Abstract

The Pegagan plant has a scientific name in the form of Centella asiatica L. which is included in the Centella genus, Apiaceae family, and kingdom Plantae. Pegagan (Centella asiatica L.) has distinctive bioactive components, namely triterpene ester glycoside compounds in the form of asiaticoside and madecassoside, and triterpene group compounds in the form of Asiatic acid and madecassic acid. In this study, the extraction of bioactive components from pegagan was carried out using the Microwave-Assisted Extraction (MAE) method and will study the effect of ethanol solvent concentration in the extraction of bioactive compounds. Analysis of the extracted bioactive content was carried out by analyzing the total phenol content using the Folin-Ciocalteau reagent and ANOVA analysis. The results obtained from the study were in the form of total phenol content as an indication of the presence of bioactive compounds, namely at operating conditions of 450 watts of power, 50% ethanol concentration with a radiation time of 15 minutes which resulted in a total phenol content of 21.9244 mg AGE/g sample. In the ANOVA analysis with ethanol solvent, variables that gave a significant response to the total phenol content were microwave power, radiation time, and ethanol concentration with an R-square value of 95.31%. The effect of ethanol concentration on the total phenol content produced, namely the concentration of pure ethanol solvent will produce extracts with the smallest total phenol content, the effect of extraction time on total phenol content, namely the longer extraction time will increase the total phenol content. Maximum total phenol content using ethanol solvent that is, at operating conditions of 450 watts of power, 10% ethanol concentration with a radiation time of 15 minutes which resulted in a total phenol content of 520 mg AGE/g sample.

Abstract

Pegagan (Centella asiatica (L.)) is an herbaceous plant that grows and flowers throughout the year. Pegagan has been used for hundreds of years, especially in the dermatology and cosmetology industries. Pegagan (Centella asiatica (L.)) has distinctive bioactive components, namely triterpene ester glycoside compounds in the form of asiaticoside and madecoside, as well as triterpene group compounds in the form of asiatic acid and madecasic acid. There are various extraction methods to produce the following compounds, namely, conventional extraction methods and modern extraction methods. The two methods have differences in the results obtained. Therefore, the difference in the extraction method will determine the outcome of the difference in the levels of a compound. So that this research was carried out on the effect of Pegagan (Centella asiatica (L.)) extraction using a comparison of the Microwave-Assisted Extraction (MAE), and Ultrasound-Assisted Extraction (UAE) methods on the total phenol content in the Pegagan (Centella asiatica (L.)) extracted. The extracted bioactive content was analyzed by analyzing the total phenol content using the Folin-Ciocalteau reagent method and analyzing the data through the Analysis of Response Surface Design expert 11 to see the significance of the research variables. The results obtained from the study compare the optimal conditions for the total phenol content, namely, the comparison between the UAE and MAE methods for Centella asiatica (L.). Extracted with ethanol solvent, which is more optimal using the MAE method, because it can produce 1130,7882 mg quickly.
