Streszczenie:

The genus Hypericum comprises a large number of species. The flower, leaf, stem, and root of the Hypericum species are widely used in traditional medicine in different cultures. Many Hypericum species have been well investigated phytochemically and pharmacologically. However, only a few reports are available on the H. cordifolium native to Nepal. The present study aims to evaluate the phytochemical composition of different extracts, qualitative analysis of methanol extract of the flower and leaf using thin-layer chromatography (TLC), and the antioxidant properties of components by the TLC-DPPH

In pharmacy, eucalyptus leaves are used for various pharmacological activities because they contain phenolic compounds. This study aims to detect phytochemical compounds and test the antioxidant activity of Eucalyptus pellita leaf extract. The dry powder of E. pellita leaves (1900 g) was macerated first with methanol solvent. The concentrated methanol extract was then subjected to partition extraction with n - hexane solvent. The methanol layer was concentrated and then partitioned with ethyl acetate solvent. Methanol extract was obtained as much as 176.75 g (9,30%), n-hexane extract 13.77 g (
