    摘要: 本研究主要探討常食用鄉土蔬菜抗氧化物質含量與其抗氧化活性之研究，鄉土蔬菜共計有紅鳳菜、山芹菜、藤三七、劍葉萵苣、角菜、龍葵、秋葵、九層塔、紫蘇、過溝菜蕨、香椿、紫葉用甘藷、山蘇、枸杞菜、甘蔗筍、綠葉用甘藷、龍鬚菜、皇宮菜、綠金針花、莧菜、水蓮、黃梨瓜、深綠梨瓜、山苦瓜、烏塌菜、紅莧菜、黃金針花、淺綠梨瓜與乾梨瓜等共29種。分析抗氧化物質包括：多酚類、類黃酮、黃酮醇類與花青素類，並以HPLC進行黃酮醇類定量與定性分析。分析抗氧化活性指標包括：清除DPPH自由基能力、Trolox當量的抗氧化能力與氧自由基吸收能力。結果顯示：香椿具有較多多酚類；紫蘇具有較多類黃酮與黃酮醇。香椿具有最佳清除DPPH自由基能力與Trolox當量的抗氧化能力；氧自由基吸收能力則以紫蘇為最佳；在HPLC進行黃酮醇類定性與定量分析，枸杞葉與紫蘇含Quercetin量最高；Myricetin以淺綠梨瓜含量最高；Morin以角菜與紫蘇為最高；Kaempferol則以紅鳳菜及香椿含量最高。綜合之以香椿、紫蘇含有豐富抗氧化物質與抗氧化活性，結果將來可提供鄉土蔬菜抗氧化機能性成分之開發。
    The aim of this study was to evaluated the antioxidant substances and antioxidant activity of Taiwan indigenous vegetables, including Gynura bicolor DC., Sanicula lamelligera Hance, Anredera cordifolia Steenis, Lactuca indica var. idivisa Mak Hara, Artemisia lactiflora Wall., Solanum nigrum, Abelmoschus esculentus Moench., Ocimum bullatum, Perilla ocymoides var. crispa Benth. f. purpurea Makino, Anisogonium esculentum Presl., Toona sinensis M. Roem., Ipomoea batatas (purple leaf), Asplenium antiquum Makino, Lycium chinense Mill., Saccharum officinarum, Ipomoea batatas (green leaf), Potamogeton pectinatus, Basella alba, Hemerocallis fulva (green), Amaranthus mangostanus (green), Nymphoides cristata (Roxb.) O. Kuntze, Sechium edule (Jacq.) Swartz (yellow), Sechium edule (Jacq.) Swartz (dark green), Momordica charantia var. abbreviata Ser., Brassica campestris, Amaranthus mangostanus (red), Hemerocallis fulva (yellow), Sechium edule (Jacq.) Swartz (pale green), Sechium edule (Jacq.) Swartz (dry).
    The antioxidant substances included polyphenol, flavonoids, flavonols and anthocyanidins. The individual of flavonols, such as quercetin, myricetin, morin, kaempferol were also determined. The antioxidant activity was evaluated by DPPH radicals scavenging, TEAC values and oxygen radical absorption capacity (ORAC) values.
    In results, the polyphenol content was rich in Toona sinensis M. Roem.. The flavonoids, flavonols and anthocyanidins contents were rich in Perilla ocymoides var. crispa Benth. f. purpurea Makino. Toona sinensis M. Roem. had the best IC50 of DPPH radicals scavenging value and also had the best TEAC values. Perilla ocymoides var. crispa Benth. f. purpurea Makino had best ORAC values. The quercetin was rich in Lycium chinense Mill. and Perilla ocymoides var. crispa Benth. f. purpurea Makino, while myricetin was rich in Sechium edule (Jacq.) Swartz (pale green). The morin was rich in Artemisia lactiflora Wall. and Perilla ocymoides var. crispa Benth. f. purpurea Makino, while kaempferol was rich in Gynura bicolor DC. and Toona sinensis M. Roem..
    In conclusion, Toona sinensis M. Roem. and Perilla ocymoides var. crispa Benth. f. purpurea Makino had rich antioxidant substances and had best antioxidant activity. The result can provide for the future to development of functional food products from the richest source of antioxidant substances in these indigenous vegetables.
