親愛的美安經銷商夥伴:大家好!
電子版「植物療法研究」期刊發表一份最新研究報告,對等滲透劑型溶液的吸收速度做出評估,並將其與製成錠狀劑型加以比較。實驗發現,等滲透劑型溶液在10分鐘內立即減少血漿內的氧自由基,而錠狀劑型經過約1小時才能達到相似效果。在整整四小時內,與錠狀劑型相比,等滲透劑型確實具有更強的抗氧化功效。
結果顯示,就抗氧化功效而論,與相同類黃酮成分的錠狀相比,等滲透劑型溶液的類黃酮成分更容易為人體所利用。這就是說等滲透劑型溶液的抗氧化功效優於錠狀劑型的功效。此項研究成果已於2009年6月發表。
有關詳細研究報告摘要, Department of Biomedical Science, G D'Annunzio University Chieti, Pescara, Italy. The degree of absorption of bioflavonoids, a diverse and complex group of plant derived phytonutrients, has been a frequent debate among scientists. Monomeric flavonoid species are known to be absorbed within 2 h. The kinetics of plasma reactive oxygen species, a reflection of bioactivity, of a commercial blend of flavonoids, OPC-3 was investigated. OPC-3 was selected to compare absorption of an isotonic flavonoid solution vs tablet form with the equivalent amount of fluid. In the case of isotonic OPC-3 the reactive oxygen species of the subject's plasma decreased significantly (p < 0.05), six times greater than OPC-3 tablets by 10 min post-consumption. After 20 min the isotonic formulation was approximately four times more bioavailable and after 40 min twice as bioavailable as the tablet, respectively. At time points 1 h and later, both isotonic and tablet formulations lowered oxidative stress, although the isotonic formulation values remained significantly better throughout the investigation period of 4 h. These findings point to a dramatically accelerated bioavailability of flavonoids delivered in an isotonic formulation. (c) 2009 John Wiley & Sons, Ltd.
