“…Specific stains, such as Astra blue, toluidine blue, safranin, or Lugol, are often used to stain specific cells. However, a morphological analysis may not always ensure accurate identification and other techniques, such as a chromosome count, [45,46], multivariate analysis of morpho-anatomic data [47], and scanning electron microscopy, can be used to try to identify a species [48]. All these techniques require time to prepare slides as well as reagents but may help to ensure the correct identification of the studied species.…”

Quality Control of Herbal Medicines: From Traditional Techniques to State-of-the-art Approaches

Herbal medicines are important options for the treatment of several illnesses. Although their therapeutic applicability has been demonstrated throughout history, several concerns about their safety and efficacy are raised regularly. Quality control of articles of botanical origin, including plant materials, plant extracts, and herbal medicines, remains a challenge. Traditionally, qualitative (e.g., identification and chromatographic profile) and quantitative (e.g., content analyses) markers are applied for this purpose. The compound-oriented approach may stand alone in some cases (e.g., atropine in Atropa belladonna). However, for most plant materials, plant extracts, and herbal medicines, it is not possible to assure quality based only on the content or presence/absence of one (sometimes randomly selected) compound. In this sense, pattern-oriented approaches have been extensively studied, introducing the use of multivariate data analysis on chromatographic/spectroscopic fingerprints. The use of genetic methods for plant material/plant extract authentication has also been proposed. In this study, traditional approaches are reviewed, although the focus is on the applicability of fingerprints for quality control, highlighting the most used approaches, as well as demonstrating their usefulness. The literature review shows that a pattern-oriented approach may be successfully applied to the quality assessment of articles of botanical origin, while also providing directions for a compound-oriented approach and a rational marker selection. These observations indicate that it may be worth considering to include fingerprints and their data analysis in the regulatory framework for herbal medicines concerning quality control since this is the foundation of the holistic view that these complex products demand.

“…It is usually consumed as an infusion or tea, and possesses a characteristic bitter taste. These infusions are commonly used in popular medicine and possess antimicrobial, analgesic, digestive, anti‐inflammatory, antioxidant, and other properties (Lázaro et al., 2013; Martínez et al, 2018; Nogueira et al., 2011; De Oliveira et al., 2013).…”

Beer is a fermented product principally composed of barley malt, water, hops, and additives, subjected to the action of appropriate microorganisms. However, the first beer production historical records reveal that, originally, beer had different characteristics from those of modern beers. It was a naturally fermented product made from cereals, fruit, and honey (Meussdoerffer, 2009). Hops were not always used in the formulation of beer. In the 8th century, a mix called gruit (containing rosemary, ginger, mugwort, yarrow, and heather) was commonly used in beer making (Hornsey, 2003). The use of hops became more common from the 9th century onward, and was very likely used at first because of its preservation properties, and not because of its bitter flavor (Morado, 2009). The common hop (Humulus lupulus) is a climbing plant belonging to the family Cannabaceae (Bedini et al., 2016). Its cultivation is restricted to two latitudes, one in the southern hemisphere and one in the northern hemisphere (between parallel 35° and 55°), and it is very difficult to grow in many countries (Morais, 2015), for example, in Brazil. In beer, hops mainly act on beer aroma, sensory bitterness, microbial stability, foam stability, flavor stability, and are a source of antioxidant compounds. These activities vary according to the hop variety, and the manner in which it is harvested and processed

Rocky outcrop environments at high altitudes have nutrient‐poor soil, where species are exposed to water scarcity and high solar radiation. Baccharis platypoda DC. occurs in such an environment and has a rigid and transparent secretion that covers the entire inflorescence. We analysed and compared the secretory structures and their chemical composition in female and male inflorescences of B. platypoda, a dioecious species, to explore chemodiversity within this species and assess potential differences between individuals. Our investigation also aims to understand the occurrence of these substances in the genus Baccharis L. Chemical compounds and secretory structures were similar in female and male inflorescences. There are glandular trichomes on the epidermis of the abaxial surface of bracts, and secretory ducts in the axis of the inflorescence, as well as in sepals, petals, and bracts. Histochemical tests were positive for phenolic compounds, flavonoids, proteins, pectin, and lipids, but not for mucilage. Flavonoid content varied between 6.24% and 9.81%, being higher in female inflorescences. Chromatography revealed the presence of several phenolic compounds, some terpenes, and other less frequent classes in both female and male inflorescences. We highlight that trichomes found on these surfaces produce abundant phenolic compounds. These act as natural defence agents, absorbing UV radiation and minimizing oxidative stress to plant cells. The chemical composition of the secretion covering the inflorescences may reflect adaptation and survival mechanisms of these organisms under extreme sun exposure.
