Onion peel contains flavonoid and phenolic compounds that have potential as antioxidants; however, they have limitations in stability and bioavailability. Onion peel extract has a dark red color and a characteristic onion peel odor, with moisture content, water-soluble extractive content, ethanol-soluble extractive content, and total ash content of 7.33% ± 0.577; 35.33% ± 2.01; 80.8% ± 2.49;…
Red onion peels (Allium cepa L.) contain quercetin flavonoid compounds that serve antihyperlipidemic activity. This study aimed to formulate phytosome preparations of shallot peel extract and evaluate their characteristics as well as their antihyperlipidemic activity in vivo. The phytosomes were prepared using variations of extract and phosphatidylcholine ratios by the thin-layer hydration meth…
Red onion peels (Allium cepa L.) contain flavonoid, phenolic, and steroid compounds that serve as potential antioxidants. This study aimed to optimize the concentration of polymers and crosslinking agents in a nanosuspension formulation of red onion peel extract prepared using the ionic gelation method. Optimization was conducted using a 22 Factorial Design in Design-Expert 13® software, evalu…
The red onion (Allium cepa L.) have a skin that contained active compounds such as flavonoids, steroids, and phenolics that have the potential as antioxidants, one of which can be used as a hair growth stimulant. This study aimed to optimize the use of gelling agents in hair serum formulations of red onion peel extract (Allium cepa L.) as a hair growth stimulant. The formula optimization was de…
Red onion skin (Allium cepa L.) has been proven to promote hair growth due to its strong antioxidant activity. Transfersomes were capable of penetrating the transfollicular pathways to enhance the antioxidant effect of quercetin compounds in red onion skin extract. This study aims to optimize the transfersome formula of red onion skin extract by varying the concentrations of phospholipon 90G an…
This study aims to determine the effect of shallot peel extract on the growth of pepper cuttings (Piper nigrum L.). This study used an experimental method with Completely Randomized Design (CRD) which consist of six treatments and four replication. The treatments consisted of shallot peel solution 0% (P0), 60% (P1), 70% (P2), 75% (P3), 85% (P4), and synthetic Plant Growth Regulator (PGR) (P5). …
