Antibacterial, anti-inflammatory and anti-allergic activities of standardised pomegranate rind extract
The potential use of standardised pomegranate rind extract as a nutraceutical for antibacterial, anti-inflammatory and anti-allergic proposes is supported.
Plumbagin production by root cultures of Plumbago rosea
Root cultures of Plumbago rosea Linn. were established from young leaf explants on solid Gamborg's B5 (B5) medium supplemented with the combination of α-naphthalene acetic acid (NAA) and kinetin in
Effects of lawsone methyl ether mouthwash on oral Candida in HIV-infected subjects and subjects with denture stomatitis.
Use of LME mouthwash for 2 weeks neither led to antifungal drug resistance nor significant changes in genotype of oral Candida, thus, LME may be an alternative mouthwash in prophylaxis of oral candidiasis among those at risk of developing the disease.
Topical anti-inflammatory and analgesic activities of standardized pomegranate rind extract in comparison with its marker compound ellagic acid in vivo.
The results clearly demonstrated that SPRE is a promising phytomedicine that could find use in the treatment of inflammatory diseases.
Effects of rhinacanthins from Rhinacanthus nasutus on nitric oxide, prostaglandin E2 and tumor necrosis factor-alpha releases using RAW264.7 macrophage cells.
Three naphthoquinone derivatives, rhinacanthin-C, -D and -N, isolated from the leaves of Rhinacanthus nasutus extract possessed very potent anti-inflammatory activity against lipopolysaccharide (LPS)-induced nitric oxide release with IC(50) values of 1.8, 6.2 and 3.0 microM, respectively.
Comparative antiulcer effect of bisdemethoxycurcumin and curcumin in a gastric ulcer model system.
Results indicated that bisdemethoxycurcumin directly accelerates gastric ulcer healing with potency equal to curcumin, which might be due to its properties of decreasing gastric acid secretion and enhancing the mucosal defensive mechanism through suppression of iNOS-mediated inflammation.
Antimicrobial activity and stability of rhinacanthins-rich Rhinacanthus nasutus extract.
Assessment of antimicrobial activities of the RRn extract as well as rhinacanthin-C against Streptococcus mutans, Propionibacterium acnes, Helicobacter pylori, Staphylococcus aureus, S. epidermidis, P. acnes and Candida albicans found that it exhibited potent bactericidal activity against S. mutans and potent bacteriostatic activity against others.
Comparison of antimicrobial activities of naphthoquinones from Impatiens balsamina
Three main naphthoquinones in the leaf extracts of Impatiens balsamina L. (Balsaminaceae) were evaluated by determination of minimal inhibitory concentrations (MICs) and minimal bactericidal or fungicidal concentrations (MBCs or MFCs) using a modified agar dilution method.
RP-HPLC analysis of rhinacanthins in Rhinacanthus nasutus: validation and application for the preparation of rhinacanthin high-yielding extract.
It was found that ethyl acetate was an appropriate solvent for rhinacanthin extraction and the antifungal activities of HRn against Trichophyton rubrum, T. mentagrophytes, and Microsporum gypseum were improved.
Increased production of plumbagin in Plumbago indica root cultures by biotic and abiotic elicitors
Chitosan (150 mg l−1), l-alanine (5 mM), and 1-naphthol (50 µM) were the best elicitors to enhance plumbagin production in P. indica root cultures.
