| Popis: | 105 Danshen (Salvia miltiorrhiza Bunge), whose roots were often used as medicine, belongs to the family Labiatae and Salvia genus. The main active components are two categories that the lipophilic diterpenoids and the hydrophilic phenolic acids. Post-harvest drying is the important procedure in order to preserve Chinese herbal medicine. But the active ingredients of danshen is unstable, susceptible to temperature and external environmental changes. So the experiment is discussing the differences by HPLC (High performance liquid chromatography) component analysis method to explore the idifferent drying methods such as freeze-drying, hot air drying, shade drying and sun drying for the roots of danshen in the active ingredients of the impact. The results show the highest content of phenolic acids is in freeze-drying that danshensu is 744.89±51.89 μg/g, salvianolic acid B is 13,534.37±417.42 μg/g and salvianolic acid A is 387.39 ± 16.95 μg/g, The highest content of tanshinone is in sunburn that dihydrotanshinone is 120.50±4.72 μg/g, cryptotanshinone is 657.86±34.77 μg/g, tanshinone I 240.24±22.04 μg/g and tanshinone IIA is 600.66±40.31 μg/g, second is by freeze-drying. The drying test was carried out at 40℃, 50℃, 60℃ and 70℃, respectively. The results showed that the highest content of phenolic acids is at 50℃ that danshensu is 503.70±25.41 μg/g, salvianolic acid B is 17,110.78±466.40 μg/g and salvianolic acid A is 166.58±11.00 μg/g, The tanshinones were best at 50℃, dihydrotanshinone is 97.08±2.72 μg/g and 70℃ dried cryptotanshinone is 461.65±27.73 μg/g, tanshinone I is 294.42±14.74 μg/g and tanshinone IIA 768.78±154.55 μg/g. 50℃ drying and 70℃ have the best contents. The results showed that the content of active ingredients in S. miltiorrhiza was higher by freeze drying, and 50℃ was the best when dried by hot air drying. |
