Conclusions From the roots ofXanthogalum purpurascens growing in the Transcaucasus, we have isolated a new coumarin, C24H26O7 with mp 111–113°C, [α] D 20 −164.2° (c 0.97; ethanol) which we have called xanthalin. On the basis of the NMR spectrum it has been established that xanthalin is 3′, 4′-diangeloyl-2′, 2′-dimethyl-3′, 4′-dihydropyrano-5′, 6′:6, 7-coumarin.
