Abstract

The results brought back at the end of this work concerned various chemical constituents of P. butyracea materials collected in seven forest galleries in northern of Benin. The phytochemical analysis showed mucilage, coumarins, gallic tannins, flavones, sterols, and saponins, in its leaves. The cyclohexanic fractions realized from petroleum ether extracts and analysed by GC/MS were marked by important rates of 9, 19-cyclolanost-24-en-3β-3-ol (49.3–72.6%), taraxasterol (18.4–30.1%), and friedooleanan-3-one (10.0%). Essential oils extracted by hydrodistillation from P. butyracea and analyzed by GC/MS contained 11 to 38 compounds representing 85.2 to 99.5% of the weight of this volatile extracts essentially rich in sesquiterpene constituents. The essential oils predominant compounds (>10%) identified and recorded independently of the organ studied were β-caryophyllene (14.9–77.9%), aromadendrene (43.5%), α-copaene (18.4–26.6%), α-ylangene (21.1%), germacrene-B (5.1–13.5%), selina-3,7(11)-diene (13.3%), α-humulene (6–13.3%), (2E, 6Z)-α-farnesene (12.6%), seychellene (12.0%), and palmitic acid (10,6%).
