Abstract
The results of the analysis of volatile oil obtained from galls caused by Sacchiphantes viridis are presented in this paper. It was found that galls contain more oil than normal shoots. The composition of the oil obtained from galls differs significantly from that of normal shoots. The differences observed in the amount of camphene. β-pinene, myrcene, 3-carene, unidentinfied compounds 14 and 17, camphor, fenchyl alcohol, borneol and citronellol seem to be connected with the deterioration of central resin canals in the stem cortex during the development of galls and with the formation of new and very numerous canals in the bases of the differentiated gall leaves.
