Abstract:

Summary. Extracts of Echinacea spp. are widely used as therapeutic immunostimulants with such activity being attributed in part to the alkamide fractions of these plants. Using high performance liquid chromatography, the levels of 8 alkamides, including 2 tetraene alkamides (dodeca-2E, 4E, 8Z, 10E/Z-tetraenoic acid isobutylamide), were quantitatively determined in 2 Australian-grown Echinacea spp. Overall, the levels of alkamides in Australian-grown E. angustifolia were found to be comparable with levels obtained in this study and other studies for USA and European Echinacea spp. However, resu

Abstract:

The alkamide content and specific tissue localization in the cypselae of Heliopsis longipes were investigated using gas chromatography–electron ionization mass spectrometry (GC-EIMS) and multiphoton fluorescence microscopy (MPFM). GC-EIMS analysis identified two olefinic alkamides: affinin (spilanthol) and N-2-methylbutyl-2E,6Z,8E-decatrienamide. Microscopic analysis revealed that alkamides are localized within the cotyledons, and specifically compartmentalized in lipid bodies, highlighting their spatial organization. The linear unmixing of fluorescence emission fingerprints showed that affini

Abstract:

Zanthoxylum species have long been utilized in traditional medicine; among their various properties, they provide an analgesic effect. Central to this medicinal application are alkamides, a class of alkaloids characterized by their unsaturated fatty acid chains. These compounds are particularly noted for their distinctive alleviation of tingling and numbing effects, which are beneficial in dental pain management and local anesthesia. This review synthesizes the existing phytochemical research on alkamides derived from 11 Z. species, focusing on their chemical properties, pharmacodynamics and c

Abstract:

Alkamides have been observed to interact in different ways in several superior organisms and have been used in traditional medicine in many countries e.g., to relieve pain. Previous studies showed that affinin when applied to other plant species induces prominent changes in the root architecture and induces transcriptional adjustments; however, little is known about the metabolic pathways recruited by plants in response to alkamides. Previous published work with Arabidopsis seedlings treated in vitro with affinin at 50 µM significantly reduced primary root length. In tomato seedlings, that con

Abstract:

We investigated patterns of variation in alkamides and cichoric acid accumulation in the roots and aboveground parts of Echinacea purpurea (L.) Moench. These phytochemicals were extracted from fresh plant parts with 60% ethanol and quantified by high performance liquid chromatography (HPLC) analysis. Concentrations of alkamides and cichoric acid were measured on a dry-weight basis (mg·g–1). For total alkamides, concentrations among individual plants varied from 5.02 to 27.67 (mean = 14.4%) in roots, from 0.62 to 3.42 (mean = 1.54) in nearly matured seed heads (NMSH), and 0.22 to 5.25 (mean = 0

Abstract:

Background Alkamides are plant-specific bioactive molecules. They are low molecular weight N-substituted α-unsaturated acyl amides that display biological explicit activities in different organisms from bacteria, fungi, insects to mammals and plants. The acyl chain has been proposed to be biosynthesized from a fatty acid; however, this has not been demonstrated yet. Heliopsis longipes (Asteraceae) accumulates in root a C10 alkamide called affinin in its roots, but not in leaves. The closely related species Heliopsis annua does not produce alkamides.

Abstract α-Sanshool is an alkamide isolated from the stem bark of Zanthoxylum liebmannianum, a Mexican medicinal plant known as Colopahtle. Our research group has reported that the intraperitoneal administration of α-sanshool induces tonic-clonic seizures in mice. In the present study, we investigated the convulsive effect of this alkamide and elucidated its mechanism of action by comparing with well-known convulsive and anticonvulsive drugs in an in vivo approach. α-Sanshool showed a potent (ED50 [CL 95%]=3.06 [2.92–3.22] mg/kg) and immediate (2±2 s) seizure effect after the intraperitoneal a

Abstract:

The genus Piper is the largest among plants of the Piperaceae family. Phytochemical studies on various piper species indicate the presence of bioactive compounds, with alkamides being among the most prominent. Piperine is well studied, and is usually found in abundance in most species. Guineensine is an alkamide that merits particular interest and, until now, has received less scientific attention. Therefore, in the present review, we discuss guineensine’s isolation, synthesis, and pharmacological activity. Data were collected from 1974 to 2024. Databases including PubMed, Google Scholar, and

To determine the level of salt tolerance of the medicinal plant Echinacea, the physiological and biochemical characteristics of E. purpurea, E. pallida and E. angustifolia exposed to different NaCl levels (0, 50, 75, and 100 mM) were evaluated under hydroponic culture. Dry weights of shoots and roots were not affected by salinity; however E. purpurea and E. pallida exhibited higher survival rate than E. angustifolia, which also showed high salt injury index and electrolyte leakage compared to the other two species.
