Kulit buah nanas (Ananas comosus (L.) Merr.) dan kulit mangga (Mangifera indica L.) mengandung senyawa polifenol yang memiliki aktivitas antioksidan penghambat tirosinase. Kedua tersebut bermanfaat untuk pencerah kulit. Tujuan penelitian ini mengetahui nilai tirosinase dari masing-masing ekstrak (EKBN) (EKBM), serta kombinasinya dengan rasio 2:1; 1:1; 1:2. Kombinasi memberikan terbaik berpotens...

Pineapple (Ananas comosus L. Merr) is a plant that can live well on nutrient-poor lands such as peatlands. However, resistance to conditions caused by symbiosis with endophytic bacteria capable of growth-promoting (PGPB) through biostimulant and bioprotective mechanisms. This study aims characterize the potential from pineapple roots peatlands biostimulants agents. Thirteen root were characteri...

Studies on a quantitative separation and analysis of chloroplastic matter by different investigators have revealed that chlorophyll is held by chemical forces on proteinaceous matter. This matter, named phyllochlorin by MESTRE (17), chloroplastin by STOLL (37), photosynthin by FRENCH (8), and chloroglobin by RABINOWITCH (21), is presumably identical with the substance composing the stroma of ch...

This report supplements the earlier report (13) which discussed the growth rates, water and mineral nutrient intake by the same group of plants. The data herein considered deal with the chemical composition of the leaf and stem tissues at different growth intervals of pineapple plants grown in nutrient solutions in the greenhouse and in soil under field conditions with different amounts of nitr...

The biosynthesis of nanoparticles has been proposed as a cost effective and environmental friendly alternative to chemical and physical methods. Plant mediated synthesis of nanoparticles is a green chemistry approach that intercomnects nanotechnology and plant biotechnology. In the present study, synthesis of silver nanoparticles (AgNPs) or (Green-Silver) has been demonstrated using extracts of...
