Abstract

Indonesia has high sun exposure, and most people work outdoors, so they need skin protection. One plant with the potential as a sunscreen is matoa leaf (Pometia pinnata). This study aimed to determine the physical quality and the Sun Protecting Factor (SPF) value of matoa leaf ethanol extract lotion, which were analyzed in vitro. Physical quality evaluation included organoleptic tests, homogeneity, pH, adhesion and spreadability, and SPF values obtained by the UV-Vis spectrophotometry method. Mansur Formula was used to calculate the SPF value. The results of the study showed FI (0.5%), FII (1%), and FIII (1.5%) obtained an average SPF value of 13.99 ± 1.45 (maximum protection), 22.27 ± 2.06 (ultra protection), 27.42 ± 0.54 (ultra protection). All formulas had good physical quality and had potential as sunscreens.  Key words: lotion; matoa leaves; SPF; sunscreen

Abstract

This study investigates Bungkus leaf (Smilax rotundifolia), a well-known plant in Papua commonly referred to as the three-finger leaf. Indigenous Papuans traditionally use this plant to enlarge genitals, buttocks, and breasts, as well as to treat syphilis. The plant is known to contain flavonoid and phenolic compounds with pharmacological activity. This study aimed to determine the total flavonoid and total phenolic content of the 70% ethanol extract of Bungkus leaf. The research began with simplicia preparation, followed by extraction using 70% ethanol. Qualitative tests, including phytochemical screening and thin-layer chromatography (TLC), were conducted, followed by quantitative analysis using UV-Vis spectrophotometry. The results showed total flavonoid content of 54.696 mg QE/g ± 0.565 and total phenolic content of 32.908 mg GAE/g ± 0.263. The study concluded that the total flavonoid content was higher than the total phenolic content. Toxicity testing categorized the extract as toxic, with an LC50 value of 442.92 ppm.

Abstract

This study investigates the anti-inflammatory properties of an ethanol extract from Jabon plant stem bark in male mice using the Rat Hind Paw Edema method. Twenty-five male mice were divided into five groups: negative control (Na-CMC 1%), positive control (mefenamic acid), and three groups receiving the extract at doses of 50 mg/kg, 100 mg/kg, and 200 mg/kg. Measurements were taken every 30 minutes for three hours using a plethysmometer. Analysis with one-way ANOVA and Duncan's test revealed significant anti-inflammatory effects for all doses, with the most effective being 100 mg/kg, showing 93.42% inhibition. The results suggest Jabon plant extract as a promising anti-inflammatory agent.
