Zusammenfassung:The invention relates to a process for preparing nutraceutical formulations for oral administration, with hepato-digestive protection effect. According to the invention, the process consists of the following steps: preparing a fine powder extract from a plant-based hydroalcoholic extract in a mass concentration of 20% containing equal parts of dried honeyberries or Siberian blueberries flesh, dried bitter cherries or bird cherries flesh, dried grape pomace of red grapes, possibly barley germs as powder, by ultrasound treatment at the ambient temperature for 15 min, possibly enriched with strains of Lactobacillus probiotics, loading the extract on a selective support, such as hybrid mesoporous silica nanomatrix MCM41, mixing the mixture as fine powder with usual conditioning excipients, homogenizing and drying the mixture in an oven, at 35°C for 24 h, compressing the powder by direct tabletting, to result in nutraceutical formulations as uncoated tablets with sustained release which are non-cytotoxic, having synergistic antioxidant antimicrobial effect, with hepato-digestive protective role. Invenţia se referă la un procedeu de obţinere a unor formulări nutraceutice pentru administrare orală cu acţiune de protecţie hepatodigestivă. Procedeul, conform invenţiei constă în etapele: preparare a unui extract pulbere fină dintr-un extract hidroalcoolic vegetal de concentraţie masică 20% conţinând în părţi egale pulpă de fructe uscate de caprifoi albastru sau afin siberian, pulpă de fructe uscate de cireş amar sau cireş păsăresc, produs uscat tescovină din struguri roşii, eventual, pulbere din germeni de orz, prin metoda ultrasonării la temperatura camerei, timp de 15 min, eventual, îmbogăţite cu amestec de tulpini de probiotice Lactobacillus, încărcarea extractului pe suport selectiv de tip nanomatrice hibridă de silice mezoporoasă MCM41, amestecarea mixturii pulbere fină cu excipienţi de condiţionare uzuali, omogenizarea şi uscarea amestecului în etuvă la 35°C timp de 24 h, comprimarea pulberii prin metoda tabletării directe, rezultând formulări nutraceutice sub formă de comprimate neacoperite cu eliberare prelungită, non-citotoxice, cu acţiune sinergică, antioxidantă şi antimicrobiană, cu rol de protecţie hepatodigestivă.
