Two novel monoterpenes, sibiscolacton (1) and sibiraic acid (2), were isolated from the aerial part of Sibiraea angustata Rchd. along with seven known compounds, namely three phenylpropanoids (3–5), two flavonoids (6,7), one glucityl ferulate (8, sibirate), and a monoterpene glucoside (9, sibiskoside). The structures of 1 and 2 were established on the basis of spectroscopic and chemical data.
从Sibiraea angustata R chd的地上部分分离出两种新的单萜,sibiscolacton ( 1 ) 和 sibiraic acid ( 2 ) 。连同七种已知化合物,即三种苯丙烷类化合物( 3 – 5 )、两种黄酮类化合物 ( 6 , 7 )、一种阿魏酸葡萄糖酯 ( 8 , sibirate) 和一种单萜糖苷 ( 9 , sibiskoside)。1和2的结构是在光谱和化学数据的基础上建立的。
