Abstract
Novel cyclopentapyran esters are produced from specific plants of the genus Valeriana, i.e. from Valeriana mexicana or Valeriana toluccana. Said esters have a high tranquilizing and sedative effect which is superior to that of known cyclopentapyran esters produced from Valeriana officinales and the like Valeriana species.
