曾經使用過的學名有Abies marianaPicea brevifoliaPicea nigra。原生於美國北方和加拿大全境,主要生長在沼澤地或厚苔沼(muskegs),枝葉和種子可食。加拿大魁北克每年約有92萬公噸乾重的杉樹皮,因為是木材廠的廢棄物,所以多被燒掉做為能源[1][2]

 

【生理活性】

 

黑雲杉枝葉水蒸餾精油成分有乙酸龍腦酯(bornyl acetate34.2%)、莰烯(camphene16.4%)α-蒎烯(α-pinene12.9%);純露含α-萜品醇(α-terpineol14.8%)、龍腦(borneol13.5%)、乙酸龍腦酯(7.8%)、萜品烯-4-(terpinen-4-ol6.5%)和順3-己烯-1-(cis-3-hexen-1-ol6.5%)[3]。乙酸龍腦酯和莰烯多來自針葉,α-蒎烯來自樹枝和針葉的比例約21[4]

 

樹皮精油主要是α-蒎烯(40.5-40.6%)β-蒎烯(β-pinene25.9-33.9%)β-茴香萜(β-phellandrene3.6-4.8%)3-蒈烯(3-carene3.1-4.1%)和檸烯(limonene3.7-4.0%);純露有α-萜品醇(29.3-33.5%)、萜品烯-4-(5.0-5.8%)、反式松香芹醇(trans-pinocarveol3.7-5.2%)、馬鞭烯酮(verbenone4.9-5.4%)、龍腦(3.9-4.9%)和松香芹酮(pinocarvone4.3-4.6%)[5]

 

民俗療法

 

北美洲利用樹脂使傷口加速癒合,包含皮疹或傷燙傷引起的化膿[6]。浸泡茶可治咳嗽和便秘[7]。約1870年,黑雲杉膠曾被製成糖漿,用以治療咳嗽和支氣管炎。樹皮浸漬液可舒緩胃痛、腎結石或關節炎;針葉浸漬液緩解皮膚乾燥或潰瘍。含內皮的敷料用於抗發炎。[2]

 

抗發炎

 

黑雲杉樹皮的熱水-乙酸乙酯萃取物能抑制TNF-α誘發的細胞發炎反應。乾癬角質細胞在TNF-α存在下[8],產生的發炎因子NOIL-6IL-8fractalkinePGE2以及細胞間黏附因子(ICAM-1)表現會顯著多過正常人類細胞,但萃取物能透過NF-κB路徑有效抑制發炎因子濃度。

 

進一步分析[9],每1 g的黑雲杉樹皮乾重至少含有104 μg的反式白藜蘆醇,而乙酸乙酯萃取物也主要都由多酚類物質所組成,包含5種新木脂素、7種木脂素、反式白藜蘆醇、3種酚酸和4種黃酮類,這些分子或多或少對抗發炎都有所貢獻。

 

抗癌

 

作者選用加拿大邊境29種藥用植物的己烷萃取物,分析抑制急性淋巴性白血病細胞的能力[7],結果半數抑制能力IC50以軟鹿蕊(Cladina mitis)6.63 ± 0.03 μg/mL最有效,其次是黑雲杉針葉的8.65 ± 0.38 μg/mL,以及冷嵩(Artemisia frigida)9.67 ± 1.36 μg/mL。若是酒精或甲醇萃取物則無效。

 

美白、抗老化

 

彈力蛋白分解酶(elastase)和酪胺酸酶是彈力蛋白分解和皮膚生成黑色素所需參與的酵素,抑制其活性有助改善皺紋和美白。黑雲杉樹皮熱水和酒精萃取物具有抑制2者活性的功效[10]。熱水萃取物能抑制彈力蛋白分解酶61.9 ± 9.7%IC504.6 ± 0.3 mg/mL,抑制酪胺酸酶50.8 ± 2.6%;酒精萃取物可抑制彈力蛋白分解酶41.4 ± 1.5%和酪胺酸酶48.3 ± 6.8%。兒茶素抑制彈力蛋白分解酶IC500.114 mg/mL;麴酸和熊果素抑制酪胺酸酶活性分別為95.3± 0.8%86.9 ± 2.6%

 

可能風險

 

大鼠口服黑雲杉樹皮水萃取物的LD50超過2,000 mg/kg,表示沒有急性毒性[1]。小鼠單核巨噬細胞和400 μg/ml的黑雲杉樹皮水萃取物培養48小時,未顯示毒性,但經純化後的高濃度多酚/原花青素組合物在100-200 μg/mL便顯現毒性[11]

 

【芳療功效】

 

鐮刀菌屬(Fusarium spp.)真菌會造成馬鈴薯乾腐,果膠桿菌屬(Pectobacterium spp.)Dickeya spp.細菌是軟腐主因。加拿大黑雲杉樹皮的乙酸乙酯萃取物薰蒸可有效抑制馬鈴薯P. carotovorum、黑腐果膠桿菌(P. atrosepticum)D. dianthicola等軟腐菌,最小抑菌濃度為0.6%;以及真菌尖孢鐮刀菌(F. oxysporum)和接骨木鐮刀菌(F. sambucinum),最小抑菌濃度從1.37 × 10-33.71 × 10-2 %,效果比商品Emesto Silver更佳。其他水、酸鹼萃取物和針葉精油,只有部分效果。

 

經黑雲杉針葉10%精油的薰蒸處理後,存放4周期間,能有效抑制馬鈴薯發芽50%25%精油可抑制99%,濃度若再高則表面會有可見的光毒性反應。混合25%精油和1%乙酸乙酯萃取物表現出協同效應,在犧牲些微抗菌力的同時,也能有效抑制馬鈴薯發芽[12]
