Abstract

Tea is one of the most commonly consumed beverages around the world. The chemical compounds contained in tea have a good effect on health because they contain polyphenolic compounds, catechins. This study examined the catechin compound content of black tea and green tea from Karanganyar (A) and Malang (B). This research aims to determine the differences in catechin levels in black and green tea types in Malang, East Java, and Karanganyar, Central Java plantations. The research method used was experimental. Identification of catechin content was done using UV-Vis Spectrophotometry method. Tea is extracted by brewing, 4 grams of green tea is brewed using distilled water for 6 minutes, while 5.6 grams of black tea is brewed using distilled water for 10 minutes with the comparison used is pure catechin solution. The results obtained for green tea Karanganyar (A) had a catechin content of 3.61±0.083%, green tea Malang (B) had a level of 2.97±0.037%, black tea Karanganyar (A) had a level of 3.14±0.065%, and black tea Malang (B) had a level of 1.60±0.009%. It is concluded that the catechin content of green tea is higher than black tea, and of the two samples, the high catechin content comes from Karanganyar (A). Keywords:          catechins, green tea, black tea, malang, karanganyar

Abstract

Abstract: Green tea is a plant that contains phytochemicals, namely polyphenols, alkaloids, volatile oils, polysaccharides, amino acids, lipids, and vitamin C. Flavonoids have antioxidant, anti-inflammatory, anti-allergic, and antibacterial activity. These advantages can be increased in terms of benefits and economic value by making it in the form of liquid soap. The addition of green tea is expected to increase the antioxidant effect of the soap preparations made. The study aims to provide training on making liquid hand-washing soap from steeping green tea leaves. The training activity for making liquid hand-washing soap with the addition of green tea was carried out as an effort to increase health independence and provide entrepreneurial provisions for the PKK community in Kranggan Village, Polanharjo, Klaten. The training was attended by 20 participants with presentation methods and practice in making liquid hand-washing soap. The result of this service activity is that the community knows how to make hand-washing soap from green tea and knows the function of the ingredients used in the process of making hand-washing soap.   Keywords: training, devotion, liquid soap, green tea
