ABSTRACT
As a characteristic medical and edible products, Zanthoxylum armatum has come into being popular in the past 20 years, but it has not been recorded in the relevant standards of Z. bungeanum commodities, and there is no clear regulation for the definition of Z. armatum. This paper makes a textual research on the sources of Z. bungeanum commodities, and analyzes the differences and connections between Z. armatum and other Z. bungeanum commodities, and puts forward the new definition of Z. armatum. The definition of Z. armatum will help to stabilize the quality of Z. armatum, provide reference for the quality standard and quality evaluation of Z. armatum, and provide a reference for solving the mixed situation of Z. schinifolium in Z. bungeanum commodities.
ABSTRACT
Objective To develop an HPLC method for the simultaneous determination of the contents of dictamnolactone and skimmianine in the root of Zanthoxylum armatum DC. from Gansu Province. Methods The column was kromasil-C18 (250 mm×4.6 mm, 5 μm);the mobile phase was acetonitrile-water (65∶35);UV detection was performed at 254 nm;the flow rate was 1.0 mL/min;detected drift tube temperature was set at 30 ℃. Results The calibration curves were linear in the range of 0.205-2.05μg for dictamnolactone (r=0.999 9) and 0.199 6-1.996μg for skimmianine (r=0.999 7). The average recovery was 99.69%(RSD=0.57%) for dictamnolactone and 99.49% (RSD=1.04%) for skimmianine. Conclusion The method is simple and accurate. It is suitable for content determination of dictamnolactone and skimmianine in the root of Zanthoxylum armatum DC..
