Mimosa pudica, commonly known as touch-me-not, is used in folklore medicine in arresting bleeding and in skin diseases.
There was no scientific evidence justifying the use of Mimosa pudica, therefore the present study was aimed at evaluation of wound healing activity of the plant.
In the present study the roots of Mimosa pudica were studied for wound healing activity by incorporating the methanolic and the total aqueous extract in simple ointment base B.P. in concentration of 0.5% (w/w), 1% (w/w) and 2% (w/w). Wound healing activity was studied in three types of model in rats viz. excision, incision and estimation of biochemical parameter. In case of the excision wound model wound contraction and period of epithelization was studied while in incision wound model was evaluated by determining tensile strength and hydroxyproline content in the scab.
Treatment of wound with ointment containing 2% (w/w) the methanolic and 2% (w/w) the total aqueous extract exhibited significant (P<0.001) wound healing activity. The methanolic and total aqueous extracts were analyzed for total phenols content equivalent to Gallic acid. The content of total phenols was 11% (w/w) and 17% (w/w) in methanolic and total aqueous extract respectively.
The methanolic extract exhibited good wound healing activity probably due to phenols constituents.
含羞草,俗称“别碰我”,在民间医学中用于止血和治疗皮肤病。
此前并无科学证据支持含羞草的药用价值,因此本研究旨在评估该植物的伤口愈合活性。
在本研究中,将含羞草的根制成甲醇提取物和总水提取物,并按0.5%(w/w)、1%(w/w)和2%(w/w)的浓度加入英国药典规定的简单软膏基质中,以此研究其伤口愈合活性。通过三种大鼠伤口模型来研究伤口愈合活性,即切除伤口模型、切开伤口模型和生化参数评估。在切除伤口模型中,研究伤口收缩和上皮形成的时间;在切开伤口模型中,通过测定痂皮的抗张强度和羟脯氨酸含量进行评估。
用含2%(w/w)甲醇提取物和2%(w/w)总水提取物的软膏处理伤口,显示出显著(P<0.001)的伤口愈合活性。对甲醇提取物和总水提取物分析了相当于没食子酸的总酚含量。甲醇提取物和总水提取物中的总酚含量分别为11%(w/w)和17%(w/w)。
甲醇提取物表现出良好的伤口愈合活性,可能归因于其酚类成分。
