Last in years Uzbekistan In the Republic medicinal plants cultivation, reproduction
work and them pharmaceutical to practice current to grow issues state on a scale current direction as
confession Our Republic Presidential Decree No. PQ-4901 of November 26, 2020 “On measures to
expand the scope of scientific research on the cultivation and processing of medicinal plants, and the
development of their seed production” in the decision new, promising medicinal plants scientific
basically study, their raw material standardization and pharmacopoeia requirements suitable quality
standards working exit task This is fixed. plant our country in the flora natural accordingly wide not
distributed and pharmacognostic features enough unexplored because of it scientific in terms of
research to do, morphological, anatomical and physicochemical indicators determination and
medicinal raw material as standardization criteria working exit pharmaceutical working release, local
medicinal drugs assortment in expansion current importance profession will reach.
The research purpose:
Spanish lavender (
Lavandula) grown in the local agroclimatic
conditions of Uzbekistan stoechas L.
) raw material. The research aims to determine the
morphological and anatomical structure of the plant, microscopic diagnostic signs, evaluate the main
physicochemical parameters (residual moisture, total ash content, insoluble ash content, heavy metal
content, etc.) based on pharmacopoeial requirements, and develop criteria for standardization as a
medicinal raw material.
Methods and styles: The above-ground parts (flowers, stems, and leaves) of Spanish
lavender ( Lavandula stoechas L. )
grown in the local agroclimatic conditions of Uzbekistan were
selected as the object of the study. Pharmacognostic analyses were conducted in laboratory conditions
based on the standards of the State Pharmacopoeia of the Republic of Uzbekistan and the European
Pharmacopoeia. The external morphological and anatomical characteristics of the plant were studied.
Pharmacopoeial methods were used to determine the main quality criteria from physicochemical
indicators, such as residual moisture, total ash content, ash insoluble in 10% hydrochloric acid, and
heavy metal impurities. The results were statistically processed, diagnostic signs were identified, and
recommendations for standardization of medicinal raw materials were developed.
Results: The external morphological characteristics of Spanish lavender ( Lavandula
stoechas L. ) specimens
grown in local agroclimatic conditions were clearly described: the stem of
the plant is four-sided, the leaves are opposite, thinly lanceolate, the surface is covered with soft hairs;
the flowers are purple, have a characteristic odor, and are rich in essential oil. According to the
physicochemical parameters, the residual moisture, total ash content, and ash insoluble in 10%
hydrochloric acid of the plant raw material were found to comply with the standards of the State
Pharmacopoeia of Uzbekistan. Based on the data obtained, the main diagnostic signs (morphological,
microscopic, and physicochemical parameters) were proposed for the standardization of Spanish
lavender raw material. The results of the study indicated the possibility of using this plant as a

medicinal raw material in local pharmaceutical production and provided a scientific basis for the
development of a draft of provisional quality standards for the national pharmacopoeia.
Conclusion:
Spanish lavender (
Lavandula) grown in the local agroclimatic conditions of
Uzbekistan stoechas L.
) was studied in detail for the first time from a pharmacognostic perspective.
The morphological and anatomical structure of the plant, microscopic diagnostic signs, and
physicochemical parameters (residual moisture, total ash, ash insoluble in 10% hydrochloric acid)
were determined and their compliance with the requirements of the national pharmacopoeia was
proven.
