Water-propylene glycol extracts of medicinal plants are widely used as active components in therapeutic and cosmetic products for external use. However, sparse data on the extracting efficiency of water-propylene glycol mixtures and chemical composition of water-propylene glycol extracts of plant raw materials are available in the scientific literature. Usually the manufacturer documentation also provides information about characteristics of the products that are not related to their biological activity. The results of HPLC/MS/MS study of Matricaria chamomilla L. flowers have shown that water-propylene glycol and water-ethanol extracts are similar in the composition of phenolic compounds: the dominant compounds of water-propylene glycol extract of Matricaria chamomilla L. flowers are apigenin and its glycosides (apigenin-7-glucoside, apigenin-7-O-6-O-malonyl-D-glycoside, apigenin-7-acetylglycoside, acetyl-malonyl-apigenin-7-O-glycoside), as well as 5,4’-dioxy-3,6,7,3’-tetramethoxyflavone, cis- and trans-forms of 2-O-glucopyranoside 2-hydroxy-4-methoxycoric acid, 7-methoxycumarin. Spectral and analytical characteristics in the UV-visible range of the spectra of water-propylene glycol extracts of a number of medicinal plants most often used in the cosmetic industry were studied to reveal extracts with the highest protective properties against UV radiation in A and B areas (extracts of Salvia officinalis L. leaves, Matricaria chamomilla L. flowers, Achillea millefolium L. grass), free radicals (extracts of Camellia sinensis L. leaves, Hypericum perforatum L. herb), and the highest content of flavonoids (extracts of Hypericum perforatum L. herb, leaves of Salvia officinalis L.) were revealed. When extracting raw materials from the same batch, the optical density at a wavelength of 270 nm is associated with the content of flavonoids, antioxidants and dry matter by a functional relationship, which is very convenient for rapid control of extraction processes in order to obtain a product with reproducible characteristics. Formulas for calculating the content of antioxidants in extracts using the DPPH method in comparison with standard samples of rutin and gallic acid are derived. Interpretation of data on the antioxidant content in different extracts in comparison with other analytical parameters are also presented. Demonstrated high repeatability of the shape of the spectral curves of Matricaria chamomilla L. flowers extract, observed regardless of the source of raw materials can be used in combination with the individuality of the curve shape of the extracts of raw materials of different types as one of the authenticity criteria. The proposed UV-spectrometric method was used to study the dynamics of Matricaria chamomilla L. flower extraction under different process parameters (temperature, propylene glycol/water ratio in the extractant). It is shown that extraction of raw materials with 50% water-propylene glycol for 4 h at a temperature of 50°C is optimal.

The role of phenols in the influence of herbal extracts fromSalvia officinalisL. andMatricaria chamomillaL. on two-spotted spider miteTetranychus urticaeKochExtracts prepared from 2 medicinal herbs (common sageSalvia officinalisL. and German chamomileMatricaria chamomillaL.) were used in this study for biological control of spider mites. Their effect on mortality, fecundity, and development ofTetranychus urticaeKoch on English ivy (Hedera helixL.) was studied under laboratory and greenhouse conditions. The extracts were prepared by soaking freshSalvialeaves or dryMatricariaflowers in ethanol for 24 h, followed by evaporation, and finally suspension of the pellets in water. Full extracts and extracts without phenols were tested. TheSalviaextracts had a higher acaricidal activity thanMatricariaextracts, but the toxicity of both extracts to spider mite eggs was low. The toxic effect of fullSalviaextracts on larval stages and females ofT. urticaewas evident. More than 50% of larvae and females were killed by this treatment in 4 days. Besides, total fecundity of survived females was evidently lower. Mortality and low fecundity after fullSalviaextract application decreased the spider mite population by 76%. The toxicity ofSalviaextracts after removal of phenols strongly declined, so the negative effect of the fullSalviaextract on spider mites was connected with a high concentration of phenolic compounds. The toxic effect ofMatricariaextracts in all tests was much lower and no evident role of phenolic compounds in its extracts was observed.

