[Chemical constituents from roots of Ardisia punctata].
OBJECTIVE
To study the chemical constituents from the roots of Ardisia punctata.


METHODS
Compounds were isolated by chromatographic techniques on silica gel and Rp-HPLC column. Their structures were elucidated by chemical and spectroscopic methods.


RESULTS
Twelve compounds were identified as 3-hydroxy-5-tridecyl-methyl phenyl ether (1), 5-pentadecyl-1, 3-benzenediol (2), 2-methoxy-6-tridecyl-1, 4-benzoquinone (3), 2-methoxy-6-pentadecyl-1, 4-benzoquinone (4), glutinol (5), ardisicrenoside A (6), ardisiacrispin B (7), 24-ethyl-5a-cholesta-7, 22(E)-dien-3-one (8), 24-ethyl-5alpha-cholesta-7, 22(E)-dien-3beta-ol (9), daucosterol (10), vanillin acid (11), tetratriacontanoic acid (12).


CONCLUSIONS
All the compounds were obtained from this plant for the first time.
