EXTRACTION OF VOLATILE OIL FROM LOPHANTHUS ANISATUS BENTH. AND STUDY OF ITS CHEMICAL COMPOSITIONS
The results of experimental studies on the extraction of volatile oil from Lophanthus anisatus Benth., a new plant in Russia, is presented. The content of volatile oil from the plant depends on the period of vegetation, the variety of Lophanthus anisatus Benth., and the type of top part of plants. It is found that the highest yield of volatile oil obtained by steam distillation comes from the plant blossoms. Some physical-chemical constants of volatile oil (refractive index and density) have been identified. The composition of volatile oil of Lophanthus anisatus Benth. has been studied by quantitative method of gas-liquid chromatography; it is shown that it is practically not dependent on the variety of Lophanthus anisatus Benth. and the type of the top part.
