Common Names: Arabian coffee
Study links specific molecular differences to aromatic profile of specialty coffees, helping distinguish high value market produce. Important for producers and consumers seeking unique coffee flavors.
Researchers isolated phyllospheric bacteria from coffee plants to combat yellow coffee rust, a major phytosanitary issue in Peru. Two strains showed high inhibition of rust spore germination, offering a natural biocontrol option for coffee growers.
Researchers studied small RNAs during coffee plant development, identifying specific types like miRNAs and tRFs. They found a co-expression pattern in resistance genes across all stages, with miRNAs showing stage-specific accumulation related to hormonal responses and transcription factors. This research provides insights into plant growth regulation.
Plant-derived bioactive compounds show promise in improving metabolic and immune functions in patients with metabolic disorders. This review highlights the therapeutic potential of phytochemical formulations in alleviating conditions like obesity and diabetes. Further research and clinical trials are needed for validation.
Developed a natural phytocosmetic with coffee pulp extract rich in antioxidants and antibacterial properties. Promising potential for pharmaceutical and cosmetic applications.
This study examined the impact of different roasting temperatures on the chemical composition and flavor of coffee beans. Roasting at 150℃ resulted in increased compounds but decreased umami and sourness. Roasting at 210℃ increased flavonoids and caffeine but also produced aldehydes, ketones, sulfur compounds, and pyrazines. Analysis showed separation of beans based on roasting temperature and time.
This study identified coffee samples from Nepal and measured their antioxidant activity and phenolic content. Roasting increases antioxidant activity but decreases phenolic content.
Scientists sequenced and characterized the mitochondrial genome of L., an important crop. This will enhance evolutionary studies, molecular breeding, and the development of molecular markers for improved agricultural practices.
Scientists discovered six new sesquiterpenes (1-7) and one new sesquiterpenoid (3) from Fusarium sp. in different media. Compounds 1, 2, 6/7, 12, and 16 showed potent antifungal activity against Alternaria alternata, suggesting potential for developing agrochemicals.
Scientists used advanced sequencing techniques to assemble the genome of the coffee leaf rust fungus, a destructive global disease. This comprehensive genome can provide valuable insights for developing strategies to combat the disease and protect coffee crops.
Researchers extracted and analyzed the compounds in cascara pulp, a coffee by-product, and found high levels of antioxidants. This suggests that cascara pulp could be useful in preventing photoaging. Further research is needed to fully explore its potential benefits.
This review analyzed the therapeutic effects of natural products on obesity. Several natural products, including coffee, green tea, garlic, and others, showed anti-obesity effects. Further research is needed for clinical use.
A study used NMR spectroscopy and data analysis to differentiate coffee samples by origin and cultivation method. Successful differentiation of samples from Brazil and Ethiopia was achieved, but not for Colombian samples or organic vs. conventional samples.
Researchers analyzed the chemical profile of endophytic fungus Colletotrichum siamense from coffee plants and found potential compounds with pharmacological and antibacterial activity. This could be beneficial for the pharmaceutical and biotechnological industries.
Menthol and eugenol inhibit the growth and spore germination of toxigenic fungi in coffee beans. They can be used as preservatives to reduce financial losses and protect against fungal contamination during long-term storage.
This study evaluated the antitumor activity of extracts from three plant species: L., L., and L. Using HPLC-MS analysis, the phytochemical profile of the extracts was determined. In vitro screening revealed that L. extracts had the strongest anticancer and antioxidant effects. In vivo assessment using a mouse model showed that administration of L. and green coffee bean extracts reduced ascites cell viability and oxidative stress in tumor samples. Combining chemotherapy with L. or L. extracts induced lipid peroxidation in tumor cells, decreasing tumor viability. These findings suggest that L. extract, especially, has potential as an anticancer agent when used in combination with chemotherapy.
Comparing the chemical compositions and antioxidant properties of coffee flowers, leaves, and beans revealed significant differences. The coffee samples contained various chemicals belonging to 12 classes, with phenylpropanoids being the most dominant. Additionally, ACL had the highest DPPH radical scavenging capacity and acetylcholinesterase inhibitory activity while ACF had the highest ABTS radical scavenging activity. These findings suggest that coffee flowers and leaves may have potential value as novel foods in the future due to their antioxidant and acetylcholinesterase inhibitory activities.
Researchers explored the antiviral potential of herbal medicine for COVID-19 using microbial fuel cells. Ethanol extracts from air-dried leaves showed the highest bioenergy-stimulating capabilities and exhibited promising antioxidant and anti-inflammatory activities. Molecular docking analysis showed that chlorogenic acid had high binding affinity with RdRp of SARS-CoV-2. These findings suggest that leaves could be a potential medicinal herb for treating COVID-19.
