Abstract

Hemp (Cannabis sativa L.) is a multi-purpose plant that recently get lots of attention in Thailand. In previous years, there are various studies have been done regarding to the application of hemp fiber, especially in textile sector. After the government has unlocked regulation regarding to hemp cultivation and its application, hemp seed has become remarkable part as oil content in the seeds can be used for multiple purposes. Extraction process of hemp oil become more important in order to get higher yield. So, this research interest has been focused to compare the extraction methods of conventional and soxhlet extraction using water, n-hexane and petroleum ether as extraction solvent. The experimental results showed that conventional extraction method for hemp seed oil using n-hexane has highest yield of 18.78%, followed by petroleum ether of 17.06%, and water of 4.56%. In addition, soxhlet extraction method using petroleum ether showed significantly (p≤0.05) highest yield of 24.44% compared to those of n-hexane 21.65% and of water 1.27%. According to the experimental results, it was concluded that soxhlet extraction method using petroleum ether as extraction solvent is recommended in order to get higher oil yield from hemp seed.
