摘要

Zingiber Officinale Roscoe, a famous plant that has been used worldwide for the consumption and treatment of human ailments. In Thailand, ginger is grown in many areas throughout the country. Lampang is subjected to be one of the northern provinces where ginger growing had remarkably increased in recent years. This study aimed to determine the amounts of 6-gingerol and camphene from Z. Officinale Roscoe grown in Ban Pha-Daeng, Ngao District, Lampang Province in 2020 and 2021. Dried rhizome of Z. Officinale was extracted with hexane, ethyl acetate and methanol. 6-gingerol and camphene of three crude extracts were analyzed using High Performance Liquid Chromatography -Photo Diode Array (HPLC-PDA) method. The content of 6-gingerol in all extracts was found in the range of 1.95 to 13.85 mg/g while the content of camphene was found in the range of 1.39 to 51.97 mg/g. The level of 6-gingerol and camphene in ethyl acetate extracts was greater than the hexane and methanol extracts. The result indicated the amounts of 6-gingerol and camphene of Z. Officinale grown in 2020 was higher compared to the content in 2021.
