Abstract

ABSTRACT Sweet orange peel (Citrus x sinensis) has benefits as an antioxidant and Sun Protecting Factor (SPF). This study aims to determine the antioxidant activity of sweet orange peel extract with 70% and 90% ethanol solvent variations using the Sun Protecting Factor (SPF) method. Sweet orange peel (Citrus x sinensis) was extracted using maceration method with 70% ethanol and 90% ethanol as solvent variations. The extract was then concentrated using a water bath. The extracts obtained were tested for phytochemicals for alkaloids, flavonoids, tannins, saponins and triterpenoids. The antioxidant activity test was carried out by dissolving each extract in absolute alcohol with a concentration of 20% (w/v). Antioxidant activity test using Sun Protecting Factor (SPF) method using UV-Vis spectrophotometer. The data was processed using One-Way Anova test statistics. The phytochemical test results on sweet orange peel extract showed that the extract contained positive alkaloids, flavonoids, saponins, tannins and triterpenoids. The antioxidant activity test on sweet orange peel extract showed that 70% alcohol solvent had a higher SPF value of 20,95, while the extract with 90% alcohol solvent had a lower SPF value of 15,70. Keywords: Citrus x sinensis, extract, maceration, UV-Vis spectrophotometer, SPF.

Abstract

Abstract White Tumeric (Curcuma zedoaria) is a plant that contains curcuminoid compounds and essential oils on its rhizomes which are useful as anticancer. The purpose of this study is to find out which type of filling material (diluent) is good as a filler for white meeting tablets (Curcuma zedoaria). Tablets are made using the direct printing method with the types of fillers (diluent) used are ludipress, starch 1500, and Spray Dried Lactose. The resulting tablets were carried out still angle and flow properties tests, compression index tests, weight uniformity tests, size uniformity tests, tablet hardness tests, tablet brittleness tests, and crush time tests. In the test of stationary angle and flow properties and compression index in ludipress filler materials, the flow property value was 10.42 g/s, the stationary angle value was 27.77º, and the compression index was 10%. In the starch filler material 1500 obtained a flow property value of 4.17 g / s, a stationary angle of 34.40º, and a compression index of 30%, in the formulation of Spray Dried Lactose obtained a flow property value of 10.18 g/s, a stationary angle of 27.74º, and a compression index of 5%. Variations of the type of diluent Spray Dried Lactose show optimal results for white temu tablet filler (Curcuma zedoaria).
