Authentication and identification markers for medicinal plants: I Aristolochia bracteolata

<p class="abstract"><strong>Background:</strong> Aristolochiaceae is a unique plant family that contains aristolochic acids (AAs), with around 600 species.</p><p class="abstract"><strong>Methods:</strong> The entire chloroplast genome of <em>Aristolochia bracteolata</em> was sequenced in this work, and fourteen chloroplast (cp) genomes were retrieved from the NCBI database. </p><p class="abstract"><strong>Results:</strong> We also analyzed six types of microsatellite markers among these species and found some different markers for each species. A molecular phylogeny based on 7 barcode regions i.e. <em>matK,</em> <em>atpF</em> to <em>atpH</em>, <em>psbK</em> to <em>psbI</em>, <em>rbcL, rpoB, rpoC2</em> and <em>rpoC1</em> is proposed for <em>Aristolochia </em>and 16 species from Piperales, <em>Arabidopsis thaliana</em> is taken as an outgroup. Phylogenetic relationships using concatenated protein-coding genes from Chloroplast genomes of Piperales using the maximum likelihood method is also discussed.</p><p class="abstract"><strong>Conclusions:</strong> In the present study we are providing some unique markers<strong> </strong>and phylogenetic relationships among Piperales members which will help in identification, authentication, to prevent adulteration and further investigation of these medicinal plants.</p>

Antioxidant activity of some Sudanese medicinal plant methanolic extracts

Traditional medicines play a very important role in the health care system in Sudan, Cadaba glandulosa , Aristolochia bracteolata , Boscia senegalensis and Nymphaea lotus are used in folkloric medicine to remedy some diseases. The methanolic extracts were used to evaluate antioxidant activity to the plants which were mentioned above. B senglensis was shown high activity equal to 87+1, while N. lotus was represented 82+2. Also A. bracteolate and C. glandulosa exhibited moderate values (54+0.03 and 41+0.04 respectively).

Phytochemical and In-vitro Antioxidants Potential of Aristolochia Bracteolata Root Extract

The study investigated the phytochemical and in-vitro antioxidants potential of Aristolochia bracteolata root extracts. Qualitative and quantitative phytochemical analysis of the plant extract and fractions were carried out. The total antioxidant and free radical scavenging activity of extract and fractions were measured by 1, 1-diphenyl-2-picryl-hydrazyl, FRAP and TBARS methods. Results obtained showed that total saponins (10.10 ± 0.05d) as well as antioxidant activity were found to be significantly (p< 0.05) higher in the methanol extract compared to the fractions. From the findings above, Aristolochia bracteolata root contains bioactive phytochemicals that might be helpful in preventing or slowing the progress of various oxidative stresses.
