“…The present antioxidant activity results of in vitro germinated seedlings of R. vesicarius L. were in agreement with Nishina et al (1991), Demirezer et al (2001), Al-Ismail et al (2006), Özen (2010) and Li and Liu (2009). They investigated different extracts of roots of R. japonicus and R. patientia, leaves of R. pulcher and R. acetosella and whole plant parts of R. dentatus, respectively.…”

The present work has been carried out to investigate both the antibacterial and antioxidant activities of seedlings grown in vitro and in vivo. Only ethanol extract of in vitro germinated seedlings on solidified Murashige and Skoog (MS) hormone free medium, had antibacterial activity. Activity was high in case of Pseudomonas aeruginosa, Escherichia coli and Streptococcus pneumoniae (inhibition zones = 55.00 ± 0.00, 55.00 ± 0.00 and 26.25 ± 1.58 mm; activity index = 4.15, 1.67 and 0.48, respectively). The effect was moderate in case of Staphylococcus aureus (inhibition zone = 15.75 ± 1.58 mm, activity index = 1.67). The extract had no effect against Klebsiella pneumoniae and Streptococcus pyogenes. Total antioxidant activity studies (GAE s in ppm) showed that 20 days old in vivo grown seedlings were highest in total antioxidants (1810.00 ± 60.12), followed by 30 days old in vivo grown seedlings (1133.13 ± 55.35). Results of 2,2-diphenyl-1-picrylhydrazyl (DPPH) scavenging activity showed that the least IC 50 in mg/ml was obtained using 30 days old in vivo grown seedlings extract (IC 50 = 1.16 ± 0.02), followed by 20 days old in vivo grown seedlings extract (IC 50 = 1.26 ± 0.02). The study shows the possibility of producing biological activity from early developmental growth stages of Rumex vesicarius.

“…As a traditional medicine plant, it was shown to have some pharmacological activities, including anti-inflammatory, antioxidant (Wegiera et al 2007), anti-tumor, antibacterial, antiviral, and anti-fungal properties (Taylor et al 1996;Demirezer et al 2001;Lee et al 2005). Meanwhile, its leaves are widely used in sauces and salads (Ahmad et al 2006).…”

Rumex acetosa , known as sheep’s sorrel, red sorrel, sour weed, and field sorrel, is a species of flowering plant in the buckwheat family Polygonaceae. In this study, the complete chloroplast (cp) genome of R. acetosa (Rumiceae) was determined through Illumina sequencing method. The complete chloroplast genome of R. acetosa was 160,269 bp in length and contained a pair of IR regions (30,503 bp) separated by a small single copy region (13,128 bp) and a large single copy region (86,135 bp). This cp genome is encoded with 129 genes including 83 protein-coding genes, 36 tRNA genes, and 8 ribosomal RNA genes. The overall GC content of R. acetosa cp genome is 37.2%. By phylogenetic analysis using Bayesian method, R. acetosa showed the closest relationship with other 2 Rumiceae species, Rheum palmatum and Oxyria sinensis .

“…The anticarcinogenic and antimutagenic potentials of tannins may be related to their antioxidative properties important in preventing cellular oxidative damage, including lipid peroxidation (Haslam, 1998). Okamura et al (1993), Bors et al (2000), Demirezer et al (2001) and Velázquez et al (2003) demonstrated the antioxidant activity of extracts and tannins isolated from red wine, Eucalyptus rostrata Schltdl., Camellia sinensis (L.) Kuntze, Rumex patientia L., Aristolochia giberi Hook, Schinus weinmannifolia Engler, and Piper fulvescens DC.…”
