Abstract
目前對於荔枝的研究大多都集中於果肉、果殼及籽,針對樹葉的研究較少,樹枝的部分目前尚未有文獻探討其成分及藥理作用。荔枝在採收的過程同時也會增加農業廢棄物的產生,因此藉由再利用荔枝的樹枝及樹葉,探討兩種荔枝副產品於雄性禿(AGA)中的促生髮作用。於本次的研究中測定了其化學成分及活性成分,並使用人類毛囊乳禿細胞(HFDPC)以及動物實驗,給予二氫睪固酮(DHT)誘導為AGA模型,探討荔枝樹枝(LCT)、荔枝葉(LCL)是否有抑制DHT的作用以達到促進毛髮生長的作用。於本次的研究結果顯示,荔枝樹枝丙酮萃(LCTA)具有較佳的抗氧化能力,但於細胞實驗中,反而是荔枝樹枝水萃(LCTW)和荔枝樹枝酒萃(LCTE)對於毛囊細胞具有恢復DHT造成的損傷。另外在基因表達中也有增加WNT10b、降低雄激素受體(AR)、DKK1的表現。於動物實驗中也可發現,經由DHT造成的毛囊萎縮,同時給予LCTW和LCTE後便可恢復毛囊的生長,於基因表現中,LCTW隨著劑量的增加而促進WNT10b、β-catenin、Lef1、VEGF的表現,也降低了DKK1、IL-6及AR的表現。LCTE則是在低劑量時表達效果最佳。於Western Blot結果中,LCTW對於AR有較好的抑制作用,LCTE則是隨著劑量的上升而促進WNT/β-catenin這條路徑。在5α-reductase 活性試驗中LCTW及LCTE對於5α-reductase並無抑制作用。最後使用HPLC檢測LCTW和LCTE,發現成分大多相似,但LCTE的含量較多。因此綜合本次的研究結果,LCTW和LCTE均可對DHT造成的傷害進行保護作用,未來可著重研究LCT於雄性禿的治療,並同時減少農業廢棄物的積累。
