Abstract:

The aim of this study was to identify and to assay some therapeutic active principles, both in the foliar buds of hazelnut, Corylus avellana L., and in the hydroglyceroalcoholic extracts, successfully used in gemmotherapy. The microelements have been analyzed using atomic absorption spectrometry, carotenoids and total polyphenols using spectrophotometry, specific polyphenols using HPLC. There were identified free amino acids, growing hormones and free triterpenic acids using TLC, total nitrogen using Kejldhal method, and haemolytic saponines on the base of haemolytic index, according to Romanian Pharmacopeia, Xth edition. The following results were found: high concentration of iron (108 mg/kg) and zinc (0.733 mg/kg); total chlorophyll 28 mg/100 g; total carotenoids 6.40 mg/100 g; total polyphenols 548 mg/100g, total nitrogen 2.28%. We identified free amino acids (arginine, alanine, phenylalanine, proline) and also vegetal growing hormones (auxin, cytokinine and gibberellin). The concentration of haemolytic saponines was around 0.2%. This study demonstrated that the foliar buds of hazelnut have a complex chemical composition, which explains their increased phytotherapeutic potential
