An extract of the Rhodiola semenovii Boriss plant was taken to determine toxicity. Phytochemical studies were carried out on the composition of biologically active compounds for medicinal purposes. Based on the statistical data on the chemical composition, substances, such as flavonoids, coumarins, phenolic acids, and polysaccharides, were identified in the root extract of the Rh. semenovii plant. To study the chronic and acute toxicity of the extract, preclinical tests were on outbred laboratory rats. After completion of the experiment of acute and chronic toxicity, animals were slaughtered and peripheral blood samples were obtained for hematological and biochemical blood analysis. In addition, macroscopic studies of laboratory animals were performed. There were morphologicalstructural changes heart, kidneys, liver, heart, and pancreas. An external examination at the autopsy revealed no changes in the vital organs, as well as the digestive, respiratory, excretory systems. According to the studies carried out, Rh. semenovii does not have general toxic extracts. Keywords: toxicity, pharmacology, Rhodiola semenovii, extract, phytochemistry, acute toxicity, chronic toxicity, hematology. Introduction Currently, researchers, developing priority issues of modern pharmacological science in terms of researching new medicines of natural compounds of various chemical structures and biological action pay great attention to the problem of drug toxicology and the safety of drug use in clinical practice [1]. In accordance with modern concepts, the assessment of the safety of a medicinal herbal preparation (MHP) should take into account all potential risk factors specific to this group of medicinal products. Modern MHP is fundamentally different in terms of the safety of its composition [2]. For successful introduction of new drugs into clinical practice for treatment it is nесеssаrу tо соnduсt а prесliniсаl еvаluаtiоn оf thе drug bаsеd оn intеrnаtiоnаl stаndаrds tо implеmеnt аnd ассеlеrаtе оngоing rеsеаrсh [3–5].

The study of acute, chronic toxicity of the extract was conducted on white mongrel laboratory rats. Animals (males) were kept in cages in groups of 10 individuals of group 3. Sawdust was used as a litter. The air temperature in the vivarium premises was maintained in the range of 18-20 °C at a relative humidity of 60– 70 %. Animals were kept under standard conditions on the vivarium diet. To assess the chronic toxicity of the extract Rh. semenovii, the animals were administered the extract orally for 21 days. To analyze the different significance between samples, Student’s T-criterium at p<0 was used. 05 (Statistica 12, StatSoft Inc., Tulsa, USA). The fluorimeter data was processed and graphed using MS Excel capabilities. Atypical values based on the T-criterion were excluded from the data, a standard sample average error was calculated.

Шокан Rhodiolа semenovi Boriss өсімдігінің жалпы және спецификалық уыттылығын анықтау Фармакологиялық заттардың интоксикациялық құбылыстарын кәсіптік деңгейде болдырмау мақсатында қолданылатын жедел және созылмалы уыттылықты зерттеу дәрілік шөптердің құрамындағы биологиялық белсенді заттардың қалыптасуы жайында ауқымды мәлімет бере алады. Уыттылығын анықтау үшін Rhodiola semenovii Boriss өсімдігінің сығындысы алынды. Дәрілік мақсаттағы биологиялық белсенді қосылыстардың құрамына фитохимиялық зерттеулер жүргізілді. Химиялық құрамы бойынша статистикалық мәліметтерге сәйкес, Rh. semenovii өсімдігінің тамыр сығындысында флавоноидтар, кумариндер, фенол қышқылдары, полисахаридтер сияқты заттар анықталды. Жедел және созылмалы уыттылықты анықтауға арналған материал Rh. semenovii өсімдіктерінің сулы сығындысы болды. Сығындының жедел және созылмалы уыттылығын зерттеу үшін ақ тұқымсыз зертханалық егеуқұйрықтарда клиникаға дейінгі зерттеулер жүргізілді. Жануарлармен бірқатар эксперименттер жүргізілді және сығындының мөлшеріне байланысты гематологиялық көрсеткіштер анықталды. Жедел және созылмалы уыттылық эксперименті аяқталғаннан кейін жануарларды сою жүргізіліп, гематологиялық және биохимиялық қан анализін жүргізу үшін перифериялық қан үлгілері алынды. Сонымен қатар, зертханалық жануарларды сойып, жүрек, бүйрек, бауыр, жүрек, ұйқы безі құрылымындағы макроморфологиялық өзгерістердің болуы зерттелді. Сойғаннан кейін сыртқы тексеру кезінде өмірлік маңызды органдардың, сондай-ақ ас қорыту, тыныс алу, шығару жүйелерінің өзгерістері анықталған жоқ. Клиникаға дейінгі сынақ нәтижелеріне сәйкес, Rh. semenovii жедел және созылмалы уыттылық тәжірибелеріне, GNI сынақтарына, органдардың патоморфологиялық зерттеулеріне, қанның гематологиялық және биохимиялық көрсеткіштеріне сәйкес жалпы уытты қасиеттерге ие емес.

Изучение хронической и острой токсичности терапевтических веществ при внешней оценке признаков интоксикации позволило получить важную информацию о терапевтических свойствах будущего препарата. Для определения токсичности был взят экстракт растения Rhodiola semenovii Вoriss. Были проведены фитохимические исследования по определению состава биологически активных веществ, для дальнейшего использования в терапевтических целях. Согласно имеющимся данным, по химическому составу в экстракте корня растения Rh.semenovii В. были идентифицированы такие вещества, как флавоноиды, кумарины, фенолокислоты, полисахариды. Материалом по определению острой и хронической токсичности служил водный экстракт растения R. semenovii. Для изучения острой и хронической токсичности экстракта предклинические испытания проводились на белых беспородных лабораторных крысах. Проведен ряд экспериментов с животными и определены гематологические показатели в зависимости от дозировки экстракта. После завершения эксперимента острой и хронической токсичности проводили забой животных и получали образцы периферической крови для проведения гематологического и биохимического анализа крови. Кроме того, проводилось вскрытие лабораторных животных и оценивание наличия макроморфологических изменений структуры сердца, почек, печени, сердца, поджелудочной железы. При внешнем осмотре на вскрытии не было выявлено изменений со стороны жизненно важных органов, а также пищеварительной, дыхательной, выделительной систем.
