Identifikasi dan Fotodegradasi Pigmen Klorofil Rumput Laut Caulerpa racemosa (Forsskal) J.Agardh
Abstract: Identification of
chlorophyll compound of Caulerpa racemosa has been carried out using Thin Layer
Chromatography (TLC) method. Four compound has been found namely xanthophll,
chlorophyll b, chlorophyll a, and phaeophytin. Xanthophyll was identified with the
yellow spot on TLC plates which the Rf is 0,46. Chlorophyll b is yellow green
spot with Rf is 0,61, the Rf of Chlorophyll a is 0,69 with the color is blue
green, whereas phaeophytin is indicated as a black spot with the Rf 0,77. Volpi
and UV light sources were used in this study, the volpi light radiation was
caused chlorophyll extract degradation about 80,87% at Qy of 663 nm, and the
UV light source caused 72,27% degradation at 663 nm.
