Abstract

The tea plant, Camellia sinensis L., is a well-known natural product with significant health advantages. The main catechin found in green tea leaves is epigallocatechin gallate (EGCG), which has potent antioxidant properties. EGCG is a common active ingredient in products from the medical and cosmetics industries. This study examines the antioxidant properties and total phenolic content (TPC) of an EGCG-rich fraction (ERF) that is extracted from green tea leaves. TPC was quantified using the Folin-Ciocalteu method, with absorbance measured via UV-VIS spectrophotometry at 760.5 nm. Antioxidant activity was assessed using the 1,1-diphenyl-2-picrylhydrazyl (DPPH) assay, with absorbance recorded at 516 nm. The findings indicated that the TPC of ERF was 437.18 mg GAE/g ± 5.54, while the IC50 value for antioxidant activity was 4.47 mg/L, This value was lower than that of the positive control, Vitamin C, which exhibited an IC₅₀ of 5.07 mg/L. These results suggest that ERF could be developed into a natural ingredient for cosmetics and dietary supplements.

Konsumsi buah dan sayur setiap hari memberikan banyak manfaat bagi tubuh kita, bukan saja rasanya yang enak tapi buah dan sayur kaya akan antioksidan yang bermanfaat untuk mencegah terjadinya stres oksidatif dan bisa menjadi salah satu upaya dalam mencegah dan mengobati hipertensi. Berbagai buah dan sayuran banyak yang telah diteliti memberikan khasiat antihipertensi. Pada pengabdian masyarakat ini kami mengadakan Pelatihan pembuatan nutrisi dan penyuluhan penyakit hipertensi pada anggota PKK RT. 014 Perumnas Klender Jakarta Timur.
