Abstract

Bunga tasbih mengandung antosianin yang merupakan suatu senyawa yang termasuk golongan flavonoid. Antosianin dapat dimanfaatkan sebagai antioksidan. Antioksidan merupakan senyawa yang menghambat, mencegah dan menghilangkan kerusakan oksidatif pada molekul target. Untuk mendapatkan senyawa antosianin, dilakukan proses ekstraksi yang memiliki berbagai macam metode. Metode ekstraksi yang beranekaragam tersebut memiliki kelebihan dan kekurangan masing-masing. Penelitian ini bertujuan untuk membandingkan metode sokletasi dengan maserasi terhadap daya antioksidan ekstrak etanol bunga tasbih. Metode pengujian daya antiosidan ekstrak etanol bunga tasbih yang digunakan adalah metode DPPH. Hasil penelitian yang didapat adalah IC50 ekstrak etanol bunga tasbih yang diektraksi dengan metode sokletasi adalah 26,5 µg/mL dan termasuk memiliki daya antioksidan yang sangat kuat. IC50 ekstrak etanol bunga tasbih yang diekstraksi dengan metode maserasi adalah 32,7 µg/mL dan termasuk memiliki daya antioksidan yang kuat. Sebagai pembanding digunakan Vitamin C yang memiliki IC50 adalah 5,3 µg/mL dan termasuk memiliki daya antioksidan yang sangat kuat. Dari data tersebut, disimpulkan bahwa daya antioksidan ekstrak etanol bunga tasbih yang diekstraksi dengan metode sokletasi lebih kuat dibandingkan daya antioksidan ekstrak etanol bunga tasbih yang diekstraksi dengan metode maserasi.

Allicin in garlic will reduce inflammatory reactions and antibacterial, which will accelerate in healing wound. Garlics extract made in gel preparations with a concentration of 15% and 20%, then given to burns and cuts mice that have been divided into several groups. In testing, mice that had been made burns were divided into 4 groups and each group contain of 3 mice, namely the 15%, 20% concentration gel group. The Bioplacenton group as a comparison and also the control group. In the examination of cuts, the division of the group of mice that have been made the cuts is the same as the burn test, the comparison is Povidone iodine. From the burn test, the results are the 20% concentration gel group experienced the best healing after 18 days of gel administration and its healing power was better than Bioplacenton. The results of cuts testing is the 15% concentration gel group experienced the best healing and slightly better than Povidone Iodine.
