Leave a Reply Cancel reply Enter your comment here Human macrophages THP-1 cells were used to assess the cytotoxic effects of bioactive compounds using propidium iodide staining.
To the best of our knowledge, we provide the first experimental evidence demonstrating its antimicrobial activities against bacteria, fungi, and a parasite. Mosquito flower or Mexican lopezia, Lopezia racemosa. Fill in your details below or click an icon to log in: Yet, other compounds present in the extracts may exert different biological activities as observed in different studies.
Archived Entry Post Date: August 25, at racenosa Furthermore, some species produce significant amount of tocopherols, compounds that have been used as chemotaxonomic markers within the Onagraceae family [ 16 ]. Among flavonoids, isolated compounds from this family include flavonols, glycoflavones, flavones, and chalcones [ 1314 racmeosa. Please enter your password Forgotten your password? However, extracts from different members of the Onagraceae family, such as Epilobium and Ludwigiahave broad activity against Gram-positive and -negative bacteria [ 19 — 22 ].
We’ve sent an email to Please follow the instructions to reset your password. Table of Contents Alerts. Cytotoxicity was evaluated with human-derived macrophages THP-1 cells. For fungal strains, Sabouraud broth Becton and Dickinson was used. DMSO and untreated inocula were used as negative controls, while amphotericin B was used as a positive control. The anti-inflammatory process was evaluated by measuring the secretion of IL-6 into the supernatant.
Spores of Aspergillus fumigatus and Trichophyton rubrum were carefully harvested and stored as published [ 17 ].
Untreated parasites and DMSO were used as negative controls. For Candida albicans and Cryptococcus neoformansthe same protocol used for bacterial strains was followed, but with Sabouraud broth. Bacterial stocks were maintained on racemoza same medium supplemented with 1. Lopezia racemosa, Mosquito flower Mosquito Flower Lopezia racemosa native to Mexico flowering in summer Lopezia racemosa inflorescence Lopezia racemosa Mexican lopezia, Lopezia racemosa.
The Scientific World Journal
Values are expressed as percentage of inflammation after normalization to LPS. If is associated with an Alamy account you’ll receive an email with instructions on how to reset your password. Continue Cancel Send email OK. Extracts and fractions obtained from L.
Moreover, a single fraction HF 11—14b showed significant anti-inflammatory activity. Various extracts and fractions showed antibacterial, antifungal, antiparasitic, and anti-inflammatory activities. The same macrophage cell line lopezis used to investigate the cytotoxicity of the compounds. Several studies have also shown that extracts from E. There are seven species known in these countries, all fairly similar in growth and requirements.
Can you sell its seeds or roots of Racemosa? Diverse studies have demonstrated that different members of the Onagraceae family have selective anti-inflammatory activity in animal models [ 781527 ] and cytotoxic activities against several tumor cell racemosz [ 111228 — 30 ].

Lopezia racemosa, Mosquito flower Mosquito Flower Lopezia racemosa native to Mexico flowering in summer Lopezia, Mosquito Flower Lopezia racemosaflowers Mosquito flower or pink brush, Lopezia racemosa, native to Mexico. Leishmania donovani promastigotes were cultured as published [ 17 ].
Lopezia – Wikipedia
After an illustration by S. It is very easy to grow from seed if sown in February to March. In the case of filamentous fungi, bioactivities were tested using harvested spores.
Pinging is currently not allowed. Propidium iodide PI was used to evaluate membrane damage [ 18 ]. Sorry for the delay — i have been away.
In summary, we have demonstrated for the first time that extracts of the aerial parts of L. Extracts and fractions were tested against a panel of nine bacterial and four fungal species. Most of the genera studied possess mainly flavonols, which include myricetin, quercetin, kaempferol, and remarkable amounts of various phenolic acids [ 6715 ].
To the best of our knowledge, this is the first study reporting the biological activities of L. The minimal inhibitory concentrations MICs were determined when no turbidity in the well was observed. Phytochemical analyses have shown that oenothein B is the main tannin isolated from Epilobium and Oenotherafollowed by other flavonoids such as myricetin- quercetin- and kaempferol-glycosides [ 6 — 8 ].
A microdilution assay was used to determine the antimicrobial activities in a well plate and according to published protocols [ 17 ].
