(Z)-6-6--7-3-a-Diligustilide and ferulic-acid

To study the chemical constituents of the root and rhizoma of Ligusticum jeholense.. The constituents were isolated by silica gel column chromatography, Sephadex LH-20 column chromatography and their structures were elucidated through spectral analysis.. Seven compounds were separated from the EtOH extracts. Their structures were identified as levistolide A (1), xiongterpene (2), linoleic acid (3), sucrose (4), daucosterol (5), ferulic acid (6) and beta-sitosterol (7).. Compounds 1-5 are isolated from the genus for the first time.

To study the chemical constituents from dry roots of Ligusticum glaucescens Franch.. Chromatography and spectrum analysis were employed to isolate and elucidate the chemical constituents in the plant.. 4 compounds were isolated and identified as levistolide A (I), ligustilide (II), pleuchiol (III) and ferulic acid (IV).. I-IV were isolated from this plant for the first time. The work provided evidence for the exploitation and utilization of this plant resource.
