(2012). Efficacy of Cryptolepis sanguinolenta root extract on slow-growing rifampicin resistant Mycobacterium tuberculosis. Journal of Medicinal Plant Research, 6(7), 1140- 1146.
New alkaloids from Cryptolepis sanguinolenta Neocryptolepine and biscryptolepine, two new alkaloids, were isolated from the root bark extract of the African medicinal plant, Cryptolepis sanguinolenta ... A Paulo,ET Gomes,PJ Houghton - 《Tetrahedron Letters》 被引量: 315发表: 1996年 ...
Purpose: To evaluate the paramunity induction potentials of crude methanol extract (CME) and methanol fractions (MF) of Cryptolepis sanguinolenta (CS) root (Fam. Periplocaceae). Method: A total of forty (40) albino rats were divided into two sets of four groups, with five anim...
We demonstrated previously that the aqueous root extract of Cryptolepis sanguinolenta (cryptolepis), with cryptolepine as the major constituent adversely affect reproduction and foetal development in mice. However, very little is known on the effect of prenatal exposure of cryptolepis on the post-...
In our biological screening of higher plants, an aqueous and an 80% EtOH extract from the root bark of CRYPTOLEPIS SANGUINOLENTA showed potent antibacterial, anticomplementary, and moderate antiviral activities, but no antifungal effect could be detected. Bioassay-guided fractionation of the 80% ...
Neocryptolepine and biscryptolepine, two new alkaloids, were isolated from the root bark extract of the African medicinal plant, Cryptolepis sanguinolenta (Lindl.) Schlechter (Periplocaceae), and their structures elucidated on the basis of spectral evidence. The 1 H and 13 C NMR assignments ...
The minimal inhibitory concentrations (MICs) of cryptolepine, ethanol and aqueous extracts of Cryptolepis sanguinolenta root were determined for 65 strains of Campylobacter jejuni, 41 strains of Campylobacter coli isolated from sporadic cases of gastroenteritis in Portugal and 86 strains of Vibrio ...
The aqueous root extract of the plant and its major alkaloid, cryptolepine (Figure 1) have diverse biological actions [1- 6]. We reported previously that cryptolepis, the aqueous root extract of the plant reduced sperm count in the caudal epididymis and fertility in male mice and inhibited ...
Neocryptolepine and biscryptolepine, two new alkaloids, were isolated from the root bark extract of the African medicinal plant, Cryptolepis sanguinolenta (Lindl.) Schlechter (Periplocaceae), and their structures elucidated on the basis of spectral evidence. The 1H and 13C NMR assignments of ...
Because cytotoxics can provoke adverse effects on developing foetuses, we studied the effect of the aqueous root extract of the plant (cryptolepis) on reproduction and foetal development in mice. Cryptolepis (62.5-1000 mg kg-1) reduced female fertility from 100% in the control group to 0% at...
