“…An essential method used to obtain standardization of species products is microscopy (Rashid et al 2018;Majid et al 2021;Uza & Dastagir 2022). For the pharmacognostic standardization of medicinal plants, light microscopy is often used to describe the architecture and histochemistry of a plant (Rosa et al 2021;Abbas et al 2022;Uza & Dastagir 2022). According to Gissi et al (2022) and Marques et al (2022), anatomy and histology are essential for identifying and resolving taxa within a complex species at the species and generic levels.…”

Jatropha, a traditional medicinal plant known for its anti‐inflammatory, antimicrobial, anticancer, antiviral, antidiabetic, and anticoagulant properties, was the subject of our study. We examined the morphology and chemical composition of three Jatropha species using cross‐ and longitudinal sections of fresh samples, observed with light microscopy. Histochemical analysis was conducted using various reagents to reveal the metabolites present. Anatomically, the distinguishing feature among the three Jatropha species was the presence of secretory cavities. These structures were identified in the petiole and stem bark of J. multifida, while in J. gossypiifolia and J. curcas they were present in roots. The stem bark cells of J. gossypiifolia were roundish in shape, whereas the others were rectangular. Laticifers were detected in the leaves, petioles, and stem bark of all three Jatropha species, while idioblasts were present in almost all organs. Histochemical tests revealed that excretory idioblasts and laticifers in Jatropha species contained alkaloids, phenolics, lipophilic compounds, and terpenoids. The cuticle of non‐glandular trichomes contained terpenoids, while phenolic compounds were found within the secretory cavities. These findings contribute to the identification of Jatropha species and provide valuable insights for the selection and collection of specific plant organs containing bioactive compounds.

“…Zhao et al observed the number of vascular bundles in the stems of 24 Dendrobium species by means of microscopic quantitative analysis, which aided the identification of Dendrobium plants (Zhao et al, 2018). Scanning electron microscopy (SEM) has significant advantages in analyzing the appearance, size, and fine structure, and visually observe the characteristics of population tissues (Khan et al, 2019; Zha et al, 2019), especially in the microscopic identification of leaf samples (Muravnik & Shavarda, 2012; Rosa et al, 2021). Glandular and non‐glandular trichome are very important characteristic structures of Artemisia and their structure and distribution are related to the secondary metabolites of Artemisia plants.…”

Artemisia annua, Artemisia argyi, Artemisia absinthium, Artemisia leucophylla and Artemisia lavandulaefolia are five herbal species of Artemisia usually misidentified, adulterated or substituted in commerce. Using light microscopy, scanning electron microscopy and microscopic quantitative analysis, the transverse sections, morphological, powder and quantitative microscopic features of glandular trichome density and area were observed for correct authentication. The results indicated that microscopic characteristics such as the distribution of fiber bundles in the vascular bundle of the main vein, the shape of xylem, the density and type of non-glandular trichomes, the morphology of T-shaped non-glandular trichomes, the type of calcium oxalate crystals, and the number and size of glandular trichomes can be used to authenticate the five Artemisia crude herbs. Differences in the morphology and density of glandular and non-glandular trichomes are key features for the identification of five Artemisia species. Therefore, our study provides a more comprehensive microscopic identification diagram and additional microscopic evidence for the five Artemisia species. HighlightsThis study provides a more comprehensive microscopic identification diagram and statistical information on the glandular trichome density and area for accurate authentication of five Artemisia herbs using light microscopy, scanning electron microscopy and microscopic quantitative analysis.

“…SEM is an invaluable tool in observing the surface morphology of plant materials, due to the enhanced depth of field and high resolution that cannot be easily achieved with light microscopy (Shah, Celik, et al, 2019). Nowadays, SEM along with light microscopy are widely used to analyze micromorphological characteristics in many plant species (Akhtar et al, 2021; Majeed et al, 2020; Rosa et al, 2021; Shah et al, 2018; Ullah et al, 2019).…”

Alyssum nezaketiae is a local endemic species in gypsum habitats of Çankırı province in Turkey. In this study, I used field collected specimens of A. nezaketiae in a scanning electron microscopy examination of vegetative and reproductive structures of A. nezaketiae. The objective of the study was to investigate the micromorphological properties that define the species and that represent its adaptation(s) to the extreme environmental conditions posed by gypsum habitats. The epidermis had one to two rows at transverse sections of leaf and stem. Cortex was composed six to eight rows parenchyma cells at stem. A number of adaptations to xeric habitats were observed, including: dense silvery lepidote hairs on leaves and stems, small leaves, stomata on the lower surfaces of the leaves occurring in stomatal crypts, intense lignification in the central cylinder of the stems, and bundles of sclerenchyma in the pith region of stems. These can be interpreted as gypsophytic characteristics associated with physiological drought. Micromorphological properties of plant parts are discussed in relation to environmental conditions and possible constraint factors occurring in these gypsum habitats. Furthermore, these micromorphological studies contribute important taxonomic characters that are needed to help identify a species whose habitat is under threat from a variety of human activities.
