Characterization of crude drugs and henna leaves extract (Lawsonia inermis Linn) and determination of total phenolic content and antioxidant activity test

Lawsonia inermis Linn is the plants into the Lythraceae family. This plant has proven to be able to treat a variety of diseases. This research were aimed to identify the characterization of ethanol extracts and simplicia of henna leaves, determine the total phenolic content with Folin-Ciocalteau method and antioxidant activity with Ferric Reducing Antioxidant Power (FRAP). The extraction was performed using 70 % ethanol. Characterization of simplicia was a powder, greenish brown color, bitter tasted and a distinctive odor. The loss of drying simplisia was 4.92 % ± 0.16, total ash was 4.61 % ± 0.02, acid insoluble ash was 4.43 % ± 0.14, water soluble concentration was 3.30 % ± 0.06, and ethanol soluble concentration was 25.46 % ± 0.18. Characterization of ethanol extracts was viscous, brown in color, typical odor and bitter tasted. The water content of ethanol extracts was 9.98 % ± 2.00, total ash content was 2.63 % ± 0.91, and non acid soluble ash content was 0.36 % ± 0.11. The results of the determination of the total phenolics of ethanol extracts was 16.02 g/100 g. And antioxidant activity of ethanol extract was 2.85 mmol Fe (II)/100
