The chloroform extract of bark of the tropical tree Qualea parviflora (Vochysiaceae) was fractionated by column chromatography on silica gel, yielding triterpenes (lupeol, lupenone, betulin, epi-betulinic acid and friedelin) ...

Sterol and Triterpenes from Qualea species: Bioactivity on Mycobacterium tuberculosis The chloroform extract of bark of the tropical tree Qualea parviflora (Vochysiaceae) was fractionated by column chromatography on silica ...

Species of the genus Qualea are used by the Brazilian people as a natural anti-inflammatory. Based on this evidence, we evaluated the effects of terpene fractions beta F and TF (rich in beta-sitosterol and terpenoids, ...
