Researchers developed a method to obtain high-purity monomers of hydroxyl-α-sanshool and hydroxyl-β-sanshool, which are important indicators of Zanthoxylum bungeanum quality. Significant variation in these compounds was found among different types of Z. bungeanum.
Study examines three endophytic fungi from Nigella sativa seeds, revealing potential antimicrobial properties against various pathogens. Molecular identification and chemical profiling of bioactive secondary metabolites support these findings. In-silico interactions also suggest effectiveness as antimicrobials.
Continuous cropping changes soil properties, microbial activity, and community characteristics, leading to increased organic carbon, phosphorus, nitrogen, and salt, while pH decreases. Bacterial diversity declines, but fungi diversity increases. Microbial community stability is disrupted. Bacterial community characteristics are influenced by phosphorus, potassium, carbon-nitrogen ratio, and soil respiration, while nitrogen, potassium, phosphorus, and soil respiration affect fungal community characteristics.
This study analyzed phenolic compounds in walnut leaves from northern Iraq. The compounds showed antibacterial and antioxidant properties, making them potential candidates for antioxidant drugs to treat oxidative stress-related diseases.
Researchers found that after 5 years of storage, aged Guang Chenpi, a Chinese herbal medicine, had increased flavonoid content and improved anti-spleen deficiency effects in mice. The study revealed that aged Guang Chenpi also regulated gut microbiota through specific flavonoids, highlighting the potential benefits of long storage time for herbal medicines.
Researchers discovered enzymes in a medicinal plant that produce bioactive compounds. They found that these enzymes are versatile and generated new compounds, including a potential antifungal agent.
Researchers discovered four new steroidal compounds and isolated twenty known compounds from Solanum lyratum Thunb plants. Some of these compounds showed significant cytotoxic effects against human colon and hepatoma cells, offering potential for cancer treatment. This study also provides chemical markers to help differentiate Solanum plants.
Scientists discovered and identified four flavonoids from maxim leaves. One of them showed moderate cytotoxicity against Lewis Lung cancer cells, while the others had weak cytotoxic effects.
