Abstract

Lime (Citrus aurantifolia) peel essential oils are complex metabolites mainly used as natural preservatives. The principal constituents include d-limonene, β-pinene, and terpineol. Moreover, essential oils (EOs) are potentially known volatile and unstable compounds, hence, they require proper packaging techniques, e.g., microencapsulation. The purpose of this study is to evaluate the binary methods of lime peel essential oils microencapsulation using complex coacervation. This involves the application of gelatin and sodium alginate coatings under two specific conditions, termed core/coating ratio 1:1.2, with modified stirring and core/coating ratio 1:2.0, with stirring speed of 600 rpm, respectively. The results showed the EOs preparation generated 0.70% yield characterized by good quality, fresh aroma, and pale-yellow coloration. Also, microcapsules delivered 37.06% yield, 39.18% oil content, 31.53% encapsulation efficiency (EE), and less smooth-edged SEM surface under condition I. Meanwhile, condition II demonstrated 51.46% yield, 58.66% oil content, 92.04% encapsulation efficiency (EE), and flat-curved, SEM surface. Furthermore, it was carefully observed condition II produced more superior microcapsules

Abstract

Phenolic compounds such as kaempferol (1), quercetin (2), and methyl caffeate (3) have been isolated from the ethyl acetate extract of Kalanchoe prolifera (Crassulaceae). The chemical structure of isolated compounds 1-3 were elucidated on the basis of spectroscopic evidence (UV, IR, NMR) and comparison with those compound previouly reported.DOI: http://dx.doi.org/10.15408/jkv.v0i0.5037

Abstract

Akway (Drimys beccariana Gibs) is an endemic plant of Papua. Ethnobotany is used as a medicinal plant, one of which is used as a malaria drug. This study aims to isolate, determine the chemical structure and evaluate the antimalarial activity of D. beccariana stem bark. Powder of D. beccariana bark is macerated with methanol and fractionated using n-hexane and ethyl acetate. Ethyl acetate extract was fractionated using gradient liquid chromatography (KCV) (n-hexane: ethyl acetate: methanol). The KCV fraction was separated by repeated gravity column chromatography and preparative thin layer chromatography (TLC-P) to obtain Isolate 1. Isolate 1 was determined by spectroscopic methods including UV-Vis, IR, 1D NMR, and 2D. Isolate 1 is determined by its compound structure which is 5,3'-dihydroxy-7,4'-dimethoxyflavone. 5,3'-dihydroxy-7,4'-dimethoxyflavone compounds evaluated antimalarial activity against Plasmodium falciparum in vitro with antimalarial activity better than artemisinin.
