Abstract

Tea tree is an essential oil-producing plant from Australia which is also found growing in several parts of Indonesia, including the island of Lombok. So far, tea tree essential oil producers on the island of Lombok do not utilize by-products in the form of hydrosol (distilled water) produced in the process of making essential oils. In this study, the characterization and analysis of the chemical composition of the hydrosol of tea tree leaves growing on the island of Lombok was carried out. The characteristic aroma of hydrosol is similar to that of tea tree essential oil. The results of the GC-MS analysis also showed that the hydrosol of tea tree leaves also had similarities with the essential oil, composed of major compounds in the form of trans-caryophyllene (28.58%), limonene (13.98%) and terpinen-4-ol (16.27%). Other compounds detected were -pinene (4.14%), -pinene (6.50%), -myrcene (8.09%), -terpineol (10.10%) and -terpinene (5.77%).

Abstract

Moringa (Moringa oleifera L.) is a plant belonging to the moringaceae family. Moringa seeds contain oil which can be used as a raw material for making azelaic acid. Azelaic acid is used as an anti-acne in the pharmaceutical and cosmetic industries. Azelaic acid can be obtained from the oxidation process of fatty acids in moringa seed oil using potassium permanganate as an oxidizing agent. The resulting azelaic acid is in the form of white crystals with a conversion percentage of 72.17%. The results of the FT-IR characterization showed the formation of azelaic acid characterized by widening of the hydroxyl group at 3448.46 cm-1 followed by a shift of the ester group at absorption of 1633.46 cm-1. The ester bond is strengthened at a wavelength of 1115.95 cm-1.
