Abstract：
:Three undescribed polycyclic polyprenylated acylphloroglucinols (PPAPs) and three tocotrienols derivatives, named as paucinochymol A-F (1-3 and 10-12), together with six known PPAPs, were isolated from the fruits of Garcinia paucinervis. Their structures and absolute configurations were determined by extensive NMR analysis and electronic circular dichroism (ECD) calculation methods. Paucinochymol A (1) is the first compound of this type featuring a ω-isogeranyl with tetrahydrofuran unit at C-1. Paucinochymols D and E (4-5) belong to rare tocotrienol with one glorious macrocyclic and an ortho-quinone moiety, respectively. The antiproliferative and anti-inflammatory activities of all isolates were tested. Four PPAPs exhibited weak inhibitory activities against three human cancer cell lines (HepG2, T98, MCF-7) with IC50 values ranging from 10.0 to 16.0 μM. Paucinochymol D (10) displayed moderate inhibitory effects against nitric oxide (NO) production with the IC50 value of 19.8 μM.
