“…Previous histochemical studies of phenols have been done (Coelho et al, 2012; De Souza et al, 2017). The histochemical results showed the main phenolic compounds were present in epidermal cells, which were consistent with the previous study of Solidago chilensis Meyen (De Souza et al, 2017). However, the finding was different from what was discovered in Bathysa cuspidata (Coelho et al, 2012), where phenolic compounds were present in stomatal bands, sponge tissue, and endothelial cells but not in all palisade parenchyma.…”

Needles of Juniperus rigida are used in Chinese traditional medicine for the treatment of brucellosis, dropsy, skin disease, and rheumatoid arthritis. This is the first study that reports anatomical structures of the J. rigida needles collected at different altitudes. The most common anatomical, phytochemical, and histochemical techniques and methods are used. The results show that anatomical structures and chemical composition change significantly at different altitudes. The main anatomical characters are significant xeromorphic structures (thick epidermis, hypodermis, and cuticle), a stomatal band, a developed vascular bundle, and a marginal resin duct. The xeromorphic structures become more pronounced with increasing altitude. The phytochemical and histochemical results demonstrate that the content of the main chemical compounds (phenols and terpenoids) basically increases at a higher elevation. Histochemical analysis localizes the phenols in epidermal cells, sponge tissue, endothelial layer cells, and stomatal bands, and the terpenoids in palisade tissue, sponge tissue, and the edge of the resin duct. This work reveals the relation between anatomy and chemistry in J. rigida needles, contributes to the quality control of its ethno-medicine, and provides the evidence to develop the commercial cultivation.

The aim. The aim of this work was to conduct a microscopic and phytochemical study of the seeds of chia (Salvia hispanica L.). Materials and methods. Chia seeds were examined macroscopically and microscopically. To study the qualitative composition of the main groups of biologically active substances, histochemical, microchemical and chemical reactions were used. Hydroxycinnamic acids were identified by paper chromatography. To obtain a lipophilic extract, a Soxhlet apparatus and an exhaustive chloroform extraction method were used. The study of the quantitative content of fatty acids was carried out by gas chromatography. The content of polysaccharides in the raw material was determined by the gravimetric method. According to the SPhU method, the raw material swelling index was determined. Results. The main macro- and microscopic features of chia seeds have been established. Histochemical reactions, microchemical reactions made it possible to establish the presence of mucus and fatty oils in chia seeds. With the help of chemical reactions, the presence of flavonoids in the raw material was established. The quantitative content of fatty oils is 24.0±1.2 %. The content of water-soluble polysaccharides in the whole raw material was 4.01±0.07 %, in the crushed raw material - 5.04 ± 0.05 %. As a result of determining the swelling index, it was found that this indicator for the whole chia seeds was 20, and for the crushed ones – 17. The content of hydroxycinnamic acids in the chia seeds was 1.07±0.03 %. 9 fatty acids have been identified, among which linoleic acid predominates in terms of content. Conclusions. The presence and quantitative content of mucus, fatty oils, water-soluble polysaccharides, flavonoids, hydroxycinnamic acids, fatty acids was confirmed in the seeds of chia (Salvia hispanica L.). The obtained data can be used to develop regulatory documentation for chia seeds in order to use this raw material in pharmacy and medicine

“…This genus is widely used in traditional medicine by many countries, particularly for the treatment of inflammatory and diuretic problems (Blumenthal et al 1998). Phytochemical studies have identifi ed the presence of monoterpenes, sesquiterpenes, sesquiterpene lactones, triterpenes, steroids, saponins, flavonoids, and cinnamic acid derivatives (Souza et al 2017).…”

Solidago microglossa is used as an anti-infl ammatory agent in traditional Brazilian medicine, and this work evaluated the anti-infl ammatory potential of the crude ethanolic extract of the fl owers of S. microglossa in vivo, as assayed by paw edema models induced by carrageenan, prostaglandin E2, bradykinin and compound 48/80. In the chemical profi le, we identifi ed compounds by electrospray ionization mass spectrometry and quantifi ed them by HPLC-DAD. Additionally, this study analyzed the potential to activate the in vitro transcriptional activity of PPARγ, which is a nuclear receptor linked to the anti-infl ammatory response. It was possible to identify fi ve compounds: quinic acid, quercetin, chlorogenic acid, hyperoside, and rutin. In the paw edema evaluation, it was possible to show the potential of reducing edema during the infl ammatory process.The crude ethanolic extract of the fl owers of S. microglossa activated PPARγ compared to the full agonist rosiglitazone and in a dose-response manner. It is possible to conclude that the extract of the fl owers of S. microglossa showed anti-infl ammatory activity, and the phenolic compounds present in this species might be responsible for this activity.
