Abstract:
Investigation of the extract of Tillandsia usneoides afforded 26 cycloartane derivatives, including the following novel ones: (22E)-25,26,27- trisnor-3-oxocycloart-22-en-24-al, (24E)-3-oxocycloart-24-en-26-al, 24- hydroxycycloart-25-en-3-one, (23E)-25-methoxycycloart-23-en-3-one, (23E)-25- hydroperoxycycloart-23-en-3-one, 25,26,27-trisnor-24-hydroxycycloartan-3- one, methyl (24E)-26-carboxy-3,4-seco-cycloart-4(29),24-dien-3-oate, methyl (23E)-25-hydroxy-3,4-seco-cycloart-23-en-3-oate, methyl (23E)-25-methoxy- 3,4-seco-cycloart-23-en-3-oate, and methyl 24-hydroxy-3,4-seco-cycloart-25- en-3-oate. The structures were assigned on the basis of spectral data.
