Abstract

In this study, Chrysanthemum indicum L. (C. indicum) was steamed for different time duration (60, 90, and 120 seconds). After that, C. indicum was dried with 3 different methods (sun drying, drying at 45^oC, cool-drying) and then were investigated the quality in the packaging condition at low pressures (100mmHg, 200mmHg, 300mmHg). The results showed that steaming at normal pressure for 90 seconds, drying in cooling dryers at a temperature of 30^oC, and storing in vacuum PP packaging at a pressure of 100mmHg are the best quality pre-processing and preserving methods. C. indicum can be stored for more than 9 months, the average content of luteolin-7-0-β-D-glucoside average is 0:10%, better than the required level in the Hong Kong Pharmacopoeia of 0:035%.
