Conclusions

A new coumarin obtusifol, C₁₅H₁₆O₆, with mp 149.5–150°C has been isolated fromHaplophyllum obtusifolium for the first time.

The structure of 2′- or 3′-(1-hydroxy-1-methylethyl)-8-methoxy[1,4]dioxano[g]coumarin has been proposed for obtusifol.

It has been shown that the genusHaplophyllum is close in respect of its coumarin composition to the genusPtaeroxylon.
