Abstract
Five new phthalides (1-4, 6), two new natural products (5, 7) and five known phthalides (8-12) were isolated from the aerial parts of Ligusticum sinense Oliv cv. Chaxiong. Their structures were elucidated by HR-ESI-MS, UV, IR, 1D and 2D NMR (HSQC, HMBC, (1)H-(1)H COSY, NOESY) methods. The absolute configurations were established by the circular dichroism (CD) spectrum and the modified Mosher's method. Compounds 1-8 were tested against SK-N-SH cell depriving oxygen and glucose and showed different degrees of increasing the cell survival, among which compounds 1, 4 and 8 (10 μM) showed higher cell survival than Ginsenoside Rg1.Entities:
