Abstract
AbstractThe longan fruit, widely grown and consumed in Southeast Asia, contains an abundance of essential natural chemicals present in its flesh and seeds. The microwave‐assisted approach is used to extract these components, which include total phenolic compound and corilagin. The optimization of the extraction process included factors such as the sample ratio (0.5–1.5 g/30 mL), time (10–20 min), and microwave power (600–700 W). These variables were examined using the response surface approach. The statistical analysis revealed that the data was most accurately represented by a quadratic polynomial equation. The decision coefficients for total phenolic compounds and corilagin were found to be 0.9956 and 0.9485, respectively, indicating a high level of accuracy. The result was that the optimal conditions to obtain the highest total phenolic compound and corilagin from longan extract are 22.214 mgGAE/gDW and 55.137 mg/gDW, respectively. The sample was extracted under a ratio of 0.97 g/30 mL set at microwave power at 695.74 W, with an extraction time of 15 min. This study suggests that microwave‐assisted, water‐based extraction can produce healthful, eco‐friendly concentrated longan extracts, yielding high levels of corilagin and phenolic compounds.
