(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 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 β-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 β-amyrin and HPLC-APCI HRMS 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, 123.98 g kg and 556.82 g kg in PHR, ATCE and AMCE, respectively), β-amyrin (172.66 g kg, 95.39 g kg and 385.58 g kg in PHR, ATCE and AMCE, respectively), 3-oxo-tirucalla-7,24-dien-21-oic acid (80.64 g kg, 157.10 g kg and 15.31 g kg in PHR, ATCE and AMCE, respectively) and 3α-hydroxy-tirucalla-8,24-dien-21-oic acid (77.71 g kg, 130.40 g kg and 11.64 g kg in PHR, ATCE and AMCE, respectively). Results showed specific enrichment of acidic and neutral triterpenoids in the two respective extracts.
(Aubl.) Marchand (PH) 树原产于南美洲的热带地区,主要是巴西。其树脂状渗出物树脂 (PHR) 具有抗菌、镇痛、抗炎、抗焦虑、抗抑郁和抗高血脂/抗高胆固醇作用。本工作旨在对该树脂及其两种富含酸(酸性三萜浓缩提取物,ATCE)和中性三萜(α和β-香树脂醇浓缩提取物,AMCE)的提取物中的主要成分进行定性和定量一致的化学分析。GC-MS/GC-FID 用于挥发性萜烯馏分,建立了验证的 GC-MS 方法用于定量分析中性 α 和 β-香树脂醇,HPLC-APCI HRMS 用于酸性三萜分析。化学研究报告了 29 种分子,包括 14 种挥发性萜烯、6 种中性三萜和 11 种酸性三萜。最丰富的化合物是 α-香树脂醇(PHR、ATCE 和 AMCE 中的 251.28 g kg、172.66 g kg 和 556.82 g kg)、β-香树脂醇(PHR、ATCE 和 AMCE 中的 123.98 g kg、95.39 g kg 和 385.58 g kg)、3-氧代-齐墩果-7,24-二烯-21-酸(PHR、ATCE 和 AMCE 中的 80.64 g kg、157.10 g kg 和 15.31 g kg)和 3α-羟基-齐墩果-8,24-二烯-21-酸(PHR、ATCE 和 AMCE 中的 77.71 g kg、130.40 g kg 和 11.64 g kg)。结果表明,两种提取物中酸性和中性三萜类化合物有特定的富集。
