Two new isocoumarins named xyridin A and B were isolated from the chlo
roform extract of the flowering eads of Xyris indica. Their structures
were established as -propyl-6,7-(methylenedioxy)-1H-2-benzopyran-1-on
e and propyl)-6,7-(methylenedioxy)-1H-2-benzopyran-1-one by means of s
pectroscopic analyses.
