W. Kiridena et al., DETERMINATION OF ALOIN AND ALOE-EMODIN IN ALOE CONSUMABLE PRODUCTS BYTHIN-LAYER CHROMATOGRAPHY, JPC. Journal of planar chromatography, modern TLC, 8(6), 1995, pp. 416-419
Aloin and aloe-emodin can he isolated from Aloe leaf products by solve
nt-assisted supercritical fluid extraction and determined by silica ge
l thin layer chromatography, using automated multiple development for
aloin and normal development for aloe-emodin, with the solvent systems
described, The methods proposed are suitable for the screening of Alo
e leaf products for human consumption to ascertain conformation with r
egulatory requirements.
