Physical properties
The essential oil of B. alba L. is a viscous, yellow liquid with a balsamic odor. It is obtained
from buds by steam distillation in 3.5 to 8% yields. The oil solidifies at low temperature because of its paraffin content. The essential
oil of B. alba L. var. pubescens Ehrl., obtained from buds in 3.5% yields by steam distillation, has a specific gravity of 0.9779. The
essential oil of B. alba I. obtained from bark is recovered in 0.4 to 0.5% yields. The essential oil obtained from leaves is recovered
in 0.4 to 0.5% yields.
