[Research of chitins to technology of clarification for xiangjuganmaokeli extraction].

Objective: To study the procedure of chitosan to technology of clarification for xiangjuganmaokeli extraction and measure its content.

Methods: The best technology was choosed by orthogonal test. Relative density, the total solid, total sugar and the content of acacetin were examined after the nature clearness and chitins clarify. The total sugar was Counte-racted with ether siank, hydrolyzed with the phenol and sulfuric acid and examined in the 490 nm. Acaciin in powdered herb was determined by HPLC method.

Results: The chitin clarifies in front and back relative density, the total solid, the total sugar slightly descends, but the acacetin did not show the significant difference.

Conclusion: Chitins to technology of clarification for xiangjuganmaokeli extraction can attain the clearness result, and the acacetin did not show the significant difference in front and back.
