Abstract:

Kecombrang (Etlingera elatior) is one of the native plants of Indonesia. E.elatior is used as a condiment, food, medicine, and ornament. The antioxidant properties of rhizomes, leaves, and flowers of E.elatior has not been reported. This study aimed to explore the antioxidant capacity of the rhizome, leaves, and flowers of E.elatior in extracts and fractions. The rhizome, leaves, and flower of E.elatior were macerated by ethanol 96% to generate crude extract. The crude extract was fractionated by n-hexane, ethyl acetate, and ethanol 96% to generate n-hexane, ethyl acetate, and ethanol fraction

Abstract:

Ceylon olive (Elaeocarpus serratus L.) leaves have shown many pharmacological effects. Standardization of crude drug and extract needs to be conducted to assure the quality of the said material and further to support the pharmacological, pharmacokinetics, and toxicity effects. Standardization of Ceylon olive leaf extract is carried out to determine the standard parameters of crude drug and ethanolic extract of Ceylon olive leaves. Determination of the quality standard of crude drug and extract includes specific and non-specific parameters. The extract was obtained from a 70% ethanol maceration
