OBJECTIVE: To analyze and identify the chaenomeles sinensis koehne. METHODS: The characteristic cells in chaenomeles sinensis koehne were identified by microscopic identification. According to the Pharmacopoeia of the People’s Republic of China( 2015 edition), the moisture, total ash, acidity and extraction were determined. TLC method was adopted to identify the chaenomeles sinensis koehne. The static headspace sampling technique was used to collect the aroma components of chaenomeles sinensis koehne, and its composition was analyzed by gas chromatographymass spectrometry( GC-MS). RESULTS: The characteristics of the chaenomeles sinensis koehne powder were significant in microscopic identification. The spot identified by TLC was clear, and the test, control and control materials had corresponding spots in the same position. By GC-MS analysis combined with the NIST database search, the aroma components of chaenomeles sinensis koehne mainly included acids, alcohols, aldehydes, ketones, lipids and olefins, among which aldehydes, ketones, olefins were critical components that contributed to aroma components of chaenomeles sinensis koehne. CONCLUSIONS: Chaenomeles sinensis koehne is rich in aroma components and has higher nutritional value and medicinal value. [ABSTRACT FROM AUTHOR]
