valencene and grandiflorenic-acid

Montanoa tomentosa has been used in traditional medicine in Mexico to treat diverse female health disorders; it is particularly useful in inducing childbirth. Microscopic analysis of leaf surfaces of M. tomentosa revealed the presence of glandular trichomes. The chemical profile and distribution of glandular trichomes from different developmental stages of M. tomentosa leaves were investigated. Two diterpenic acids, kaurenoic and grandiflorenic were detected in glandular trichomes through the glandular microsampling technique and GC/MS analysis. In the glandular trichomes of the leaves also up to twenty-six volatile terpenes were identified, where beta-eudesmol and valencene were the most abundant terpenes.
