Abstract

Centella asiatica is a wild plant that contains bioactive components that are beneficial for the body. However, optimal exploration for the production of Centella asiatica essential oil still needs to be studied further in producing Centella asiatica essential oil with the best quality, as well as the extraction method and type of solvent used. This research examines the extraction results of Centella asiatica essential oil using the Microwave-Assisted Hydrodistillation method with several solvents such as water, ethanol, and n-hexane and the pretreatment temperature in the Centella asiatica drying process. Several parameters analyzed and evaluated the quality of Centella asiatica essential oil in this study including yield, density, chemical compound content, acid number, and ester number. Meanwhile, the analysis method used was ANOVA with a 2-factor randomized block design.
