| Abstract: | A kind of monoterpene lactone, 6-hydroxy-4,4,7a-trimethyl-5,6,7,7a-tetrahydro-4H-benzofuran- 2-one, was isolated from Ornithogalurn Caudaturn Air, whose structure was confirmed by IR and NMR methods, and its fragmentation pathway was studied by ESI-MS^n. The stereo-structure of the compound was identified by the degree of specific rotation and ^1 H NMR. The experimental results demonstrate that the compound is firstly found in this kind of plant. |
