Article Synopsis
- The study investigates the insecticidal properties of essential oils from Cymbopogon citratus and Hyptis suaveolens against Anopheles gambiae mosquitoes, which are resistant to synthetic insecticides.
- The oils were extracted, analyzed for their chemical composition, and tested for efficacy, revealing that co-distilled oil showed higher insecticidal activity compared to mixtures of pure oils.
- Results indicated that co-distilled essential oil primarily contains piperitone and 1,8-cineole, leading to significant mortality rates in mosquito populations, particularly in insecticide-resistant strains.
Ethnopharmacological Relevance: Knowledge of the high-sale medicinal plants and their authentication are essential parameters to ensure the safety of people using herbal medicine and to plan the safeguarding of medicinal species threatened with extinction.
Aims: The present study, carried out in Lubumbashi, Democratic Republic of Congo, aimed to geolocate medicinal plant sales points, list the best-selling species, and authenticate samples of the most popular species on the market.
Methods: A survey was conducted among the medicinal plant sellers in Lubumbashi's markets and other public spaces, to identify the best-selling species.
Recent findings from the World Heart Federation (WHF) reported a significant increase in cardiovascular disease (CVD)-related deaths, highlighting the urgent need for effective prevention strategies. Atherosclerosis, a key precursor to CVD, involves the accumulation of low-density lipoprotein (LDL) and its oxidation within the endothelium, leading to inflammation and foam cell formation. Ginger extracts, known for their antioxidative and anti-inflammatory properties, show promise in preventing CVD initiation by inhibiting LDL oxidation and reducing foam cell formation.

- Guava fruits, commonly used in Malagasy traditional medicine, were tested for their antibacterial properties against the bacteria PAO1, focusing on their ability to combat gastrointestinal infections.
- While three organic extracts showed no direct antibacterial effects, the hexane and dichloromethane extracts demonstrated significant anti-biofilm properties and disrupted bacterial movement.
- Lycopene and β-sitosterol-β-D-glucoside were identified as major anti-biofilm compounds in the dichloromethane extract, enhancing the effectiveness of tobramycin against biofilm-encapsulated PAO1.
