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.

“…Algumas espécies deste gênero são utilizadas na medicina humana, principalmente contra tosse e bronquite (Agra et al, 2007) e doenças de pele, pela presença de furanocumarinas (Cardoso et al, 2002) e compostos do tipo terpenóides têm sido relatados como os responsáveis pelo uso popular destas plantas como antiofídicos (Vilegas et al, 1997).…”

RESUMO:Conhecida como carapiá, a espécie Dorstenia multiformis Miquel, Moraceae, é largamente empregada na medicina popular contra doenças de pele. Neste trabalho determinouse a atividade antioxidante de substâncias isoladas, do extrato etanólico, e frações hexano, clorofórmio e acetato de etila. Todas as amostras testadas apresentaram atividade antioxidante, sendo que a fração clorofórmio foi a que apresentou maior atividade antioxidante.Unitermos: Dorstenia multiformis, fi toquímica, atividade antioxidante, carapiá.ABSTRACT. "Contribution to the phytochemical study of Dorstenia multiformis Miquel (Moraceae) with approach in antioxidant activity". The species Dorstenia multiformis Miquel, Moraceae, known as "carapiá", is largely employed in folk medicine against skin diseases. In this paper the antioxidant activity of isolated substances, from the ethanol extract, and hexane, chloroform and ethyl acetate fractions has been determined. All of the tested samples showed antioxidant activity, and the chloroform fraction was the one that presented the largest antioxidant activity.

As a part of a wider study aimed at determining new molecular biomarkers in soils and sediments that could be specific of distinct vegetation types with respect to unravelling past changes in land use, we analysed the neutral lipid content of soil developed in the catchment of a small lake in central France. The ketone/acetate lipid fraction of soil under pasture or meadow contains a series of pentacyclic triterpenyl acetates of wide structural diversity, most being reported in soil for the first time. The restricted number of potential plant sources of triterpenyl acetates (some produced by a single species) underlines the potential of triterpenyl acetates as new biomarkers to track past vegetation change in palaeoenvironmental studies, when found in natural archives such as soil, sediments or peat.
