Two new flavonoids, abutilin A and B, were isolated from the chloroform soluble fraction of Abutilon pakistanicum and their structures assigned from (1)H and (13)C NMR spectra, DEPT and by 2D COSY, HMQC and HMBC experiments. Ferulic acid (3), (E)-cinnamic acid (4), 5-hydroxy-4',6,7,8-tetramethoxyflavone (5), kaempferol (6), luteolin (7) and luteolin 7-O-beta-D-glucopyranoside (8) have also been reported from this species.
从苘麻（Abutilon pakistanicum）的氯仿可溶部分分离得到两个新的类黄酮，分别命名为 abutilin A 和 B，并通过（1）H 和（13）C NMR 谱、DEPT 以及 2D COSY、HMQC 和 HMBC 实验确定了它们的结构。还从该种植物中分离得到阿魏酸（3）、（E）-肉桂酸（4）、5-羟基-4'，6，7，8-四甲氧基黄酮（5）、山柰酚（6）、木樨草素（7）和木樨草素 7-O-β-D-吡喃葡萄糖苷（8）。
