[Study on extracting process for Tiao ZhiAn mixture].

OBJECTIVE

To study the technology of optimal extraction for Tiao ZhiAn mixture.

METHODS

Optimization of the influence of the mixed volatile oil extracting of Ligusticum chuanxiong Hort., Angelica sinensis (Oliv.) Diels and Curcuma longa L. was chosen by single-index test. Orthogonal test was employed for selecting the optimum of extraction technology by colligation score as the indexes of the contents of stilbene glucoside of Polygunum multiflorum Thunb, total solid matters in water extraction.

RESULTS

The best technology for extracting Ligusticum chuanxiong Hort., Angelica sinensis (oliv.) Diels and Curcuma longa L. was to add water nine times within eight hours. The way of adding water six times to the medicine sediment and other herbs, extracting 3 times in one hour each time was considered the optimum extraction technology.

CONCLUSION

The considerable extraction rate of active components in the drugs is achieved by applying the selected technology, and the simple method is fit for manufacturing Tiao ZhiAn mixture.
