【Abstract】 Object To identify the differences of chemical constituents of Dragon’s Blood obtained by different extract processing. Methods The mentioned Dragon’s Blood was analyzed by TLC, UV spectro photometry, and HPLC. Results The contents of dihydrochalcone in Dragon’s Blood by the new extract processing were higher than that by traditional one’s, while the contents of flavonoid and stibene were lower. Conclusion The heating free technology is a new technique that is an original with higher extract rate, and it is worth of spreading. It will promote the modernization of TCM.更多还原
