AAL, also known as A'l, Ach, or Aich, the Hindustani names for the Morinda tinctoria and Morinda citrifolia, plants extensively cultivated in India on account of the reddish dye-stuff which their roots contain. The name is also applied to the dye, but the common trade name is Suranji. Its properties are due to the presence of a glucoside known as Morindin, which is compounded from glucose and probably a trioxy-methyl-anthraquinone.
