    Abstract: 探討虎杖乙醇萃取物及其成分大黃素與白黎蘆醇抑制EB病毒溶裂循環的效應‧以trypanblue分析細胞存活率,以西方墨點法,免疫螢光法及流式細胞儀分析EB病毒溶裂循環蛋白質表現,以Real-time PCR分析病毒顆粒,以螢光素酶分析病毒溶裂循環基因轉錄。結果顯示虎杖乙醇萃取物對於P3HR1細胞的CC50為67.47μg/ml。虎杖乙醇萃取物、大黃素與白黎蘆醇分別在25μg/ml、9.37μM及55μM時具有抑制EB病毒溶裂蛋白質Rta、Zta及EA-D的表現;也分別降低66.70%,27.68%及54.20%病毒顆粒量。虎杖乙醇萃取物濃度25μg/ml對病毒溶裂循環早期基因BRLF1及BZLF1轉錄抑制能力分別為77.29%及70.53%,大黃素在濃度9.37μM的抑制能力分別為16.93%及31.17%;而白黎蘆醇在濃度6.25μM抑制BRLF1及BZLF1轉錄能力分別為88.11%及92.04%。所以本研究發現虎杖乙醇萃取物與其主要成分大黃素及白黎蘆醇具有抑制EB病毒早期基因的表現,並且影響病毒溶裂蛋白質的表現,進一步抑制病毒的複製而達到抗病毒的效果。
