    Opis:
    Lentinula edodes (Berk.) Pegler (shiitake) is a species with medicinal properties that is used primarily in traditional medicine, but also in conventional oncology treatment. The first records of Lentinula edodes cultivation reach back to China under the Song dynast (960-1127). The Japanese adopted the Chinese technique of shiitake cultivation, thus becoming its main producer. Currently, shiitake is used in the treatment of lifestyle diseases. Polysaccharides contained in this species strengthen the immune system, eliminate side effects of chemo and radiotherapy and have strong antitumor, antiviral and antibacterial properties. The year 1972 saw a discovery of substances with anti-atherosclerotic effects, with the most important being eritadenine (2 (R), 3 (R)-dihydroxy-4 – (9-adanyl) butyric acid) and statin – lovastatin. L. edodes is of interest to researchers due to its content of therapeutic compounds. These substances have antitumor, antifungal, antibacterial, anti-inflammatory, hypocholesterolemic, antihypertensive, hypoglycaemic and antioxidant effects.

    Opis:
    Bacopa monnieri (Scrophulariaceae) is a well-known plant and has been used by humans for several thousand years. In traditional Hindu medicine, it is one of the most important medicinal plants. The aim of the work was to determine the content of Fe, Mg, and Zn and selected organic compounds before and after extraction into the artificial digestive juices obtained from preparations containing B. monnieri. Commercial preparations in the form of tablets and capsules and B. monnieri shoot cultures were used in the experiment. The metal content in the considered mineralized samples was analyzed by atomic absorption spectrometry and organic compounds by RP-HPLC method. The maximum measured content of the metals released into the digestive juices was as follows: Fe – 32.85; Mg – 367.51; and Zn – 16.41 mg/100 g of the preparation. The existing research shows that metals are best released into the artificial digestive juices from the B. monnieri shoot cultures, and least efficiently from the commercial preparations available in the form of tablets. The phenolic compounds analyzed in the methanol extracts and the extracts of the artificial digestive juices were as follows: protocatechuic acid, p-hydroxybenzoic acid, neochlorogenic acid, chlorogenic acid, isochlorogenic acid, caffeic acid, ferulic acid, cynaroside, trifolin, and luteolin. Bacoside A was only determined in the extracts from the B. monnieri shoot cultures. The experimental results revealed that B. monnieri distributed in the form of tablets did not break down in the artificial digestive juices during the considered time intervals.

    Opis:
    Arthrospira platensis (Spirulina platensis) is a well-known microalga and has been utilized as a medicinal agent and foodstuff by humans since at least 16th century. The aim of this study was to determine zinc content as well as determine phenolic and indole compounds from commercial preparations containing Arthrospira platensis (lyophilizate, tablets, and capsules) before and after extraction with methanol and incubation with artificial digestive juices. The secondary aim of this study was to evaluate the quality of these preparations. The samples were incubated in artificial stomach juice and in intestinal juice. The samples were mineralized and their zinc(II) ions content was estimated using flame absorption atomic spectroscopy (F-AAS). The maximum zinc(II) ions content released into the digestive juices was found to be up to 1.6 mg 100 g-1 of the preparation. Phenolic compounds identified in the examined extracts are as follows: gallic acid; protocatechuic acid; 3,4-dihydroxyphenylacetic acid; p-hydroxybenzoic acid; syringe acid; cinnamic acid; and quercetin. Furthermore, indole compounds identified were 5-hydroxy-L-tryptophan, 5-methyl-L-tryptophan, L-tryptophan, tryptamine, and 5-methyltryptamine. Consequently, it was also found that the distributed Arthrospira platensis in the form of tablets does not disintegrate in the artificial digestive juices. Among the examined preparations, only hard capsules met the requirements of the European Pharmacopeia 8th ed.