The article provides an overview of the structural features of the natural populations of Humulus lupulus L. in the world and in Kazakhstan. Currently, the use in medicine of natural products, medicines and biologically active substances of plant origin is increasing. Significant parts of the medicinal raw materials are wild plants. The need for medicinal plant raw materials (medicinal plants) is not decreasing; the technology of its procurement and reproduction in natural conditions wants significant perfection. It is known that they have a milder, more complex effect on the human body and are used in the treatment of many chronic diseases. The growing anthropogenic impact on populations of valuable medicinal plants is decreasing their stocks of raw materials. In this regard, the study of biological characteristics and the development of scientifically based agricultural techniques for the cultivation of many medicinal plants are becoming relevant. Humulus lupulus L. (common hop) is a valuable medicinal plant. They are used as painkillers, sedatives, hypnotics for increased nervous irritability, sleep distur-bances, neuralgia, vegetovascular dystonia, mild coronary spasms, tachycardia, and in the early stages of hyper-tension. According to the classification of medicinal plant resources, Humulus lupulus L. is a plant with a wide range, but with a limited supply of raw materials. In places of growth of Humulus lupulus L. does not form large thickets [1]. Recently, a comprehensive approach has been applied in the study of natural plant populations, including ontomorphological and population-ecological studies. This makes it possible to objectively assess the state of the species in the cenosis and predict its future behavior. In this regard, a comprehensive study of the natural populations of Humulus lupulus L. is of great relevance. Hops (Humulus lupulus L.) is an important crop worldwide, known as the main flavor ingredient in beer. A diversified brewing industry requires a variety of flavors, superior technological properties and sustainable agro-nomy, which are the center of advanced molecular breeding efforts in hops. Hop breeders have been limited in their ability to create strains with desirable traits, however, due to unusual and unpredictable inheritance patterns and the associated non-Mendelian segregation of genetic markers [2]. The use of hops has recently been undergoing a new change, driven by a growing international preference for more intensely flavored beer, supported by the craft-brewing sector. This movement led to the introduction of much more hops at various stages of beer production and to an ever-growing search for new flavors. Some hop varieties have thus received particular attention, including several older typical hops mostly used to date, although an intensive search for new varieties dubbed "Green Gold" has also taken place. A large number of new exquisite varieties have been described and are increasingly appreciated in the market. Global hop growing areas have increased over the past 5 years, although total world beer production has declined over the same period, confirming the trend of using more hops per liter of beer. In addition, a wide range of pharmacological properties have been described for hops and its derivatives, namely antioxidant, anti-inflammatory and antitumor properties, which are of great importance for the pharmaceutical industry. The bioactivity of beer can depend on the use of hops, which can become an important tool for brewers aiming to develop functional products. Taken together, the compounds isolated from Humulus lupulus L. have a wide range of biological activity, such as anti-inflammatory action, antimicrobial action, antioxidant action, antiproliferative effects, cytochrome P450 effects, glucose metabolism effects, hormonal effects, lipid effects and sedative / hypnotic effects. Therefore, the purpose of this Chapter is to describe the importance of hops in this new direction of beer production, market overview of hops, varieties, forms and methods of use, composition, value in bioactivity of beer and new discoveries in research hops [3].

Developmental Features

The problem of biodiversity conservation and rational use of natural resources remains one of the most pressing problems for countries around the world. To maintain the stability of biological resources a sufficiently developed basis for their reproduction is required, which, in turn requires a preliminary study of the developmental features of individual organisms both in the natural environment and during their introduction into the cultural environment. A special place among the spice plants is occupied by the Lamiaceae Lindl. family. It is rich in medicinal and essential oil plants, which are widely used in family medicine, as well as in folk medicine and food industry, perfumery and cosmetic industries. Such plants include Origanum vulgare and Salvia officinalis. In addition, both plant species are added as phytobiotics to animal feed. The article deals with sterilization of seeds of medicinal plants Origanum vulgare L. and Salvia officinalis L. and the effect of sterilization methods on seed germination. For in vitro cultivation an aseptic, undamaged pure culture was obtained from the original plant material, and the most optimal method for sterilizing the seeds of these medicinal plants was chosen.

Sage plants (Salvia officinalis L.) were dried in the passive dryers in different times of the year. Different passive solar dryers were used to achieve the socio-economical benefits from drying the medicinal plants growing in Sinai area. Drying sage plants might be a source to increase the Bedouin income instead of cannabis or marijuana, especially if it is exported abroad. Four drying methods were used in this investigation to dry sage in two seasons, namely August 2009 and March 2010 before flowering stage. Plants were dried in an Unglazed transpired passive solar dryer with 100% exposure to direct sun-rays, in a greenhouse dryer covered with shading cloth with 50% exposure to direct sun-rays, and with 0% sun-rays while the medicinal plants were protected from sun i.e. in shaded barn. Investigations were carried out under the environmental weather conditions of Ismailia, Egypt. The study revealed that sage can be dried at different times of the year even before the flowering stage of the plants.
