The present enquiry was intended to analyze the phytochemicals qualitatively and quantitatively from flowers of Spanish cherry tree. Flower powder was extracted using polar and nonpolar solvent by soxhlet apparatus. Percentage yield of crude extracts was determined and further the extracts were subjected to analyze the phytochemicals qualitatively and quantitatively by standard procedure. Qualitative analysis showed the absence of alkaloids while presences of tannins, saponins, terpenoids, steroids, glycosides, flavonoids, phenols. Quantitative estimation of phytochemicals was determined using standard curve. Result revealed that the tannin content was 4.3±0.01 (mgTAE /gm), flavanols content was 0.28±0.05 (mgQE/gm). Saponins content was 3.6±0.7 % and terpenoids content was 1.47±0.37 %. A well conducted studies on phytochemicals revealed that they are vital for humans because they provide protection against a variety of ailments. Therefore, the present study is aimed to analyze phytochemicals qualitatively and quantitatively. Keywords: Phytochemicals, Tannins, Saponins, Flavanols, Terpenoids

The total phenolic and tannin content present in the ethanolic extracts of Murrayakoenigii twigs was estimated in this study. The ethanolic extracts of Murrayakoenigii twigs phenolic and tannin contents were measured using Folin-Ciocalteu’s method. Folin-Ciocalteu’s method. Works on the basis of oxidation and reduction reaction with single electron transfer with gallic acid and tannic acid taken as standards. The study revealed the presence of a significant amount of phenolic and tannin content in the ethanolic extracts of Murrayakoenigii twigs.

Quantitative determination of polysaccharides in <em>Ganoderma lucidum </em>fruit bodies from different sawdust cultivation substrates and their antibacterial activity was done. Thirty six samples were analyzed. Four strains of <em>Ganoderma lucidum </em>(GL01, GL02, GL03 and GL04) were cultivated on the growth substrates of three different sawdust types: birch (Bo), maple (Kl) or alder (Ol) amended with wheat bran in three different concentrations: 10, 20 and 30% (w/w). Even though the richest in polysaccharides was GL01 strain, the highest yields of the polysaccharides were determined in GL04Kl3 sample and was 112.82 mg/g of dry weight. The antibacterial activity of polysaccharides was determined in vitro using micro-dilution broth method. The panel of eight reference bacterial strains was used. All the polysaccharide samples tested showed the broad spectrum and the moderate antibacterial activity. <em>Micrococcus luteus </em>ATCC 10240 strain was the most sensitive with <em>MIC </em>(minimal inhibitory concentration) = 0.63 − 1.25 mg/mL.
