| Abstract: | Three new 2,2-dimethylchroman derivatives named leptin A(I), leptin B(II), and leptin C(III), along with a known compound-isoevodionol (IV), have been isolated from the aerial parts of Evodia lepta (Spreng.) Merr. Based on the spectroscopic analysis and chemical evidence, compounds I,II,III were elucidated as cis-3, 4, 5-trihydroxy-6-acetyl-7-methoxy-2, 2-dimethylchroman, trans-3,4,5-trihydroxy-6-acetyl-7-methoxy-2,2-dimethylchroman and 3,5-dihy-droxy-4-ethoxy-6-acetyl-7-methoxy-2,2-dimethylchroman, respectively. |
