Article Abstract
Coffee agro-waste is a potential source of polyphenols with antioxidant activity and application in the food and cosmetic trades. The usage of these byproducts persists as a challenge in the industrial landscape due to their high content of purported toxic substances hindering management. This study presents a green extractive process using pulsed electric field (PEF) and microwave assisted extraction (MAE) to recover polyphenols from coffee parchment and two varieties of pulp, posing quick processing times and the use of water as the only solvent. The performance of this process with regard to the bioactivity was assessed through the Folin-Ciocalteu assay, total flavonoid content, DPPH, ABTS and FRAP antioxidant tests. The phenolic composition of the extracts was also determined through HPLC-MS and quantified through HPLC-DAD. When compared to treatment controls, PEF + MAE treated samples presented enhanced yields of total phenolic content and radical scavenging activity in all analyzed residues (Tukey test significance: 95%). The chromatographic studies reveal the presence of caffeic acid on the three analyzed by-products. The HPLC-DAD caffeic acid quantification validated that a combination of MAE + PEF treatment in yellow coffee pulp had the highest caffeic acid concentration of all studied extraction methods.

Ethnopharmacological Relevance: Ocimum gratissimum L. commonly known as basil, is an herb-like plant frequently mentioned in ethnopharmacological studies due to its widespread availability in local communities and its widespread use in treating inflammatory conditions. In a previous study, we demonstrated that aqueous extracts of Ocimum gratissimum (OGE), which are rich in plant polyphenols such as caffeic acid and isoflavones, can protect skin cells from UVC-induced inflammation and damage in migration and proliferation.

Xenopus embryo serves as an ideal model for teratogenesis assays to observe the effects of any compounds on the cellular processes crucial for early development and adult tissue homeostasis. In our screening of a chemical library with frog embryo, caffeic acid phenethyl ester (CAPE) was found to upregulate the FGF/MAPK pathway, disrupting germ layer formation in early development. Exposure to CAPE interfered with the formation of anterior-posterior body axis and of ectodermal derivatives such as eyes, dorsal fin and pigment cells.

Caffeic acid is a key indicator of wine quality, but its sensitive and accurate detection remains challenging due to the lack of high-performance sensing materials. Metal/N-doped porous carbon (M/NPC) electrocatalysts with abundant catalytic sites are promising to address this issue. Herein, a FeCo nanoalloy encapsulated in NPC (FeCo@NPC) was designed and synthesized via a "covalent organic framework (COF) adsorption-pyrolysis" strategy.

Chlorogenic acid (5-CQA) is a caffeic acid ester widely accumulated in higher plants. It plays roles in defense against biotic and abiotic stresses. As its biosynthetic pathway shares common enzymes and intermediates with that of lignin, 5-CQA has long been hypothesized to be involved in lignin formation.

The current investigation was designed to explore the chemical composition, antioxidant capacity, enzyme inhibitory activity, and cytotoxic potential of four different extracts (Ethyl Acetate, Ethanol, Ethanol/Water (70%) and Water) derived from the aerial parts of . In vitro, assessments were performed utilizing diverse antioxidant assays, along with evaluations of neuroprotective enzyme inhibition targeting acetylcholine and butyl choline enzymes, as well as antidiabetic activities against α-amylase and α-glucosidase and a potential candidate for a tyrosinase inhibitor. LC-ESI-QTOF-MS identification provided a total of 70 compounds in the extracted samples of , including kaempferol 3-(deoxyhexosyl-hexoside)-7-hexoside, rutin, quercetin dideoxyhexoside, caffeic acid hexoside, quinoline alkaloids, morphine derivatives, and scoulerine.
