The main indicator of the quality of herbal substances is the content of biologically-active agents in the organs and tissues of the plant. The chemical composition is subject to fluctuations under the influence of many factors and depends on the vegetation regime. The chemical composition (of the plant) fluctuates depending on many factors, among them, in no small measure, the vegetation regime.

Each plant has its own specific requirements for climatic conditions that allow its life cycle to be successfully completed. Each plant needs certain climatic conditions for the harmonious life cycle flow.

An own optimal stage of vegetation for gathering raw materials is typical for each species and varieties of plants.

These are important environmental conditions:

  • The amount of heat and light that affect the vegetation duration, the substances accumulation and the plant weight.
  • Humidity and amount of precipitations in the growing area. For example, xerophytic plants feel good in arid conditions but do not tolerate excessive moisture.

For example, xerophytic plants endure the long lack of moisture well and can grow in arid conditions but an excessive moisture can harm them.

Vice versa, plants-hygrophytes are not able to live safely in arid conditions.

  • Altitude also has a great impact. Mostly, the plant accumulates more active substances at the height that is closest to the natural growth conditions.
  • A type and composition of the soil on which the plant has great influence on its growing. This is often a key factor in the mineral accumulation dynamics.
  • One should not miss the influence of anthropogenic factors, as well as on the type of agricultural technology of cultivated plants management.

The human impact during the plants cultivation, including the type of agricultural machinery used for this shall also be taken into account.

The dynamics of the active compounds content depends not only on climatic and geographical conditions, but also largely depends on the group or type of accumulated substances.

Fluctuations in the active substances content (or active substances accumulation dynamics) in the plant are caused not just by climatic and geographical factors, but depend on the group and type of these substances.

For example:

  • the alkaloid accumulation dynamics is subject to significant changes – it can significantly vary depending on the height of the plant growth.
  • the determining condition for the formation and accumulation of glycosides is a high illumination and solar activity level (in simple words, sufficient solar radiance) High nitrogen content in the soil, a large precipitations amount and high humidity reduce the content of glycosides in the plant organs of the plant.
  • the active substances accumulation goes better when the plant grows in its native territory in contrary to the cases when it is deliberately transferred to other regions)

Essential-oil-bearing plants of a temperate zone (mint, marjoram, balm lemon) accumulate an increased essential oil amount at moderate air temperature and high humidity and plants of hot weather is for southern zones in hot weather. The accumulation organ is also due in no small part to the dynamics of the active compounds accumulation. The highest content of substances in the target organ is individual for each but it has its own features. For example, if the active compound is contained in the flowers, it will be the best option to collect the flowers in the midst of flowering. It is advisable to collect substances in fruits or seeds during the period of active fruiting.

Thus, many factors affect the accumulation and content of substances in medicinal plant raw materials and our company pays special attention to these factors. We carry out a benchmarking analysis of different types of herbal substances growing in large areas and choose the best ones in quantitative and qualitative content of active compounds for the final product manufacturing.

Our priority is the collection of raw materials specifically in Siberia - this region has the most severe climatic conditions. Significant temperature jumps during the calendar year force plants to accumulate active substances for the future, so that the content of useful substances in plants growing in a harsh environment is higher than in plants habituated to a milder climate.
