[Study on the chemical constituents of the leaves of Ipomoea batatas].
OBJECTIVE
To study the chemical constituents of the leaves of Ipomoea batatas.


METHODS
The constituents were isolated and purified by silica gel and TLC, and their structures were elucidated by spectroscopy.


RESULTS
Six compounds were isolated from 90% ethanol extract and identified as tetracosane (I ), myristic acid (II), beta-sitosterol (II), beta-carotene (IV), daucosterol (V) and quercetin (VI).


CONCLUSIONS
Compounds I, II, IV, V are isolated from this plant for the first time.
