ABSTRACT
Protium heptaphyllum (Aubl.) Marchand (PH) trees are endemic to the tropical region of South America, mostly Brazil. Antibacterial, antinociceptive, anti-inflammatory, anxiolytic, antidepressant and anti-hyperlipidemic/anti-hypercholesterolemic effects were reported for its resinous exudate Protiumheptaphyllum resin (PHR). This work aims to provide a qualitative and quantitative consistent chemical profiling of the major constituents of this resin and two extracts enriched in acid (acidic triterpene concentrated extract, ATCE) and neutral triterpenes (α and ß-amyrin concentrated extract, AMCE). GC-MS/GC-FID was used for volatile terpene fraction, a validated GC-MS method was developed for quantification of neutral α and ß-amyrin and HPLC-APCI HRMS2 was used for acidic triterpenes analysis. The chemical investigation reported 29 molecules, including 14 volatile terpenes, 6 neutral triterpenes and 11 acid triterpenes. The most abundant compounds were α-amyrin (251.28 g kg-1, 123.98 g kg-1 and 556.82 g kg-1 in PHR, ATCE and AMCE, respectively), ß-amyrin (172.66 g kg-1, 95.39 g kg-1 and 385.58 g kg-1 in PHR, ATCE and AMCE, respectively), 3-oxo-tirucalla-7,24-dien-21-oic acid (80.64 g kg-1, 157.10 g kg-1 and 15.31 g kg-1 in PHR, ATCE and AMCE, respectively) and 3α-hydroxy-tirucalla-8,24-dien-21-oic acid (77.71 g kg-1, 130.40 g kg-1 and 11.64 g kg-1 in PHR, ATCE and AMCE, respectively). Results showed specific enrichment of acidic and neutral triterpenoids in the two respective extracts.
