Three new 3-hydroxy-3-methylglutaryl (HMG) flavone 7-O-diglycosides, argutosides A-C (1-3); two new flavone 7-O-triglycosides, argutosides D-E (4-5); and one known apigenin 7-O-triglycoside (6), were isolated from the leaves of Turpinia arguta. The structures of these compounds were elucidated by spectroscopic and chemical techniques. The NO inhibitory activities of compounds 1-6 were evaluated using lipopolysaccharide-induced RAW264.7 cells. Only compound 2 showed a moderate inhibitory effect on NO production with an IC value of 25.74μM. Compounds 1-6 were not cytotoxic to RAW264.7 cells at 10μM.
从山香圆叶中分离得到3个新的3-羟基-3-甲基戊二酰（HMG）黄酮7-O-二糖苷，即山香圆苷A - C（1 - 3）；2个新的黄酮7-O-三糖苷，即山香圆苷D - E（4 - 5）；以及1个已知的芹菜素7-O-三糖苷（6）。通过光谱和化学技术阐明了这些化合物的结构。使用脂多糖诱导的RAW264.7细胞评估了化合物1 - 6的一氧化氮（NO）抑制活性。只有化合物2对NO生成表现出中等抑制作用，IC值为25.74μM。化合物1 - 6在10μM时对RAW264.7细胞无细胞毒性。
