Bulbous and scapose herbs having a bell-shaped corolla with a
prominent tube and short limb. The plant, probably native to Asia
Minor or the Balkans, is cultivated extensively for ornamental and
extractive purposes, especially in The Netherlands and France. The
part used is the flower.
The derivatives are concrete and absolute. The concrete is extracted
from flowers in approximately 0.13 to 0.22% yields using petroleum
ether. It is a greenish-brown, waxy mass. The absolute, prepared by
alcoholic extraction of the concrete in approximately 10 to 14%
yields, is a viscous, reddish-brown liquid exhibiting a characteristic,
persistent scent of hyacinth flowers.
Hyacinth has a sweet, floral, slightly green, persistent odor similar
to hyacinth flowers.
