Abstract

Clidemia hirta is an invasive plant that can inhibit other species around it. This plant is often found and grows wild throughout the gardens in the village of Kemuning, Ngargoyoso, Karanganyar. This study aims to determine the bioactive compounds from the C. hirta plant which have the potential as natural dyes and ecoprints. The results showed that there were 15 compounds from C. hirta leaves, one of which was a phytol compound (alcohol diterpenoid) which was included in the terpene group. This compound has the potential as a natural dye because it has an important role as the main constituent of chlorophyll. However, when tested as a dye it did not produce color on the fabric, due to several reasons such as the inappropriate ratio of the number of leaves to water during the boiling stage and the color binding process which was not perfect. When testing the ecoprint with the steam technique, the brown color appears, it is possible that the phytol compounds that produce the green color have been oxidized with oxygen so that the color turns dark. This research was conducted at the Microbiology Laboratory, Faculty of Teaching and Education, Sebelas Maret University. The Gas chromatography-mass spectrometry (GC-MS) method was carried out at the Jakarta Special Capital Region Health Laboratory from June to July 2023.
