Exploring the geographical variability of Asphaltum punjabianum (Shilajit) from India in elements and phytochemicals variations using GC–MS/MS, LC, ICP OES, and in-silico studies
Abstract
Shilajit is an ancient herbal medicine from India with many uses. It is a viscous material prominently present in the Himalayan and Hindukush rocks of the Indian region. The formation due to plant decompostion with time. Herbs assosciated to the stones reveals about composition of Shilajit. Primary objective is to create GCMS/MS and LC-analysis techniques for separating the phytochemicals and complete profiling of volatile and non-volatile metabolites found in Shilajit. Accordingly, an attempt was undertaken to develop a method for standardisation and, subsequently, certification inorganic content and purity of shilajit in various indian regions S-01, S-02, S-03, S-04, and S-05. Thus, an effort was made to create a fundamental technique for standardization and, consequently, authentication of shilajit that was acquired from various geographical locations.Trace metal concentrations were measured using ICP OES in mg Kg−1 for each sample. These elements included As, Pb, Cd, Ag, Al, B, Ba, Cr, Cu, Fe, Mn, Ni, Sb, Se, Zn, P, Ca, K, Mg, and Na. ICP OES analysis observed the significant concentration of Ca and K, in S-01 (102631 and 26779), S-02 (13529.25 and 36866.35), S-03 (8170.84 and 37989.10), S-04 (9616.37 and 18843.77), and S-05 (4992.10 and 2120.64), appropriately. By measuring the DPPH radical scavenging activity were assessed for their antioxidant activities of the S-01, S-02, S-03, S-04, and S-05 samples: 12.316 ± 0.561 %, 13.144 ± 2.884 %, 15.105 ± 1.421 %, 19.683 ± 2.013 %, and 0.0724 ± 1.045 %, respectively. Concurrently, TPC studies on Shilajit found between 10 and 150 mg g−1 wt Similarly, shilajit’s TFC was analysed with geographically. TFC were found in mg QCE/g of wt of S-01 12.56, S-02 5.56, S-03.48, S-04 49.23, and S-05 5809 each respectively. The phytochemicals protocatechuic acid and hippuric were tested for in silico anti-inflammatory and antihyperglycemic activity of acid, which need to be explored in-vivo applications.
