Abstract
巒大蕨Pteridium revolutum (BI.) Nakai全草鮮品80%含水甲醇萃取物,經由各種層析管柱及不同溶媒系統層析後,共分離出二十一個化合物,其化學結構根據核磁共振光譜及物理數據分析後,共分為四大類:包括四個酚性化合物:Tyrosol (1)、(S)-4-(2-Hydroxypropyl)phenol (2)、(+)-Betuligenol (3)、p-Cresol (4);四個木脂素類化合物:(+)-Balanophonin (5)、(+)-Pinoresinol (6)、(+)-(7S,7΄S,8S,8΄S)-2-(4-hydroxyphenyl)-6- (3-methoxy-4-hydroxyphenyl)-3,7-dioxabicyclo[3.3.0]octane) (7)、(-)-Lariciresinol (8);九個倍半萜類化合物:(2S,3S)-Pterosin C (9)、(2R,3S)-Pterosin C (10)、(2S)-Pterosin A (11)、(3R)-Pterosin D (12)、(2R)-Pterosin N (13)、(2R,3R)-Pterosin L (14)、(2R)-Pterosin G (15)、(3R)-Pterosin X (16)、2-Hydroxypterosin C (17);四個單萜類化合物:1,2-dihydroxy-3,4-dehydromenthone (18)、(-)-(3R)-8-Hydroxylinalool (19)、(3S,6S)-2,2,6-trimethyl-6-vinyltetrahydro-2H-pyran-3-ol (20)、(3S,6R)-2,2,6-trimethyl-6-vinyltetrahydro-2H-pyran-3-ol (21)。
此外,生物活性檢測方面,由巒大蕨分離出之21個化合物進行對鼠肌纖維母細胞 (Mouse myoblast cells;C2C12 cells) 葡萄糖攝取之評估,在濃度1 μM下其結果發現,化合物7 (120.46 %)、8 (131.38 %)、9 (128.20 %)、11 (116.73 %)、12 (109.69 %)、13 (116.27 %)、17 (145.18 %) 及18 (121.09 %) 具有促進葡萄糖攝取之活性,其中以化合物17之活性最佳。
