Chemical properties of aloe

According to W. A. Shenstone, two classes of aloins are to be recognized: (1) nataloins, which yield picric and oxalic acids with nitric acid, and do not give a red coloration with nitric acid; and (2) barbaloins, which yield aloetic acid (C₇H₂N₃O₅), chrysammic acid (C₇H₂N₂O₆), picric and oxalic acids with nitric acid, being reddened by the acid. This second group may be divided into a-barbaloins, obtained from Barbadoes aloes, and reddened in the cold, and b-barbaloins, obtained from Socotrine and Zanzibar aloes, reddened by ordinary nitric acid only when warmed or by fuming acid in the cold. Nataloin (2C₁₇H₁₃O₇·H₂O) forms bright yellow scales. Barbaloin (C₁₇H₁₈O₇) prismatic crystals. Aloes also contain a trace of volatile oil, to which its odour is due.^{[citation needed]} Image File history File linksMetadata Download high resolution version (1512x2016, 540 KB) Permission is granted to copy, distribute and/or modify this document under the terms of the GNU Free Documentation License, Version 1. ...
