İn recent times considerable concern has been addressed to accepting the benefits of plant compounds and for creating a natural lifestyle. In the presented manuscript the herbal cosmetic products used in Turkiye have been evaluated. In all 140 plant taxa were investigated from the traditional uses.The results revealed that 40 were used for hair care, 28 as photoprotective agents, 25 for hair loss, 24 for skincare, 19 as perfumes, 17 for bad breath, 11 for dandruff, 10 for making soap, 7 for the mouth and dental hygiene, 6 against foot odor/sweating, and 4 for other purposes. The most commonly used herbal cosmetic plant taxa are; walnut (Juglans regia), common nettle (Urtica dioica), grape (Vitis vinifera), chamomile (Matricaria chamomilla), and true laurel (Laurus nobilis). Walnut is most commonly used to treat the hair loss, the toothpick-plant (Ammi visnaga) in moral hygiene and the chaste tree (Vites agnus-castus) to decrease odor and sweating in feet.

The article provides information on the discovery of new spreading ar- eas in the Botanical-geographical regions of Absheron and Gobustan, as well as phytocenoses formed in the middle part of the Caspian coast. In this regard, the “map on the new distribution area of plant species in the botanical-geographical regions of the Caspian coast” of those species registered in the vegetation cover of the territory was com-piled for the first time on the scale of 1:600000, as well as “map of the middle part of the Caspian coast” 1:5000. Ecological-geobotanic studies and systematic taxon studies were carried out in the middle part of the Caspian coast. During ecologicalgeobotanic researches in the central part of the Caspian coast in Ab-sheron and Gobustan botanical-geographical regions new distribution areas of the following species have been identified: Suaeda forrsk be- longing to the family. Chenopodiaceae Vent ex. Suaeda heterophylla Kar.et Kir belonging to Scop genus, Atriplex turcmenica (Moq.) Boiss belonging to Atriplex L., Salsola nitraria Pall., in the genus Salsola L., Erysimum caspicum N. Busch be- longing to Brassicaceae Burnett. Family, Erysimum L. genus, Astragantha falca- tus Lam. belonging to Fabaceae Lindl. Family, Astracantha Podlech.genus and Scrophularia divaricata Lebed belonging to Scrophulariacae Juss. Family and Scrophularia genus.

The purpose of this paper is to study the correlation between the colors of medicinal plants' flowers and their pharmacological effects on the human body. It has been known from traditional herbal medicines that certain medicinal plants with the same color of flowers have similar effects on the body. By com- paring the same color of flowers of medicinal herbs, we have found that there is a shared effect amongst medicinal plants with the same color flowers. Our findings conclude that purple flowering herbs are mainly adaptogenic and also support the immune system, blue flowering herbs have anti-inflammatory properties, red flowering herbs will affect the blood, yellow flowering herbs help with digestion, white flowering herbs are mostly sedative or affect the nervous system, and herbs with no flowers help provide nutrients to the body. In the future, more in- vestigation is needed to determine specific constituents in plants that are respon- sible for their pharmacological actions. The study of the correlation between col- ors of flowers and their healing abilities will help us select the correct medicinal plants for these future clinical studies.

In this study, we choose Medicago falcata L., also known as “alfalfa” or “Lucerne”, it belongs to the family Fabaceae. M. falcata L. is a perennial flower- ing plant. M. falcata L. produce different kinds of secondary metabolites such as saponins, flavonoids, coumarins, alkaloids, phenols which have antimicrobial and antibacterial properties which play medicinally vital role. The chemical constitu- ents obtained from plant can cure high cholesterol, kidney problems, asthma, stomach, bladder problems and menopause issues. The aim of the study is to ob- tain the flavonoid-saponin complex of M. falcata L., which is common in the Azerbaijani flora, and to examine its antioxidant activity. The isolated flavonoid- saponin fraction when analyzed by A.B.T.S. and D.P.P.H. showed high activity. The technical effect of the claimed invention consists in expanding the raw mate- rial base of medicinal plants, namely the base of crescent alfalfa (M. falcata L.) and the sum of the flavonoid-saponin complex of biologically active substances with antioxidant activity isolated from it.

