Glabridin is the main biologically active phytocomponent of Glycyrrhiza glabra L. Although glabridin is one of the most studied flavonoids in licorice, the main literature is devoted to its biological activity, but there is a lack of data on its isolation methods, technology and standardization. In this work, the effect of estrogens on the yield of glycyrrhizic acid and glabridin contained in raw materials was studied and analyzed, when processing licorice root in various ways, and also find the optimal waste from this production for the production of glabridin. As a result of the research, it was found advisable to use production waste (meal) from enterprises using water or 10% ethyl alcohol as a solvent to obtain glycyrrhizic acid and its salts from licorice root when producing glabridin. It has been established that the content of glabridin does not change during drying using methods at 60°C of non-vacuum drying (30 hours), vacuum drying (24 hours) and natural drying (72 hours) as optimal drying conditions for using this production waste (meal) as raw materials. It has been proven in the process of obtaining glabridin from raw materials that ethyl acetate and 96% ethyl alcohol can be used as an estrogen.

Сегодня в мире в результате роста численности населения с каждым днем возрастает проблема обеспечения их качественными кормами, особенно в последнее десятилетие XXI века большой интерес к сельскому хозяйству, наряду с важными для здоровья человека овощными культурами, зерновыми, бобовыми, масличными и другими культурами, являющимися одним из незаменимых и натуральных компонентов их рациона Например, огурцы, помидоры и болгарский перец используются в нашей повседневной жизни для приготовления салатов и многих других блюд. Продукты, выращенные в результате повышения уровня нитратов при выращивании этих продуктов, также вредны для организма. Получение здоровых овощных продуктов без повышения уровня нитратов имеет первостепенное значение.

This paper aims to evaluate the potential of Rhodiola heterodonta L., Ajuga turkestanica L., Rosa canina L. (RC), Petroselinum crispum L., Inula helenium L., Gingko biloba, Curcuma longa L. extracts and their cyclodextrin-encapsulated form against some opportunistic pathogenic microorganisms. It was found that R.heterodonta, I.helenium and G.biloba possess significant antimicrobial activity. When encapsulated with cyclodextrins by different methods antimicrobial activity reduced in case of I.helenium and increased in case of R.heterodonta and G.biloba. Importance of type of cyclodextrin and encapsulation procedure were observed to be specifically involved as well.

The two-stage scheme of gastric ulcer treatment is the most effective: Stage I lasts 7 days. During this period, the patient is prescribed a combination of two antibiotics, usually metronidazole and clarithromycin, as well as a proton pump inhibitor such as lansoprazole. Medicines can be replaced with analogues at the discretion of the attending physician, and the dose is determined individually. The goal of the first stage of treatment is to completely eliminate Helicobacter pylori, and in 95% of cases this task can be overcome; Stage II lasts 14 days and is required only if Helicobacter pylori is found in the stomach after the first stage. A tandem of metronidazole + tetracycline antibiotics is used against bacteria, and the therapy is supplemented with one of the bismuth drugs, as well as PPIs (omeprazole, rabeprazole) and histamine receptor blockers (ranitidine, famotidine).

. Ushbu tadqiqot kadmiy (Cd) bilan ifloslangan tuproqlarni qayta tiklashda uchta bakteriya shtammlarining (Enterobacter ludwiigi, Bacillus simplex, Bacillus licheniformis) alohida va assosiasiyadagi sinergetik ta'sirini baholashga qaratilgan. Sinov o`simligi sifatida bug`doydan foydalanilgan. Enterobacter ludwiigi A11, Bacillus licheniformis A10 va Bacillus simplex A8 bakteriyalarining kombinatsiyalari bilan ishlov berilgan bug`doy urug`lari Cd ning 3 xil konsentratsiyasini (2.4, 4.1, 8.2 mg/kg) o'zida tutgan tuproqlarga ekildi va 30 kun davomida o'simlikning o'sishi va rivojlanishi kuzatildi. O'tkazilgan tadqiqotlar yakunida o'simlik balandligi, poya va ildiz biomassasi, xlorofill miqdori aniqlandi. Bakteriyalarning assosiasiyasi qo'llanilganda, yagona shtamm qo`llanilgandagi natijaga nisbatan o'simliklarning o'sish parametrlari sezilarli darajada rag'batlashtirilgani aniqlandi. Natijalar shuni ko'rsatdiki, tekshirilgan bakteriyalar Cd bilan ifloslangan tuproqlarning bioremediatsiyasini ta`minlashda va o`simlik o'sishini kuchaytirishda sinergetik potensialga egadir.
