Abstract
The objectives of this research were to compare the yield and total phenolic content of extracts from Velvet tamarind of peels and seeds by using different extraction methods. The velvet tamarind peels and seeds were analyzed for yield and extracted using three different methods as 1) maceration extraction, 2) shaking extraction, and 3) microwave-assisted extraction. The results showed that the peels and seeds of velvet tamarind yielded 92.07±3.65% and 95.38±1.65%, respectively. When examining the extracts from peels and seeds using the three extraction methods, the result was found that method 3, microwave-assisted extraction, provided the highest yield for both peels and seeds of velvet tamarind. The yield from the peels was 20.07±3.65%, and seeds was 16.56±1.65%. Additionally, method 3 also yielded the highest total phenolic content in both the peels and seeds, with the peels containing 142.40±2.32 mg GAE/g dry weight and the seeds containing 159.72±5.32 mg GAE/g dry weight. These findings demonstrate the efficiency of microwave-assisted extraction in extracting total phenolic compounds from velvet tamarind of peels and seeds, which can be utilized as active ingredients in cosmetic products and other products with high antioxidant properties.
