Chemical constituents from Abutilon indicum

Abstract

The investigation on the chemical constituents of the whole plant of Abutilon indicum has resulted in the isolation of two new compounds, abutilin A (1) and (R)-N-(1′-methoxycarbonyl-2′-phenylethyl)-4-hydroxybenzamide (2), as well as 28 known compounds. The structures of the two new compounds were established on the basis of the spectroscopic analysis, and the known compounds were identified by comparison of their spectroscopic and physical data with those reported in the literature.

Keywords:

• Abutilon indicum
• Malvaceae
• biphenyl ether
