Abstract

Sunscreen is needed as protection against the skin from exposure to UV rays, because it will cause erythema, aging skin, blistering, and skin cancer, in skin that is not protected by sunscreen. This study aims to determine the in vitro and in vivo ability of epicarpium A. heterophyllus extract sunscreen cream preparations. This research was conducted in vitro and in vivo, beginning with the extraction process with the maceration method using 70% ethanol, identification of compounds in the extract, TLC, GC-MS, total flavonoids test, physical quality of cream preparations, SPF values ​​of extracts and creams, and in vivo sunscreen activity tests were conducted. The yield percentage produced from 450 grams of simplicia powder was 47.61%. The compounds in A. heterophyllus epicarpium extract are flavonoids, tannins, saponins, terpenoids, steroids, fatty acid groups, alcohol groups, and alkanes. Crude extract contains total flavonoids of 43.625 mgQE / g extract. The 75% concentration in the cream preparation had the highest SPF value of 8.173. The in vivo test used the MED (Minimal Erythema Dose) method of erythema scoring. A concentration of 75% gives the lowest MED value of 0.25. This research is expected to provide information on alternative uses of natural ingredients as the main ingredient of sunscreen so that the use of chemicals as the main ingredient will be reduced.

Abstract

Inflammation is protective response of vascular tissue to various harmful stimuli that characterized by pain, redness, and swelling. Empirically, stem bark of Ceiba pentandra has various chemical compounds that nutritious for health and have potential to be used as anti-inflammatory. This research will provide information the benefit of C. pentandra stem bark especially as anti-inflammatory agents and it’s correlation with the compounds. Maceration method with 70% ethanol was used in extraction and the yield was 75,54%. In phytochemical test, it was identified in crude extract contained flavonoids, tannins, saponins, steroids, β-sitosterol, 1,2-benzendiol, quinic acid, and octadec-9-enoic acid. On extract and ointment products C. pentandra has antioxidants activity with IC50 value of extract was 52,64 ppm and IC50 value of ointment products was 117,64 ppm. This research is included RAL experimental which was carried out on male mice that divided into 5 groups: negative control (ointment base), positive control (Betametasone valerate 0,1%), and 50%, 75%, 100% of C. pentandra ointment. The ointment was applied after the mice were induced by carrageenan, measured with the parameter of skinfold thickness of mice’s back every hour for 6 hours of observation. The result showed C. pentandra stem bark ointments has anti-inflammatory effect which %PI value in the 50%, 75%, 100% were respectively 10,85%; 18,99%; 30,84%.

Abstract

The purpose of this study is to determine the potential extract of areca nut (Areca catechu L.) seeds, skin and the combination of the two extracts in killing the Aedes aegypti larvae. This study used a Completely Randomized Design in the seed extract test with a concentration of 16000, 17000, 18000, 19000 and 20000 ppm and skin extract with concentrations of 7000, 8000, 9000, 10000 and 11000 ppm. The factorial design was used in the combined extract of 0:100; 25:75; 50:50; 75:25 and 100:0. Each treatment used 4 replications. Data were analyzed by ANOVA and then continued by Tukey, LSD and Duncan tests. The last, data were analyzed by probit analysis to determine LC50 and LC90. The result indicates that areca nut seed and skin contain flavonoid, alkaloid, palmitic acid, phenols, terpenoids and steroids which are toxic. The killing power of seed extract was 64-97% (24hours) and 100% in all treatments (48hours). Skin extract was 52-88% (24hours) and 58-93% (48hours), while the combination extract was 55 -93% (24hours) and 95-100% (48hours). Concentration of 19000 ppm of seed extract with 95% mortality at 24 hours was effective when compared to the WHO standard (2005), while the skin extract had a lower LC value than the other two extracts.
