Abstract
The chemical composition of the essential oils obtained from stems and leaves, fruits and roots of
Scaligeria tripartita oil was analyzed by gas chromatography–mass spectrometry. A total of 38 compounds were identified ranging 89–94% of the oil samples. Geijerene was found as a main compound in the oils of the stems and leaves (37%) and fruits (55%), whereas epoxypseudoisoeugenol angelate (37%) was found as a main compound in the root oil. Oils were subsequently evaluated for their antimalarial, antimicrobial against human pathogenic bacteria or fungi and antifungal activities against plant pathogens. Antifungal activity of
Scaligeria oils was observed against the strawberry anthracnose-causing fungal plant pathogens
Colletotrichum acutatum,
C. fragariae and
C. gloeosporioides using the direct overlay bioautography assay. Chemotaxonomically important pure compounds indicated in the bioautography assay were subsequently evaluated in a 96-well microdilution broth assay. The performance of overpressured layer chromatography (OPLC) and TLC for the analysis of
Scaligeria essential oils was also compared.
