Abstract
A new dimeric phthalide, chaxiongnolide A (1), and a new natural product, chaxiongnolide B (2), together with a known compound Z-ligustilide (3), were isolated from the rhizome of Ligusticum sinense Oliv cv. Chaxiong. Their structures were elucidated by various spectroscopic methods and confirmed by X-ray crystallographic analysis.
Keywords:
chaxiongnolide A; chaxiongnolide B; dimeric phthalides; Ligusticum sinense Oliv cv. Chaxiong.
