QUALITY CONTROL METHODS OF Acacia catechu EXTRACT BY ATOMIC ABSORPTION SPECTROSCOPIC ANALYSIS

The aim of the present study was to evaluate the heavy metal quality control parameters of Acacia catechu bark extract by atomic absorption spectroscopic (AAS) analysis. Acacia catechu is one of the most commonly used herbs in Ayurveda. The whole parts of Acacia catechu tree including stem, bark, leaves, root, and pods are of significant medicinal value in treating many diseases and disorders. The most important actions of Acacia include antioxidant, hepatoprotective, hypotensive, and also as an anti caries, for gingivitis, etc,. Heavy metals such as lead (Pb) and arsenic (As) and minerals such as selenium (Se), chromium (Cr) and potassium (K) are found abundantly in the soil. They are also essential for plant growth and metabolism as micro and macro nutrients. Hence, uptake of these heavy metals and minerals basically occurs in significant proportions in plants. However, these heavy metals and essential trace elements have a tendency to accumulate in alarming proportions in plants leading to toxicity and adverse effects when consumed. Hence, it is important to determine if the heavy metal and mineral content in Acacia is within permissible limits as indicated by WHO. Based on the results of the study, it can be decided whether Acacia catechu can be prescribed for human consumption or not.
