CHAPTER 4 RESULTS AND DISCUSSION 4.1 Identification of camphor and menthol using gas chromatography – mass spectrometry (GC – MS) In this study‚ the presence of menthol and camphor were determined from 5 different locally produced medicinal topical ointment samples. Sample of Vick® VapoRub® and Hurix’s Massage Balm were purchased from local pharmacies‚ Bunga Cengkih Balm and Serai Balm samples were purchased from the grocery shop. Buah Pala Balm sample was purchased from the night market

production. However‚ isoborneol is more toxic than borneol and thus is not favored regarding the safety issue of drugs. But how can we synthesize borneol in a way that gives more borneol than toxic isoborneol? An experiment of making borneol from camphor (FIGURE-3) is performed in two different methods‚ Sodium Borohydride Reduction and Meerwein-Ponndorf-Verley Reduction‚ to compare the relative product ratio of borneol to isoborneol. The concept of reduction and also oxidation‚ the opposite procedure
