Like other Cinnamomum species, Cinnamomum Tamala, Nees et Eberm., a medium-sized tree widely distributed throughout Southern Asia, yields the so-called Mutterzimt, the Cassia lignea, Xylocassia or Holzcassia, known as cassia in the retail trade. The leaves formerly entered commerce as narrow Folia Mala-bathri, but are now obsolete. However, they are still used for medicinal purposes in the East Indies. They contain a volatile oil which was distilled by j. H. Burkill in Calcutta and examined by Schimmel & Co.5). The oil was lemon-yellow in color and possessed a clove-like and at the same time faintly pepper-like odor. It had the following constants: d15o1,0257; aD+16°37'; nD20o1,52596; phenol content 78p.c; soluble in 1,2 or more vol. of 70 p. c. alcohol. The oil contains eugenol (m. p. of benzoyl derivative 69°). The oil deprived of phenols had a high optical rotation (aD + 66° 40') and yielded a solid nitrite which, after distillation from acetic ether, melted at 113 to 114°. Hence d-a-phellandrene was present. So far as its high eugenol content is concerned, the oil is closely related to the common cinnamon leaf oil.
