This work describes the isolation of p-menthene glycosides 27 and 29 from the aerial parts of Ageratina glabrata. The acid hydrolysis of 27 and 29 yielded to the obtaining of p-menthene derivatives 22-26. Also, the preparation ...

The present the preparation of thymhydroquinone (1) is described by using p-menthene (35), which was isolated from the acid hydrolysis of the methanolic extract of the aerial part of Ageratina glabrata, emplaying oxidative ...
