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

Funtumia elastica (Lagos silk rubber), a member of the Apocynaceae family, is popularly used in the Western region of Nigeria in the treatment of hemorrhoid and more recently malaria fever. In this study, we evaluated the proximate composition, mineral content and phytochemical screening of extracts of F.elastica (FE) leaves. Dried powdered plant leaves were extracted in ethanol to obtain the ethanolic extract and distilled water to obtain aqueous extract. The resulting extracts were used to analyze for the proximate content, mineral content and phytochemicals constituents. The proximate analy

Abstract:
Andrographolide (AGP), a major component of Andrographis paniculata (Burm.f.) Nees (AP), has several biological activities. Nevertheless, poorly water solubility and low bioavailability of AGP lead to decrease clinical benefits. Therefore, this study aims to develop of AP extract-chitosan solid dispersion using central composite design (CCD) to enhance AGP release. AP crude extract was obtained by Soxhlet extractor using 85%v/v ethanol as a solvent extraction. Then, AP extract, chitosan, and poloxamer 188 in the concentrations provided by CCD was spray dried.

Abstract:
Moringa oleifera, commonly known as horse radish tree or drumstick tree is a perennial multipurpose tropical tree. It can be used as medicine, cosmetic and functional food, among others. The benefits of using the leaves are ascribed to the presence of a number of antioxidants. Nowadays it is widely cultivated and naturalized in many countries. Simple methods to extract antioxidants from Moringa leaf are lacking, which were established, stability of antioxidants was assessed, and residue left after extraction was explored for use as animal feed, with the aim to scale-up the process to industria
