Convincing evidence has been found for the similarities in physical and chemical characteristics of shilajit and soil humus. Structural similarities of building blocks of the humus core of shilajit and two soil samples have been established by acid hydrolysis of the extracted humus (EHs; free from loosely-bound low Mr organic compounds), followed by comprehensive chromatographic (HPTLC) and spectroscopic (u.v., [1H]NMR, GC, MS) analyses of the degradation products. 13C-isotopic abundance data of the core molecules, as determined from their respective (M + 1) values, in the EI MS, suggest that the origin of these molecules in shilajit, at least in part, predates their biological synthesis (e.g. by plant-microbial interaction). Additional evidence has been found in support of this contention. A memory molecule (1 and its hemiquinone complement, 5a...5b), that exhibited appropriate chemical and biological properties has been encountered in the core of all humus samples.
