摘要：

The roots of Bulbine capitata yielded five new compounds, 2-hydroxy-3-methoxy-5-(2-propenyl) phenol, 5,8-dihydroxy-1-methylnaphtho[2,3-c]furan-4,9-dione, 5-hydroxy-8-methoxy- or -8-hydroxy-5-methoxy-1-methylnaphtho[2, 3-c]furan-4,9-dione, 5,8-dihydroxy-1-hydroxymethylnaphtho[2,3-c]furan-4,9-dione and knipholone-6'-methyl ether in addition to the known compounds 8-hydroxy-1-methylnaphtho[2,3-c] furan-4,9-dione, chrysophanol, 10,10'-chrysophanol bianthrone, knipholone and isoknipholone. The structures were determined on the basis of spectroscopic data. (C) 1997 Elsevier Science Ltd.
