[Chemical Constituents of Petroleum Ether Fraction of Lonicera macranthoides Roots].
OBJECTIVE
To study chemical constituents of petroleum ether fraction of the roots of Lonicera macranthoides.


METHODS
The chemical constituents were isolated and purified by several separation and purification techniques and their structures were elucidated by physicochemical properties and spectroscopic methods.


RESULTS
Six compounds were isolated from petroleum ether fraction of the roots of Lonicera macranthoides as 3α, 16β-dihydroxyaphidicolane (1), (22E,24R)-ergosta-6,9,22-trien-3β,5α,8α-triol (2), (22E)-5α,8α-epidioxyergosta-6,22-dien-3β-ol (3), (24S)-stigmast-4-en-3-one (4), β-amyrin (5) and β-amyrin acetate (6).


CONCLUSIONS
Compounds 1 ~ 3 and 6 are isolated from this genus for the first time. All the compounds are isolated from this plant for the first time. Compound 1 is a new natural product.
