid, the highest content of A. scaber and A. glehni was 0.64 and 0.56 mg/g extract, respectively. This study reports an optimized method for extraction of isoquercitrin and caffeic acid from A. scaber and evaluates potential sources of the compounds. © 2018, Korean Society of Pharmacognosy.
