We examined the modifying effect of whole-leaf Aloe arborescens Miller var. natalensis Berger (designated as 'ALOE') on azoxymethane (AOM)-induced aberrant crypt foci (ACF), putative preneoplastic lesions, in the rat colorectum. Male F344 rats (4 weeks old) were fed the basal

In 0.1 mol.L-1 H2SO4 solution, a well-defined reduction wave of barbaloin was obtained by single-sweep osciflopolarography. The peak potential was shown to be -0.75 V (vs SCE). The peak current is proportional to the concentration of barbaloin over the range

A strictly anaerobic bacterium, Eubacterium sp. BAR, was isolated from human feces as one of the intestinal bacteria capable of metabolizing barbaloin. The bacterium grew in PYF broth containing barbaloin and converted barbaloin to aloe-emodin anthrone. On the other hand

The contents of barbaloin (BA), isoBA, aloin-dimers A, B, C, D and aloe-emodin (AE) in aloe drinks were investigated. BA and isoBA were detected in 30 of the 31 samples at the levels of 120-570 micrograms/mL and 120-580 micrograms/mL, respectively.

Charcoal transport, as an indicator of the degree of peristalsis, and water content in the large intestine after the intracaecal administration of barbaloin, were measured simultaneously in the same rat. Charcoal transport was significantly accelerated at both 3.5 and 6.5
