Neste trabalho é descrita a identificação de alguns constituintes químicos minoritários da "espinheira santa" (Maytenus ilicifolia e Maytenus aquifolium, Celastraceae), planta medicinal amplamente utilizada no Brasil. Através do acoplamento entre cromatografia gasosa de alta resolução e espectrometria de massas (HRGC-MS), foi possível identificar principalmente triterpenóides e esteróides presentes na "espinheira santa", vários dos quais relatados pela primeira vez em ambas as espécies de Maytenus.This work describes the identification of some of the minor chemical constituents of "espinheira santa" (Maytenus ilicifolia and Maytenus aquifolium, Celastraceae), a medicinal plant widely utilized in Brazil. By using high resolution gas chromatography coupled to mass spectrometry (HRGC-MS), it was possible to identify mainly triterpenoids and steroids in "espinheira santa", most of them reported for the first time in both Maytenus species.

Maytenus aqiiifoliurn Mart., popularly known as Espinheira santa, is a native Brazilian tree from which the leaves are extensively used to prepare antiulcerogenic infusions. To determine the effect of fertilization on morphologic characteristics and secondary metabolites, 2 year old plants were transplanted to a prefertilized field and submitted to treatment with organic and inorganic fertilizers. Fields pretreated with fertilizer significantly increased plant height, stem diameter, and the number of leaves and branches, but the levels of triterpenes and total phenols were not affected [Article copies ovailoble from The Haworth Documenl Delivery Service: 1-800- 342-9678.]
