Tokinolide B may have sedative and spasmolytic properties.

The chemical constituents of the organic extracts from the rhizomes of Ligusticum porteri were isolated, characterised and identified as Z-ligustilide, Z-butylidenephthalide, diligustilide, Tokinolide B, riligustilide, senkyunolides F and I, ferulic acid, among other known compounds. The preparation of 4,5-dehydroTokinolide B from Tokinolide B is reported, and its structure confirmed by X-ray analysis. The sedative and spasmolytic activities of some of these natural products and derivatives were evaluated by applying them to in vivo and in vitro models.
