Abstract

Tanaman teh (Camellia sinensis) merupakan salah satu komoditi tanaman perkebunar unggulan di Indonesia. Senyawa yang terkandung dalam daun teh terdiri dari kafein, katekin, flavonol, klorofil, pektin, karbohidrat, dan enzim. Kafein merupakan substrat aktif yang memiliki khasiat sebagai stimulansia sistem saraf pusat dan otot jantung. Katekin adalah senyawa yang memiliki aktivitas antioksidan karena gugus fenol yang dimilikinya. Kandungan kafein dan katekin dalam teh dapat dianalisis dengan berbagai macam metode diantaranya Titrasi Bebas Air, Spektrofotometer UV-Vis, dan Kromatografi Cair Kinerja Tinggi (KCKT). Berdasarkan studi Pustaka yang dilakukan mengenai penetapan kadar kafein dan katekin dari beberapa jenis teh. Metoda analisis yang paling umum digunakan dan memiliki tingkat akurasi yang baik adalah KCKT dengan menggunakan fase diam C18 dan diukur pada suhu 25°C dengan 2. max 280 tum. --- The tea plant (Camellia sinensis) is one of the leading plantation crop commodities in Indonesia. The compounds contained in tea leaves consist of caffeine, catechins, flavonols, chlorophyll, pectin, carbohydrates, and enzymes Caffeine is an active substrate that has efficacy as a stimulant of the central nervous system and heart muscle. Catechins are compounds that have antioxidant activity due to their phenol group. The caffeine and catechin content in tea can be analyzed by a variety of methods including Water-Free Titration, UV-Vis Spectrophotometer, and High Performance Liquid Chromatography (HPLC). Based on literature studies conducted on the determination of caffeine and catechin levels of several types of tea. The most commonly used and accurately good method of analysis is HPLC using the stationary phase of Cla and measured at a temperature of 25°C with a & max of 280 nm.
