树兰烯是树兰(又名米仔兰,学名Aglaia odorata Lour,楝科)花精油中的倍半萜烯成分之一,含量约10％。可以结合分馏及反复的柱层析来分离提纯。所得气液色谱纯及薄层色谱纯的树兰烯具有下列物理常数:沸点82℃/3毫米,n_D~(14)1.4958;n_D~(20)1.4890;d_4~(16)0.9190,d_4~(20)0.9086;[α]_D~(27)-1.5°(液体)与已知的倍半萜烯的物理常数均不完全符合,其红外光谱亦与当时(1963年前)已知的倍半萜烯不同。
Echinacolone is one of the sesquiterpene constituents in the essential oil of Agaveria (also known as Aglaia odorata Lour, Meliaceae), in an amount of about 10%. Can be combined with fractionation and repeated column chromatography to separate and purify. The obtained gas chromatographic pure and thin-layer chromatographic pure eugenylenes have the following physical constants: boiling point 82 ° C / 3 mm, n_D ~ (14) 1.4958; n_D ~ (20) 1.4890; d_4 ~ (16) 0.9190, d_4 ~ 20) 0.9086. The [α] _D ~ (27) -1.5 ° (liquid) did not completely match the physical constants of the known sesquiterpenes. The IR spectra were also similar to those known at that time (before 1963) Different terpenes.
