“…The buildup of phenolics in Jatropha organs may play an important role in defence mechanisms against herbivores, fungi, and bacteria, as well as in interactions with the abiotic environment. Pessoa et al (2021) and Marques et al (2022) found metabolite buildup in the secretory cavity Fig. 6.…”

“…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. Secretory structures, like glandular trichomes, idioblasts, secretory cavities, ducts, and laticifers, are also of scientific interest.…”

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.
