Objective:
To study the phenolic constituents of the leaves of pineapple.
Method:
Chromatographic methods were used to isolate compounds from the leaves of pineapple and spectroscopic methods were used to identify the structures of the isolated compounds.
Result:
7 compounds, ananasate (1), 1-O-caffeoylglycerol (2), 1-O-p-coumaroylglycerol (3), caffeic acid (4), p-coumaric acid (5), beta-sitosterol (6) and daucosterol (7), were isolated from the leaves of pineapple.
Conclusion:
1 was a new compound, and others were obtained from this plant for the first time.
