Quality Assessment of Artificial Aquilaria sinensis by"Cutting Inducing Technique" / 中国药房

ABSTRACT

OBJECTIVE:To conduct the quality assessment of artificial Aquilaria sinensis by"cutting inducing technique", and provide reference for its scientific planting and harvest. METHODS:GC-MC and HPLC were adopted to detect the volatile in-gredients,characteristic spectrum,incense tetraol and alcohol-soluble extract contents in 3 batches of artificial A. sinensis(Num. 1, 2,3,respectively for 5,10,20 years)by"cutting inducing technique". RESULTS:The volatile ingredients of 3 batches of artifi-cial A. sinensis mainly consisted of aromatic compounds,sesquiterpene compounds,fatty acid compounds and chromone com-pounds. The characteristic spectrums of samples 2,3 were basically the same with the reference substance of A. sinensis. The in-cense tetraol contents of 3 batches of samples were 0.078%-0.254%,and alcohol-soluble extract contents were 12.4%-20.8%. The characteristic spectrum and the incense tetraol content of sample 1 were not conformed to the standards in Chinese Pharmacopoeia (2015 edition,part 1). CONCLUSIONS:Artificial A. sinensis by"cutting inducing technique"shows similar volatile ingredients to natural A. sinensis. The quality of artificial A. sinensis for more than 10 years is conformed to the standards in Chinese Pharmaco-poeia(2015 edition,part 1),which can be used as medicine,replacing the natural A. sinensis.
