Myrciaria (Myrtaceae) species have been well investigated due to their chemical and biological relevance. The present work aimed to carry out the chemotaxonomic study of essential oils of the species M. dubia, M. floribunda, and M. tenella, sampled in the Brazilian Amazon and compare them with the volatile compositions from other Myrciaria species reported to Brazil and Colombia. The leaves of six Myrciaria specimens were collected (PA, Brazil) during the dry season, and their chemical compositions were analyzed by gas chromatography-mass spectrometer (GC-MS) and gas chromatography-flame ionization detector (GC-FID). The main compounds identified in the essential oils were monoterpenes with pinane and menthane skeletons, followed by sesquiterpenes with caryophyllane and cadinane skeletons. Among the sampled Myrciaria specimens, five chemical profiles were reported for the first time: profile I (M. dubia, α-pinene, 54.0–67.2%); profile II (M. floribunda, terpinolene 23.1%, α-phellandrene 17.7%, and γ-terpinene 8.7%); profile III (M. floribunda, γ-cadinene 17.5%, and an unidentified oxygenated sesquiterpene 15.0%); profile IV (M. tenella, E-caryophyllene 43.2%, and α-humulene 5.3%); and profile V (M. tenella, E-caryophyllene 19.1%, and caryophyllene oxide 41.1%). The Myrciaria chemical profiles showed significant variability in extraction methods, collection sites, plant parts, and genetic aspects.

“…Matias et al (2016) performed histochemical tests on species of Solanum for phenolic compounds stained brown with ferric chloride and potassium dichromate reagents. Andrade et al (2017), Betim et al (2020) and Ribeiro et al (2021) also showed that phenolic compounds reacted positively with ferric chloride (brown color). Besides the idioblasts, D. kaki, and C. cainito leaves also have trichomes that contained phenolic compounds.…”

Active chemical compounds from medicinal plants are mostly secondary metabolites that can be histochemically tested. It enables the identification and localization of diverse secondary metabolites within the tissue, which is not possible with screening phytochemicals. In this study, the histochemistry of the leaf blades of Ericales plants i.e., cantigi (Vaccinium varingiaefolium (Blume) Miq.), persimmon (Diospyros kaki Thunb.), sapodilla (Manilkara zapota (L.) van Royen), and star apple (Chrysophyllum cainito L.) were evaluated. These species have been reported as folk medicines that have secondary metabolites. Each leaf tissue was observed under a microscope, and phytochemical compounds presence and location were detected by using specific reagents. The results showed that those four leaves contained phenols, flavonoids, and terpenes, while quinones were only found in cantigi leaves. The secondary metabolites were present in the idioblast of parenchymal and epidermal tissues. The persimmon and star apple leaves had secretory cavities in trichomes with terpenes and phenolic compounds.

“…The chemical composition of seed reserves can influence germination, vigor, and storage potential (Bewley et al, 2013). However, anatomical and histochemical studies of tropical seeds are still considered scarce (Barbosa et al, 2021;Ferreira et al, 2020;Ribeiro et al, 2021).…”

Ananas ananassoides (Baker) L.B.Sm. a bromeliad from the savanna: seed morpho-anatomy and histochemistry

et al. 2024

Ananas ananassoides (Baker) L.B.Sm. is a wild pineapple, commonly found in the savannas. This study aimed to describe the morpho-anatomy and histochemistry of its seed. The observations were made in the longitudinal and transverse sections, using an optical microscope. The cell arrangement in the seed coat, ripples in the integument, the ratio of embryo size and endosperm amount, and the number of strata in the aleurone layer are anatomical characteristics that may contribute to distinguishing this species. The starch in the endosperm, lipids and proteins in the embryo, constitute the seed's main nutritional reserves. The homogeneous embryo and phenolic compounds present in the seed coat and in the aleurone layer possibly contribute to the dormancy in this species. This study presents information relevant to the taxonomy and physiology of A. ananassoides, which represents contributions to the global knowledge of this species with a high potential as ornamental.
