Standardization of 70% ethanol extract and 96% lime leaves as antioxidants with DPPH and FRAP

Abstract

The lime plant (Citrus aurantifolium S.) is a small tree, smells good. The fruit is slightly rounded with a slightly tapered tip. Lime has a characteristic taste that is soft, watery, and very sour with a sharp aroma. The use of lime and lime leaves is quite extensive, among others, as ingredients for traditional medicine, for beauty treatments, for flavoring food and for adding a fresh taste to drinks. The pharmacological effects of lime leaves include antioxidants properties. The ethanol extract of lime leaves (Citrus aurantifolium S.) was carried out by maceration using ethanol 70% and 96% which were characterized and standardized. The main target of this research is the production of standardized, characterized extracts that are safe, stable in their use.
