Abstract

Modern extraction and planar chromatographic instrumentation were employed for the fingerprint profiling of carbohydrates from an important and popular medicinal mushroom commonly known as Lingzhi. For the first time, the feasibility of employing the high-performance thin-layer chromatography (HPTLC) peak profiles (fingerprints) of carbohydrates for the screening of various Lingzhi species/products was demonstrated. An analytical procedure was developed such that upon acid hydrolysis of the polysaccharides extracted from various Lingzhi samples, fingerprint profiles that reveal the relative amounts of the degradation products, such as mono- and oligosaccharides, can be obtained using HPTLC plates (Si 50000) for separation and 4-aminobenzoic acid as the post-chromatographic derivatization reagent for detection. Also, using automated multiple development (AMD), the acid hydrolyzates from Lingzhi, consisting of simple and more complex sugars, can be separated simultaneously with high degree of automation. An important finding was that unique fingerprint patterns were observed in the monosaccharide profiles between two highly valued Lingzhi species, Ganoderma applanatum and Ganoderma lucidum, under total or partial acid hydrolysis conditions. Additionally, the HPTLC fingerprint profiles of carbohydrates were obtained from the extracts of the spores and fruiting bodies of Lingzhi and compared.
