Physicochemical evaluation and essential oil composition analysis of Hyssopus cuspidatus Boriss from Xinjiang, China.
BACKGROUND
It is reported that the plant Hyssopus cuspidatus Boriss from Xinjiang has great value. This article deals with the detailed pharmacognostic evaluation of the crude drug H. cuspidatus Boriss.


METHODS
The essential oil of H. cuspidatus Boriss from Xinjiang, China, was extracted by the method of hydrodistillation and the chemical composition of the essential oil was analyzed by gas chromatography-mass spectrometry (GC-MS).


RESULTS
The yield of essential oil based on the dry weight of the plant was 0.6%(w/w). Fifty compounds accounting for 99.42% of the total oil were identified. The major components were oxygenated terpenes (66.33%), monoterpenes (26.14%), oxygenated sesquiterpenes (1.25%), and octane (1.85%).


CONCLUSIONS
Oxygenated terpenes were the main group of the compounds. The physicochemical parameters presented in this article may be proposed as parameters to establish the authenticity of H. cuspidatus Boriss and can possibly aid pharmacognostic and taxonomic species identification.
