(1) Aloin and aloeemodin do not influence directly the ribosomes, but they inhibit elongation factors and peptidyltransferase activities in the complete elongation system.
(2) Aloin and aloeemodin are responsible for the inhibitory effect of the solution of dry aloe extract.
(3) A simple and rapid liquid chromatographic method is described for the determination of barbaloin (aloin, 10-D-glucopyranosyl-1,8-dihydroxy-3-(hydroxymethyl)-9(10H)-anthraceno ne) in foods.
(4) A purified sample of aloe emodin was prepared from aloin, and its effects on the infectivity of herpes simplex virus type 1 and type 2, varicella-zoster virus, pseudorabies virus, influenza virus, adenovirus, and rhinovirus were tested by mixing virus with dilutions of aloe emodin for 15 min at 37 degrees C, immediately diluting the sample, and assaying the amount of infectious virus remaining in the sample.
