Chemistry—"The essential oil from yellow champaca flowers (Michelia champaca L.) has the specific gravity 0.904—0.9107 at 30°/30° C., nD=1.4640—1.4688 at 30°C, ester value 124—146, and ester value after acetylating 199. When distilled in a vacuum it polymerises. It contains isoeugenol, benzoic acid, benzyl alcohol, benzaldehyde, cineol and p-cresol methyl ether. The white flowers (Michelia longifolia BI.) yield an oil with the following characters:—specific gravity 0.897, ester value 180.0, uD=1.4470 at 30°C. It contains linalool, methyleugnol, methylethylactic acid probably in the form of the methyl or ethyl ester, and a phenolic substance possessing an odour closely resembling that of thymol. The yellow flowers contain a ketone inciting at 165°—166°C., and yielding ahydrazone C16, H20 04: N. N.H C6. H5, m. pt. 161°C."—J. Ch. I. Jan. 31st, 1912, p. 90.
