Abstract
Antioksidan adalah molekul yang dapat menghambat oksidasi
molekul lain. Antioksidan dapat melindungi kulit dari berbagai
kerusakan sel akibat sinar UV, anti aging. Daun teh mengandung 30
40% polifenol yang sebagian besar dikenal sebagai katekin. Katekin
(polifenol) adalah antioksidan yang kuat. Tujuan dari penelitian ini
untuk mengetahui formulasi lotion ekstrak daun teh hijau (Camellia
sinersis) yang menghasilkan uji mutu fisik (uji organoleptik, uji pH, uji
homogenitas, uji viskositas, uji daya sebar) dan stabilitas yang baik dan
dapat menghasilkan aktivitas antioksidan terbesar berdasarkan metode
DPPH.
Daun teh hijau diekstraksi menggunakan pelarut etanol 70%
dengan menggunakan metode maserasi. Pembuatan sediaan lotion
diformulasi dengan konsentrasi basis 1,5%, 3%, dan 6%. Lotion
ekstrak daun teh dilakukan pengujian mutu fisik dan stabilitas
dilanjutkan pengujian aktivitas antioksidan dengan metode DPPH.
Antioxidants are molecules that can impede other molecules'
oxidation. Antioxidants protect the skin from various uv, anti-aging,
cell damage. Tea leaves contain 30 to 40% of polyphenols, most of
which are known as catchers. The mannequins (polyphenols) are
powerful antioxidants. The purpose of this study is to know the
formulation of green tea leaf extract lotion (camellia synersis) that
results in physical quality tests (organoleptic tests, ph tests,
homophobic tests, viscosity tests, spread tests) and may produce the
greatest antioxidal activity based on DPPH methods.
Green tea leaves are extracted using a 70% ethanol solvent
using the maseration method. Availability of lotions is formulated with
a 1,5%, 3%, and 6% concentration base. Tea leaves extract lotions are
made by physical quality and stability, followed by the anti-oxidant
activity, DPPH method.
