The previous assignment of the type C skeleton of polycyclic polyprenylated acylphloroglucinols (PPAPs) was controversial and proved to be incorrect in this study. The structures of the type C PPAPs (3-6) were revised to corresponding type A structures (3a-6a) via C NMR spectroscopic analysis and a quantum computational chemistry method. Therefore, only types A and B PPAPs are likely present in plants of the family Clusiaceae.
多环多异戊烯基酰基间苯三酚（PPAPs）C型骨架先前的归属存在争议，且在本研究中被证明是错误的。通过碳核磁共振光谱分析和量子计算化学方法，C型PPAPs（3 - 6）的结构被修正为相应的A型结构（3a - 6a）。因此，在藤黄科植物中可能仅存在A型和B型PPAPs。
