ABSTRACT
Volatile components of Lonicerae Japonicae Flos in bud stage extended type Beihua 1 were determined by the headspace solid-phase micro-extraction, compared with traditional cultivar Damaohua. There are fifty-two volatile compounds were identified and the relative content of the volatiles was calculated by the area normalization method. Thirty-nine compounds were found in Beihua 1, whereas thirty-three components in Damaohua. Total twenty identical compounds existed in Beihua 1 and Damaohua. The contents of alcohols and hydrocarbons of Beihua 1 were higher significantly than that of Damaohua, while significantly lower than that of Damaohua in ketones content. Besides, twenty components were only detected in Beihua 1, such as methyl nicotinate, hexadecanoic acid, methyl ester,acetophenone, nonanoic acid.
