The study of extraction yield enhancement of the essential oil from fresh Michelia alba. DC

The scientific name for Champaka is Michelia alba DC. It is a medium-sized perennial, known for its rapid growth and year-round blooming. Among the most economically valuable plants, Champaka flowers emit a unique fragrance that captivates the perfumery industry, making them highly sought after by farmers.

The distinct aroma of Champaka flowers has a soothing effect on the nervous system, providing a refreshing sensation and aiding in restful sleep. This versatile herb is utilized to treat various ailments such as headaches, sinusitis, cough, inflammation, flatulence, and nausea. Additionally, Champaka flower extracts are used as essential components in various products, ranging from food flavorings to cosmetics, effectively extending the shelf life and enhancing their value.

Although most Champaka flower essential oils are extracted through steam distillation, this method requires a considerable amount of time and involves the use of heat and solvents, leading to a decline in the oil's quality and missing the true scent of fresh flowers. Reports from the Bureau of Agricultural Product Promotion and Management and analyses from Thailand's Herbal Research Institute indicate that outdated and inefficient extraction technologies contribute to the country's sluggish herbal extract export growth compared to neighboring nations.

To address these challenges, the research project " The study of extraction yield enhancement of the essential oil from fresh Michelia alba. DC" aims to develop a Thai medicinal plant extraction process using low-critical fluid technology at lower temperatures. The incorporation of mathematical models will help predict extraction results from various variables, streamlining the selection process for optimum conditions. These equations can be adapted to predict extraction outcomes for other flowers, allowing for the adjustment of relevant variables to achieve maximum essential oil production. The findings will be published in international academic journals to foster knowledge exchange and enable others interested in essential oil extraction from fresh flowers to elevate the value of Thai agricultural products. This initiative will also address the issue of falling agricultural prices during periods of oversupply in the future.

Moreover, the essential oil extracts from fresh Champaka flowers can serve as a foundation for the development of other high-value products, contributing further to the agricultural sector's growth and prosperity.
