RESUMO

Objective To establish a method for determination and optimize the extraction process of the content of plantamajoside in plantain.Methods Plantamajoside content was determined by HPLC.The effects of ethanol concentration, ethanol amount and extraction time on the extraction of plantamajoside from plantain were studied by orthogonal design.Results The calibration curve was linear (r=0.999 6) over the range of 12.52-125.10μg/ml.The average recovery was 98.57% (RSD=1.45%).The optimum extraction process was as follows:60%ethanol, 10times volumes, extracted 2times, 1heach time.Conclusion The established method was simple, accurate and reproducible for determination of the content of plantamajoside in plantain.The optimal extraction process was stable and feasible.

RESUMO

Impaired wound healing in diabetes is a significant clinical problem which is thought to be associated with neuropathy and angiopathy previously . The present study indicates that accumulation of glucose and glycometabolic products in skin tissue, as the result of glycometabolic disorders, which contributes to cutaneous environmental alterations in diabetes mellitus, and subsequently induces the abnormal cell behaviors, cytokine alteration and matrix modification. Thus, diabetic neuropathy and angiopathy might be regarded as the pathological outcome of cutaneous environmental alterations. In conclusion, glycometabolism disorders could be described as one of the initial events for the alteration involving in the underlying cutaneous disorder which impair healing process. The related research focuses on the initial event of controlling disorders in wound healing and therefore contribute to providing the strategy of treatment as based on these approaches.
