| Abstract: | Objective To optimize the technology of extracting chemical constituents from niubangzi (the fruits of Arctium lappa). Methods With arctiin as a criterion, the water extraction and ethanol extraction technologies of extracting the constituents from niubangzi were compared by HPLC; and the L 9(3 4) orthogonal experimental design was used to optimize the conditions of the ethanol extraction technology. Results The conditions of the ethanol extraction technology of extracting the constituents from niubangzi were 70% ethanol, 1 hour of reflux, 8 fold solvent and 3 times of extraction. Conclusion With the extraction rate of arctiin as 94 98%, the optimized technology is stable and practical and worthy of a trial in pharmaceutical production. |