The use of nanotechnology in agricultural practice has great potential to increase crop yields. The effects of n anoparticles on seed germination, growth stimulation, metabolic rate, biochemical and physiological processes have been studied in detail in a number of scientific studies. In this studies, it has been shown that the treatment seeds of corn by nanoparticles improved the physiological and biochemical parameters of plants under drought. The effect of nanoparticles Fe2O3, ZnO and TiO2 (size = 18.05 nm) at concentration 1.0 ppm was investigated to improve drought tolerance. The leaves and stems of the seedlings of corn (Zea mays L.) in different stages of growing were used for assessing various physiological and biochemical traits. The middle portion of the leaf was used for chlorophyll composition and enzyme activity studies. In experiments, the effect of nanoparticles on the seed germination, enzyme guaiacol peroxidase (GPx) activity, chlorophyll content in the leaves were determined. The nanoparticles positively affected growth, chlorophyll contents and enzymatic antioxidants.

İn article, Colutea komarovii Takht. distributed in Nakhchivan Autono- mous Republic, its position in the world flora and the phytocenoses formed by it are presented. At the result of conducted studies, due to the small population of this species and negative effects of zoogenic and anthropogenic factors it has been included in the protection status of Critically Endangered -CR B1ac (ii,iv); C2a(i) as a rare species. The condition of the species in nature has worsened due to the effects of continuous drought during last 3 years. This species was intro- duced in the collection of rare plants in the Botanical Garden and Institute of Dendrology.

On the territory of the Azerbaijan Republic, significant research has been carried out in the field of biomonitoring, bioindication and biotesting of components of natural landscapes. The development of these studies is relevant both from scientific and practical points of view by conducting systematic re- search in the field of biomonitoring, bioindication, and biotesting in the arid zone of the country as a unified landscape system, considering the possibility of using the results obtained in the field of tasks the development needs of the current and prospective economy.

The present paper is devoted to species composition, taxonomic status, distribution, and monitoring opportunities of lichens and mosses in the Bozdag mountain range. In general, 29 lichen species belonging to 22 genera, 17 families and 30 moss species belonging to 21 genera, 12 families were detected in Boz- dag. Lecania triseptata, Lecanora gllabrat species of lichens and Leskea polycar- pa, Leucodon immerses species of mosses have been recommended for biomoni- toring.Lichens and mosses of different origins of the Bozdag mountain range entered the study area at different times. It is known that the Poltava-type tropical flora dominated during the Oligocene. This tropical flora had a Poltavian tropical char- acter of the Caucasian flora in the early Neogene. In the early Oligocene and Ne- ogene, Lecidea, Lecanora, Caloplaca were widespread in the Caucasus. Shrubby epiphyte and epigey lichens are tolerant to atmospheric pollutants. Indi- cator species for use in the biomonitoring system have been identified. Lichen species such as Lecania triseptata, Lecanora gllabrat and moss species, such as Leskea polycarpa, Leucodon immerses are recommended for use in biomonitor- ing.

The article deals with the topic of species diagnosis in the genus Di- phasiastrum. At the moment, all the methods available to researchers require the removal of whole plant samples or parts of plants from populations. In this paper we propose a new express method for obtaining morphometric data of species of the genus Diphasiastrum without plant damage and give its hardware implemen- tation. The method allows the identification of species directly in the field. Field and desktop testing of the proposed method was carried out. The low variance of repeated measurements of species-specific traits suggests that the method is suitable. Three new locations of Diphasiastrum in the Moscow region have been discovered and described. The plants were described according to a set of diag- nostically relevant qualitative and quantitative indicators and identified as D. complanatum (L.) Holub subsp. complanatum. For each finding, a standard de- scription of the biotope is given and a conclusion is made as to the degree to which the location is potentially suitable for the long-term existence of the species population. We consider the proposed method to be potentially suitable for many members of the Lycopodiaceae family. The relative rarity of many of these plants in nature makes the appearance of the method timely.

The forests of the Caucasus are one of the most important regions of the taxonomic diversity of ferns. Here are 70 species and 29 genera, or 64% of genera and 44% of species of ferns of Eastern Europe as given by Cherepanov, with exception of hybrid and adventive ferns. Critical revision of the forest ferns of the Caucasus made possible to identify two new genera in the flora of the region (Cyrtomium, Onoclea). In general, as a result of taxonomic revision of the number of fern families of the Caucasus increased from 4 to 20, and the number of genera - from 23 to 31. New for the flora of Eastern European were 20 species and hybrids of the species range, 5 subspecies: Pteris vittata, Ad- iantum cuneatum, Cyrtomium falcatum, Dryopteris remota, D.caucasica, D.atrata, D.ambroseae and others. For the first time in the Caucasus were found Botrychium virginianum, Onocle sensibilis, Cystopteris dickieana and Dryopteris expansa. The most favorable for the development and dispersal of ferns in the Caucasus were forest areas with moderately warm and humid climate. At the same time, along with the humidity, the most important factors that influence the spread of ferns were the degree of rocky and stony habitats and the nature of slope exposures.
