Die Chemie der Natürlichen Ordnung Cupressales. XXXII. Über die Inhaltsstoffe des Kernholzes von Athrotaxis selaginoides Don, Athrotaxis cupressoides Don und Chamaecyparis pisifera Sieb et. Zucc.

Abstract

The constituents of the wood of A. selaginoides and A. cupressoides as well as a neutral oil from the wood of C. pisifera were investigated. From the water soluble fraction of A. selaginoides L-arabinose as well as a new phenolic substance (C17 H18 O7) was isolated. The acid fraction contained high molecular weight crystalline fatty acids. The chief neutral fraction yielded a cardenolide and a cardenolide alcohol. The cardenolide alcohol mixture can be separated chromatographically into crystalline a and 6 fractions and an X cardenolide alcohol can be extracted from these. The distillation residue yielded hinokiol and B-sitosterol. From A. cupressoides an analog of L-arabinose was isolated containing high molecular weight crystalline fatty acids. Cedren, a cardenolide, together with 3 crystalline cardenolides and hinokiol, was also isolated. The neutral oil from C. pisifera contained a cardenolide and 3 crystalline cardenolide alcohols.
