“…Most authors studying the genus Piper from a phytochemical point of view focussed their attention on the fruit, since it is the most relevant part of the plant for economical purposes. Our observations on the leaves are in agreement with other authors who showed these phytochemical features in other species of the Piper genus (Marinho et al 2011;Pires Jacinto et al 2018;Silva et al 2017;Bertocco et al 2017) From a phytochemical point of view, P. malgassicum is closely related to P. nigrum (Palchetti et al 2018(Palchetti et al , 2020 and used traditionally in the same way as a spice.…”

“…DC., and P. umbellatum Jacq. (Gogosz et al 2012;Raman et al 2012;Silva et al 2017;Santos et al 2018) However, amphihypostomatic leaves were found in P. sarmentosum Roxb. (Raman et al 2012) and amphistomatic in P. hispidinervum C. DC (Gogosz et al 2012) Concerning the anatomical aspects of the leaf, the microscopical analysis revealed how trichomes were not the prevailing secretory structures, but other specialized cells in the hypodermis, called idioblasts, had this function.…”

This is the first contribution about the histochemistry of vegetative and reproductive aerial organs in the genus Piper L. Piper malgassicum accumulates alkaloids and terpenes in the epidermis and the underlying layers of parenchyma, both in the leaves, in the stems and in anthers. Some idioblasts appear to contain a large amount of secondary metabolites. The micro-anatomical analysis showed peculiar secretory structures both in the leaves, in the anthers and in the ovary. Several lipid aggregates, alkaloid droplets and calcium oxalate crystals were observed in leaves and stems, indicating their role in defence strategies, mechanical support, and pollinators attraction. In the anthers, we observed elaioplasts whose content suggest an alternative and indirect function in pollination and defence against micro-organisms. Besides, some lipid aggregates surrounded by microtubules, detected in the anthers, were recognized as lipotubuloids. The tapetum was of secretory type. Alkaloids and terpenes were widely distributed in the plant confirming the important biological role of this type of biomolecules and its functional range. In the anthers, terpene and polyphenol inclusions appeared particularly abundant in the epidermal layer, whereas calcium oxalate crystals were observed close to the ovule in the ovary at maturity.

“…Moreover, the physicochemical properties of the corms of two endemic species, C. speciosum and C. robustum were compared with C. autumnale standard corm. Notably, the physicochemical properties of other medicinal plants such as Colchicum luteum, Piper callosum, Salacia macrophylla, and Heracleum persicum are evaluated by some previously performed studies (32)(33)(34)(35).…”

Background: Colchicum is a genus of the Colchicaceae family with various isolated compounds, especially tropolone alkaloids and flavonoids, which are used for osteoarthritis, gout, cancer, inflammatory diseases, jaundice, and sexual impotence in different societies. Objectives: The current study aimed to evaluate the phytochemical and physicochemical properties and anti-inflammatory activities of three Colchicum species. Methods: Total tropolone alkaloid, total phenolic/total tannin, and total flavonoid contents were determined using acidic potassium dichromate, Folin-Ciocalteu, and aluminum chloride methods, respectively. Moreover, the HPLC method was used for identification and quantitation purposes of tropolone alkaloids. Physicochemical properties of three Colchicum species, including macroscopic and organoleptic properties, solubility, foreign matter, ash values, and heavy metal contents, were evaluated. Besides, in vitro anti-inflammatory activities of the corms also were determined using the protein denaturation technique as a rapid screening method. Results: The highest levels of tropolone alkaloid, phenolic compounds, tannins, and flavonoids were observed in C. autumnale, C. speciosum, and C. robustum, respectively. HPLC analysis indicated the presence of colchicine, demecolcine, 2-demethyl colchicine, 3-demethyl colchicine, colchicoside, colchifoline, cornigerine, and N-deacetyl-N-formyl colchicine in these Colchicum species. The physicochemical properties of C. speciosum and C. robustum corms are appropriate compared to the standard Colchicum autumnale corm. Moreover, all Colchicum species exhibited high anti-inflammatory activities compared to standard drugs. Conclusions: This study demonstrated that the corm of the Colchicum species contained similar main compounds with different amounts, as well as appropriate physicochemical properties. Moreover, the valuable biological effects of these plants stimulate the cultivations on a large scale.

“…Da família Piperaceae, o elixir paregórico (Piper callosum), citado 7 vezes, é usado na medicina popular para combater febre e dores estomacais, e também no tratamento de gonorreia, tem ação repelente, adstringente, diurética, purificadora e hemostática. No entanto, não há relatos que comprovem, através de análises sistemáticas os seus efeitos (SILVA et al, 2017).…”
