Abstract

This research aims to examine and study the red-producing plants and color stability differences based on the structure of the compounds. The method used is library studies. The results of the study, obtained that plants that produce red substances and used as dyes on fabrics/threads in the production of woven fabrics namely teak (Tectona grandis L.f), mengkudu (Morinda citrifolia L. ), secang (Caesalpinia sappan L.), kesumba keling (Bixa orellana L) and mangosteen (Garcinia mangostana L.). The content of compounds in teak plants is sianidin which has a compound structure in the form of closed chains, the content of compounds in secang is brazilein (C16H14O5) has a closed chain compound structure, the rivet plant contains bixin compound (C25H30O4) which has an open chain structure, mangosteen plant contains cyanidin 3-glucoside (C21H21O11Cl) and cyanidin 3-sophoroside (C27H31O16Cl), contains morindon compounds (C15H10O8) that have closed chain compound receipts, Dragon fruit contains betasianin chemical compounds, rosella flowers contain chemical compounds delphinidin-3- sambubioside, cyanidin-3-sambubioside, cyanidin-3-glucoside and delphinidin-3- glucoside and henna nails contain lawsone (C10H6O3) (2-hydroxy-1,4-napthoquinone).
