“…In difficult cases, morphological identifi cation can be supported by histochemical analysis to detect diagnostic features of the specimen (Au et al, 2009). In addition, microscopy allows to trace contamination by non-plant materials, such as insects or even inanimate matter, which would go unnoticed in a DNAbased test, such as pieces of wire, nylon, soil, stones, or sand (Cuassolo et al, 2010;Michetti et al, 2019). Despite these undisputable advantages, microscopic diagnostics also has to face several challenges: for the often exotic species, monographies on their diagnostic characteristics are not available and have to be newly established.…”

“…Since they are often taxon-specific, in some cases even down to the species level, the morphological, anatomical, and microscopic characteristics of plant species are of great value for the purposes of scientific investigation and botanical quality control (Grazina et al, 2020). These characteristics can be used to verify plant authenticity, and to detect contaminations, adulterations, and substitutions in plant products (Michetti et al, 2019). Microscopic authentication refers to the analysis of structural, cellular and molecular features of herbal products using different forms of microscopy (Tam et al, 2006).…”

Microscopic Authentication of Commercial Herbal Products in the Globalized Market: Potential and Limitations

2020

Herbal products are marketed and used around the globe for their claimed or expected health benefits, but their increasing demand has resulted in a proportionally increase of their accidental contamination or intentional adulteration, as already confirmed with DNAbased methods. Microscopy is a traditional pharmacopoeial method used for plant identification and we systematically searched for peer-reviewed publications to document its potential and limitations to authenticate herbal medicines and food supplements commercially available on the global market. The overall authenticity of 508 microscopically authenticated herbal products, sold in 13 countries, was 59%, while the rest of 41% were found to be adulterated. This problem was extending over all continents. At the national level, there were conspicuous differences, even between neighboring countries. These microscopically authenticated commercial herbal products confirm that different magnifying instruments can be used to authenticate crude or processed herbal products traded in the global marketplace. The reviewed publications report the successful use of different magnifying instruments, single or in combinations with a second one, with or without a chemical or DNA-based technique. Microscopy is therefore a rapid and cost-efficient method, and can cope with mixtures and impurities. However, it has limited applicability for highly processed samples. Microscopic authentication of commercial herbal products will therefore contribute to raise public awareness for the extent of adulteration and the need to safeguard consumer safety against the challenges of globalization.

“…Por otro lado, en Argentina se encontró casos de adulteración en la comercialización de plantas bajo el nombre vulgar "vira vira", señalando los autores, que los empaques contenían especies diferentes a la declarada (Michetti et al 2019); de forma similar en Bolivia, se evidenció el reemplazo de plantas medicinales para su comercialización (Bussmann et al 2016). Entonces, referirse a una planta solamente por su nombre vernacular puede llevar a confusiones de especies y por ende un uso inadecuado de ellas tanto en el ámbito científico como en su uso tradicional, por lo que se requiere una identificación estricta del material vegetal.…”

Background: The use of plants for therapeutic purposes is a common practice in Peru and the world; however, there is a poor ethnobotanical, ethnopharmacological and toxicological information´s systematization, especially if the plant is a native species from a country where there is an inadequate sanity control. Culcitium canescens is a native plant from high Andean areas, widely used for its medicinal properties. This plant has five scientific

Aim and Objectives: The exploitation, adulteration and substitution of herbs is major hurdle for development of commercial natural products. Thus, the microscopic evaluation is the first step towards standardization of medicinal plant. A leaf from Sansevieria cylindrica Bojer ex Hook is examined both macroscopically and microscopically in the current study. Materials and Methods: Sansevieria cylindrica Bojer ex Hook (Asparagaceae) is an indoor ornamental plant. Macroscopic characteristics viz. size and shape, colour, odour and taste were studied. Microscopic evaluations were performed by means of high-resolution microscope. Anatomy of the leaves was examined by following standard method of section cutting. Results: The macroscopic assessment showed that the plant leaves are light to dark green in colour having highly fibrous structure. Stomatal constants of 230, 19.6% stomatal index, 53.34/mm2 vein islet number, and 79.12/mm2 vein termination number were noted in the leaves. Anomocytic stomata, unicellular trichomes, xylem fibres, oxalate crystals, vascular bundles, etc. were all revealed in detailed microscopy. Conclusion: The macroscopic and microscopic findings of the Sansevieria cylindrica leaf are applicable for standardization and authentication of plant.
