Determination of Lead in Eleuthero Root Extract by Atomic Absorption Spectrophotometry (AAS)

Eleuthero root extract (also known as Siberian ginseng) is an herbal supplement derived from the root of <i>Eleutherococcus senticosus</i>, a shrub native to north eastern China, Japan, Russia, particularly Siberia. Eleuthero has been used for over 2,000 years in traditional medicine, particularly in Chinese and Russian healing systems. American and Asian ginseng vary in their concentration of active compounds and effects on the body. Ginseng is an herb rich in antioxidants. It may offer benefits for brain health, immune function, blood sugar management, and more. However, more research is necessary. In this present study, explores the application of various analytical techniques for the quantification of lead (Pb) in eleuthero root extract samples. We measured the concentration of eleuthero root extract by using AAS, atomic absorption spectrophotometry. A pretreatment method of the samples, digested the analyte with a mixed acid solution. The AAS method was successfully used for the determination of lead in eleuthero root extract sample. Spectrophotometric determination of lead in eleuthero root extract sample was found to be adequately sensitive in terms of linearity, repeatability, and accuracy. The correlation coefficient (R<sup>2</sup>) was found to be 0.99866, average percent recovery was 97.1%, spiked sample, and 98.6% for the duplicate; and average sample result have been found 1.27 mg/Kg. The results were within the specification of not more than 10 mg/Kg. maximum.
