Eight new cembrane-type diterpenoids, boscartins AH-AK (1-8), along with two known ones (9-10), were isolated from the gum resin of . Compounds 1-3 were characteristic of high oxidation assignable to three epoxy groups, while compounds 4-8 were characteristic of two epoxy groups. Spectroscopic examination was used to elucidate their structures. All isolates were evaluated for antiproliferative activity against HCT-116 human colon cancer cells, anti-inflammatory activity against nitric oxide (NO) production, and hepatoprotective activity . All of them showed weak antiproliferative activity (IC > 100 μM), 8 exhibited potent inhibitory effects on NO production (IC of 14.8 μM), with the others showing weak anti-inflammatory activity (IC > 30 μM), and 1 exhibited more potent hepatoprotective activity than the positive control, bicyclol, at 10 μM against the damage induced by paracetamol in HepG2 cells.
从……的树胶脂中分离出8种新的cembrane型二萜类化合物，即波卡廷AH - AK（1 - 8），以及两种已知化合物（9 - 10）。化合物1 - 3具有三个环氧基导致的高氧化特征，而化合物4 - 8具有两个环氧基的特征。通过光谱分析来阐明它们的结构。对所有分离物进行了针对HCT - 116人结肠癌细胞的抗增殖活性、针对一氧化氮（NO）产生的抗炎活性以及肝脏保护活性评估。它们均表现出较弱的抗增殖活性（IC>100μM），8对NO产生具有强效抑制作用（IC为14.8μM），其他化合物表现出较弱的抗炎活性（IC>30μM），并且在10μM时，1对乙酰氨基酚诱导的HepG2细胞损伤表现出比阳性对照双环醇更强的肝脏保护活性。
