“…Several studies have shown that plant secondary metabolism react positively or negatively to environmental conditions and to phenological changes, resulting in a complex and intricate response system. [32][33][34][35][36][37][38] In this work with A. purpurea it is shown once again that the secondary metabolism is more complex than initially anticipated. The highest production of total alkaloids detected coincides with the last month of drought and with the onset of the rains, Table 8.…”

“…An organ-specific antibacterial activity was demonstrated in this Annonaceae specie by [39] using methanolic extracts. [37] Therefore, an inclusive analysis of environment and phenology is necessary to understand the modulation of secondary metabolism, with an alternative being the study of young plants wherein the phenological factors can be separated. [40] The influence of season on phytochemical profile and thus bioactivity might be attributed to environments conditions as well as different phenology stages.…”

“…Without isolating a single factor, it is impossible to link the increase in secondary metabolite production to factor unique, as the other factors have also proven to affect secondary metabolism. [37] Therefore, an inclusive analysis of environment and phenology is necessary to understand the modulation of secondary metabolism, with an alternative being the study of young plants wherein the phenological factors can be separated. [9] The extracts of the roots were always more potent against the three tested phytopathogens than those of other tissues, a fact that could be associated with the constitutive metabolite profiles.…”

Annona purpurea grows in the areas of low elevation in deciduous forests of Mexico, those areas have marked rainy and dry seasons. This species produces more than 30 bioactive alkaloids that could have potential in the control of phytopathogens. This research provides data on the variation of the content and number of alkaloids during an annual cycle and the associated inhibitory potential of the compounds against three phytopathogenic fungi. For one year, alkaloidal extracts of stems and leaves were obtained every two months. The extract profiles were determined by gas chromatography with tandem mass spectrometry and their antifungal activity was examined in vitro. The alkaloids, annomontine and oxopurpureine, obtained from the roots and leaves, respectively, were also evaluated individually. The yields, profiles and activities of the extracts, as well as the abundance of annomontine and oxopurpureine in the extracts, were contrasted with the seasonality and phenological phases of the plant. The data indicate that the alkaloid content was higher at the height of the dry season. High yields also occurred during flowering. The strongest inhibitory effect was obtained from the root extracts during the last month of dry season. This finding seems to be explained by the higher chemodiversity of alkaloids in extracts from this season. Annomontine and oxopurpureine inhibited all three phytopathogens; however, they were not solely responsible for the activity of A. purpurea.

“…D. ecastaphyllum species grow along beaches, dunes, and mangroves, therefore, the levels of salinity, temperature, light, nutrients, and water availability diverge. It has been demonstrated in several studies that these abiotic factors effectively influence the chemical composition of plants, particularly the production of secondary metabolites among which flavonoids (Prinsloo & Nogemane, 2018).…”

For the first time, the anti-hemolytic activity and the enzyme inhibitory activities of Dalbergia ecastaphyllum leaves extracts were tested against α-amylase, α-glucosidase, lipase, acetylcholinesterase, butyrylcholinesterase, tyrosinase and hyaluronidase. The phenolic profile of the obtained extracts was also investigated by high-performance liquid chromatography with photodiode array detection (HPLC-PAD). The extracts showed inhibitory activity against all enzymes evaluated, with the highest inhibitory activity reported for the enzyme hyaluronidase (28.28 ± 2.43 to 72.19 ± 1.40 μg mL-1). The obtained extracts also demonstrate anti-hemolytic activity (52.22 ± 1.62 to 71.17 ± 1.82%). Among the phenolic compounds identified, protocatechuic, vanillic and β-resorcylic acids were the most abundant (1.13 ± 0.06 to 2.53 ± 0.06, 0.90 ± 0.06 to 2.19 ± 0.06 and 1.03 ± 1.62 to 22.11 ± 1.62 mg L-1, respectively). In the statistical analysis, a significant correlation was found between the flavonoids content and all enzymes inhibitory activities. The present study showed that D. ecastaphyllum leaves extracts may have the potential to be used in the therapeutic treatment of several diseases such as Alzheimer, Parkinson, type 2 diabetes mellitus, hyperglycemia, and pigmentation, as well as those associated with oxidative stress.

Insect infestations continually endanger stored goods, underscoring the significance of discovering eco‐friendly insecticides for pest management. Essential oils (EOs) from different parts of Toddalia asiatica (leaf, fruit and branch) were extracted by hydrodistillation and analyzed by GC‐MS. Carvene, p‐cymene and muurolene are the principal compounds of T. asiatica leaf (TAL), T. asiatica fruit (TAF) and T. asiatica branch (TAB) EO respectively. Our work aimed to assess the contact toxicity and repellent effects of EOs on two storage pests, Tribolium castaneum and Lasioderma serricorne. All tested EOs exhibited obvious contact toxicity, especially, TAL EO against T. castaneum (33.48 μg/adult) and TAF EO against L. serricorne (16.42 μg/adult). Repellency tests revealed that TAL and TAF EOs, at a concentration of 78.63 nL/cm2, achieved nearing 100% efficiency against T. castaneum. These results suggest that EOs of T. asiatica could be used as effective botanical insecticides for managing stored‐product insects.
