Abstract

Pegagan (Centella asiatica (L) Urban) is a herbal plant which is based on preclinical testing showed has an
activity to increase intelligence through an antioxidant mechanism. The purpose of this research were to determine the

of Pegagan leaves. Pegagan leaf treatment consist of 2 factors, pretreatment (blanching, non blanching) and drying
(oven, sunlight). The results of the study simplicia pegagan leaf powder has a value of total phenolic content from
124.98 to 219.45 mg GAE / 100g, total flavonoids content from 131.67 to 196.74 mgEK / 100g, and the antioxidant
activity from 138.72 to 310.72 mgGAEAC / 100g. Blanching treatment at a temperature of 80°C for 60 seconds and
drying in an oven at 50°C for 3 hours provides the highest antioxidant capacity value 310.72 mgGAEAC / 100g, total
phenolic content 219.45 mg GAE / 100g, total flavonoid content 196.74 mgQE / 100g.
