Abstract

This   research   with   the   title   Thin   Layer   Chromatography  for Determination of Hesperidins Content in Orange Peel has been done in organic chemistry laboratory. The aim of this research is to select the solvent mix for  the best hesperidins standard peak result and to determinate the content (in relative percentage) of some orange peel. Hesperidins isolation from  orange peel conduct by soaks the orange peel piece  in f 0% Calcium hydroxide solution for  a night in room temperature.    The   mixture   than  jiltered    and   neutralized   with hydrochloric acid to obtain hesperidins contain filtrate.  Hesperidins analyzed   by   thin   layer   chromatography.    Characterization   of hesperidins did by compare the sample chromatogram with standard chromatogram.  The yield  (in  relative  percentage)   determinate  by  compare the sample peak area with hesperidins standard peak area. The solvent  mix  selected  before  by  attempt  some  solvent  mix for eludate hesperidins standard solution. The result of this research shown that hesperidins can analyzed using thin   layer   chromatography   method.   with   the   best  solvent   was chloroform:  methanol mixture (2 : 3). Hesperidins content in extract solution of some strain orange peel  is; Baby Egypt 0, f 380%, Baby Pacitan 0,0615%, Mandarin Lokam 0,0018%, Santang 0,0049%, and Sunkist  Nevel 0,0360%.  The hesperidins  content  in orange peel  of Mandarin Pakistan, Medan super, Nipis, Sunkist,  Peras, and Purut was 0,0000. The hesperidins content in these orange peel was too low to be detected

Abstract

Guava leaves have flavonoids, tannins, and alkaloids as main compounds which have been shown to be active as antibacterial and anticarcinogenic agents. However, they have never been used as additives in skin care products because they have a rough texture. The purpose of this research are to formulate the method in the production of bath soap with the leaves as additives, and they were examined in quality and organoleptic tests. Formulation in production of the soap was carried out by means of variations of the method of extracting guava leaves as additives, namely: without additive as a control (A), with water solvent (B), with vegetable oil solvent (C), and powder dried as a scrub (D). The soap quality tests based on SNI 2016 including tests for alkaline or free fatty acid levels, insoluble ingredients in ethanol and unsaponified fat fractions. Organoleptic test was carried out involving 20 panelists. Data were analyzed by ANOVA-Duncan test. It was found that soap quality test for all samples meet INS except free alkali levels in D soap. The hedonic test results show that all soap samples can be accepted by panelists. Based on quality and organoleptic tests, the formulation method for adding guava leaf extract as an additive that produces the best soap is extraction using a water solvent (soap B). For the next study, it is necessary to confirm the biological activity of soap with guava leaf additives because it is very potential to be used as an antimicrobial soap.
