Introduction:
Rhodiola rosea L. (R.rosea) is a popular plant in traditional medicine of the Nordic countries, Eastern
Europe, and Asia. R.rosea plants are successfully cultivated in Mongolia. The Botanical Garden of
Medicinal Plants under the “Monos” Group started to cultivate R. rosea since May 2015.
Objective:
The aim of this research was to study the salidroside contents of R.rosea collected from Zavkhan
and Khuvsgul province, Mongolia, and cultivated in the Botanical Garden of Medicinal Plants, Drug
research Institute, Monos group.
Material and Methods:
The underground parts of wild roseroot plants were collected from April to May 2020 from Jargalant
soum, Khuvsgul province, and Nomrog soum, Zavkhan province, 3-years and 4-years-old cultivated
R.rosea gathered from the Botanical Garden of Medicinal Plants in April 2020. For comparison,
4-year-old Rhodiola grenulata (R. grenulata) was ordered from Shanxi Zhendong Genuine Medicinal
Materials Development Co., Ltd, China, and used for the study. The quantity of the salidroside
constituents of the underground parts were compared and the sourcing of roseroot raw material was
evaluated. Chemical analysis of roots and rhizome of R. Rosea namely the appearance, identification,
moisture, organic impurities, mineral impurities, residue on ignition, water-soluble extractives, fresh
weight of roots, and salidroside content were determined according to the National Pharmacopoeia of
Mongolia (NPhM) 2011. Microbiological analysis was performed in accordance with the requirements
of grade 3b specified in Annex 1 of the Order No. A / 219 of the Minister of Health dated May 30,
2017 to determine the degree of microbiological purity in medicinal products of roots and rhizome
raw materials.
Result:
The content of salidroside, the main biologically active substance of R.rosea plant, was 1.57% in
samples collected from Zavkhan province, 1.45% in samples collected from Khuvsgul province, 1.7%
in samples grown in China and 0.25% for 3-years-old samples and 1.89% for 4-years-old samples grown in the Botanical Garden of Medicinal Plants, Monos group, Mongolia. In addition, these raw
materials meet the general requirements for plant raw materials and microbiological parameters.
Conclusion
Samples of underground parts of R.rosea cultivated for 4 years in the Botanical Garden of Medicinal
Plants have the highest content (1.89%) of the salidrosde. Therefore, it is suggested that the roots
and rhizomes of R.rosea planted in the future can be standardized and used as a raw materials for
medicines.

Introduction:
Helianthus tuberosus L. is main source of inuline in pharmaceutical and food industry. Pharmacological studies of the plant have showed some important therapeutic properties such as anti-diabetic, anti-osteoporosis, anti-cancer and strengthening cardiovascular system, immune system.
Material and method:
Helianthus tuberosus L., which has been cultivated in Botanical Garden of Medicinal Plants of Drug Research Institute, Monos Group, was used as a research raw material. The aerial and below ground parts of the plants were harvested in September 2020. The content of inulin, the main active ingredient in the plant, was determined by spectrophotometry. Raw materials of the plant were processed in several ways and prepared for further use as a pharmaceutical raw material.
Result:
Inulin content in Sample 1 was 34.5 ± 0.76%, Sample 2 was 70.31 ± 1.25%, Sample 3 was
78.43 ± 0.44% and Sample 4 was 75.36 ± 1.42%. The inulin content and yield were the highest in samples prepared by heat and cold cutting methods.
Conclusion
According to the results of appearance, yield, inulin content and moisture contents during the different processings of plant materials, it can be considered that the most suitable method for preparing Helianthus tuberosus L. as a pharmaceutical raw material is the cutting followed by freeze-drying.

Introduction:
Since 1993, the Inula helenium L. plant has been planted in the production area (Bulgan
Province, Dashinchilen Sum) of the Traditional Hatchery Science and Production Corporation’s medicinal
plant introduction and cultivation experience. At the Drug Research Institute, there is also a botanical institute
for medicinal plants where it is grown. In traditional Mongolian medicine, the roots and rhizomes of Inula
helenium L. are used to reduce inflammation, boost immunity, enhance hunger, and improve intestinal
motility. Inula helenium L. roots and rhizomes contain biologically active compounds such as monoterpenes,
sesquiterpenes, phenols, flavonoids, and polysaccharides.
Methods:
The roots and rhizomes of Inula helenium L. were extracted with water and 70% ethanol at the
following ratios 1:10 (2% of WAC), 1:8, and 1:6 by partial maceration at 700C for 2 hours each, extracted
and concentrated. The dry extract was obtained by the spray drying procedure. High-performance liquid
chromatography for determining the content of alantolactone, thin-layer chromatography for qualitative
analysis. Spectrophotometer for determining the content of polyphenolic compounds, colored compounds
with Folin-Ciocalteu reagent for qualitative analysis. Spectrophotometer for determining the content of inulin, and colored compounds with phenol and sulfuric acid solutions for qualitative analysis.
Conclusion
In determining the content of polyphenolic compounds, inulin, and alantolactone in the dry extract
taken from the roots and rhizomes of cultivated Inula helenium L., the content of polyphenolic compound in dry extract A was 2.50±0.08%, and alantolactone was 1.39±0.11% in the raw material of the plant, while B dry the extract had a high concentration of inulin of 58.51±0.66%.

The Jerusalem Artichoke (JA) (Helianthus tuberosus L.) is an annual plant native to North America and widely distributed in Europe and Central Asia. The tuber of JA contains 80% water, 15% polysaccharide (Inulin etc.), 2% protein, and a small amount of starch and fat. Inulin is a polysaccharide that is widely used as a prebiotic, fat substitute, and sugar substitute. This substance has high biological activity and is contained in large quantities.
The purpose of this study was to standardize the quality and safety of dried tubers of JA. Standardization includes parameters such as microscopic analysis, identification, quantification, validation of methods following the guidelines issued by ICH guidelines, and quality, including safety analysis (appearance, moisture, mechanical impurities, heavy metals, microbiological purity).
The content of inulin was 64.17±1.25%. The mean relative standard deviation of method validation (RMS%) was 1.27%, 1.18%, 1.22%, and the relative mean standard deviation (RMS) of method precision was 1.94%. The specific absorbance was 307 nm. The correlation coefficient R2=0.9998 was obtained for the reference curve of the standard substance. The detection limit of the method was 2.64 μg/ml, and the detection limit was 7.99 μg/ml.
The method mentioned above has been confirmed to be suitable for the quantitative determination of inulin in the tuber of JA. Moreover, Microbiological purity and heavy metal requirements are met.
