    Abstract: 糖尿病(Diabetes mellitus)腎病變是造成末期腎臟病,單一最
    大的原因,糖尿病為我國每年洗腎新增病患的第一主因。如何預防或
    延緩糖尿病腎病變造尿毒洗腎,則是國人保健非常重要的研究工作。
    高血糖糖造成腎病變的分子機制,目前仍不清楚,但蛋白質糖基化作
    用以及在糖基過程中產生的氧化傷害交互作用,被認為是糖尿病多種
    合併症重要的原因。因此,同時具有抗蛋白質糖基化活及抗氧化活性
    的物質,應具有防治糖尿病合併症的潛力。本研究的基本目的即是從
    安全性高的中藥,利用清除自由基能力及抑制熱誘導葡萄糖造成牛血
    清白蛋白糖基化的指標,篩選具有抗蛋白質糖基化活性及抗氧化活性
    之樣品,再進一步了可能的作用機制及有效成分。結果發現在22 種
    篩選的中藥,同時具有強力抗蛋白質糖基化及自由基清除活性的有
    11 種,包括生地黃、川芎、茵陳蒿、白芷、黃芩、牡丹皮、女貞子、
    菊花、決明子、佩蘭及甘草;單純抗蛋白質糖基化的有4 種,包括北
    耆、黨蔘、澤瀉及芡實;五加皮則是唯一具有高自由基清除活性但不
    具抗抗蛋白質糖基化的中藥。分析中藥萃取物中總酚(phenolics)含
    量、總皂素(saponins)含量及總多糖(polysaccharides)含量,發現
    中藥萃取物之總酚含量與其自由基清除活性相關性較高,而總皂素含
    量則與抗蛋白質糖化糖活性相關性較高。本研究數據提出中藥抗蛋白
    質糖基化活性至少有部份是來自其抗氧化活性,而且與所含的總酚含
    量有關,另外中藥中所含的總皂素組成則更具抗蛋白質糖化糖活性的
    專一性。因此在對抗糖尿引發的合併症上,選擇同時具有抗氧化及抗
    蛋白質糖化糖活性的中藥,如生地黃,將優於只具有單純抗蛋白質糖
    化或抗氧化活性的藥物,如黨蔘及北耆等中藥。
    Advanced glycation end products and oxidative stress have been implicated in the
    pathogenesis of diabetic complications. Both are known to interact with each other.
    Therefore, exploring natural compounds that possess both antioxidant and
    antiglycation activities might have great therapeutic potential for treating diabetic
    complications. The main purpose of this study was to evaluate the antiglycation and
    antioxidant properties of aqueous extracts from 22 traditional Chinese herbs (TCHs).
    The polysaccharide, polyphenol, and saponin contents of these TCH extracts were
    also determined. Our results showed that eleven (50%) TCHs possessed high
    antioxidant and high antiglycation activity, four TCHs possessed high antiglycation
    and low antioxidant activity, and only one TCH possessed low antiglycation and high
    antioxidant activity. There was a close correlation between the antioxidant activity of
    most extracts and their polyphenol contents. In addition, antiglycation activity showed
    a weaker correlation with saponin content. These results suggest that the
    antiglycation activities of most extracts can be explained, at least in part, by their
    combined antioxidant and antiglycation properties.
