中文摘要 | 香茹草 (Glossogynetenuifolia (Labill) Cass.),為澎湖縣特有之藥用植物,其有保健醫療功效。不同季節的風乾香茄草有著不同的水分含量,其中以三月的較濕 (10.76%),而以九月的較乾 (7.86%)。一般而言,風乾香茹草含高量的醣類 (碳水化合物)、粗纖維和灰份。本研究利用安氏試驗法 (Ames test) 以鼠傷寒沙門桿菌 (Salmonella typhimurium ) TA98和TA100 為測試菌株,分別以4-硝基喹啉 N-氧化物 (NQNO) 及苯并 [a] 哌 (B[a]p) 之致突變劑,以熱水萃取物為試驗材料,進行其毒性、致突變性及抗致突變性試驗。香茹草熱水萃取物在0.05-2.5 mg/plate 濃度範圍內,對TA98及TA100菌株並未有毒性及致突變性。香茹草熱水萃取物在0.1-5mg/plate時,在NQNO對TA98和TA100菌株致突變性之抑制率分別在 42.86-9.82%和4.34-20.43%之間。香茹草熱水萃取物在5mg/plate時,在B[a]p對TA98和TA100 菌株致突變性之抑制率分別為59.21和27.39%。此結果已足以說明香茹草在飲用上是安全的且其抗致突變之效果。 |
英文摘要 | Glossogyne tenuifolia (Labill) Cass., a special medicinal plant in protection cultivars of Penghu Country, possesses several therapeutic effects. Air-dried G tenuifolia from different seasons contained various amounts of water, in which that from March was moist (10.76%) but that from September was dry (7.86%).Generally, air-dried G tenuifolia were high in carbohydrate, crude fiber and crude ash contents. The research reported herein was to study toxicity, mutagenic and antimutagenic properties of its hot water extract on Salmonella typhimurium TA98 and TA100 using Ames test. The mutagens were 4-nitro-quinoline N-oxide (NQNO)and Benzo [a] pyrene (B[a]p). At 0.05-2.5 mg/plate, hot water extract was not toxic and mutagenic toward TA98 and TA100 strains. At 0.1-5 mg/plate, the inhibitions of mutagenicity of TA98 and TA100 strains induced by NQNO were 42.86-57.14% and 4.34-20.43%, respectively. At 5 mg/plate, the inhibitions of mutagenicity of TA98 and TA100 strains induced by B[a] p were 59.21 and 27.39%, respectively. Based on the results, G tenuifolia is safe for drinking. |
