“…The chemical composition of Echinops is also somewhat specific, and some species in this genus have insecticidal, nematicidal, antifungal, bactericidal and also antiviral properities (i.e. Fokialakis et al 2006; Zhanget al 2009; Abdelnabby and Abdelrahman 2012; Tekwu et al 2012; Gemechu et al 2013; Liu et al 2013). Therefore, the inhabitants of Echinops flower heads might also be protected from some parasites and predators because of the chemical compounds in the plant.…”

Mature larva and pupa of Larinus vulpes (Olivier, 1807) (Curculionidae: Lixinae: Lixini) are morphologically described for the first time and compared with known larvae and pupae of other Larinus species. Very high counts of larval body setae (pronotum with more than 25 setae and postdorsum on meso- and metathorax and also on abdominal segments I–VII with more than 12 setae) are characteristic features of the nominotypical subgenus Larinus. The biology of the species was studied in Ukraine. Echinops ruthenicus and E. sphaerocephalus were identified as host plants of both larvae and adults of this weevil based on the present research in Ukraine, which shows probably oligophagous. Overwintering beetles emerged at the end of May or earlier, then feeding and mating on the host plants. The highest level of adult activity was observed at the end of June. Larvae were endophagous within the flower heads. In July and August, the larvae pupated within inflorescences in a pupation cell. Adults exited the cells at the end of August and did not hibernate on the host plants. Sometimes, larvae and imagines of a new generation were found outside the flower heads in chambers constructed on the stems.

“…There were many different reference to analyze the antituberculosis activity of plant extracts. In previous study, plants extract were considered active against M. tuberculosis if MIC was <100µg/mL (Borges-Argáez et al, 2007;Gautam et al, 2007;Okunade et al, 2004), <200µg/mL (Camacho-Corona et al, 2008;Tosun et al, 2004), < 1600µg/mL (Mohamad et al, 2011), ≤ 2048 µg/ml (Tekwu et al, 2012). In other paper, the antimicrobial activity of plant extracts was classified as significant (MIC ≤100µg/mL), moderate (100 < MIC < 625µg/mL), or weak (MIC > 625 µg/mL) (Kuete, 2010).…”

Tuberculosis (TB), in which caused by pathogenic bacteria, Mycobacterium tuberculosis, has become the major causes of death among all of infectious diseases. The increasing incidence of multidrug-resistant tuberculosis (MDR-TB) and extensively drug-resistant tuberculosis (XDR-TB ABSTRAK Tuberkulosis (TB) adalah penyakit yang disebabkan oleh infeksi Mycobacterium tuberculosis dan menjadi penyakit infeksi yang menyebabkan paling banyak kematian di dunia. Daruratnya penyakit TB dan meningkatnya kasus multidrug-resistant tuberculosis (MDR-TB) dan XDR-TB ini mendorong dilakukannya

ABSTRACT:Medicinal plants continue to be an important therapeutic aid for alleviating the ailments of human kind. The plant Dalbergia sissoo contains various chemical constituent with specific value in ethno-medicinal practices and has significance in the field of health care system. The main objective of this study involves the evaluation of anti-bacterial activity of D. sissoo leaves and barks extracts of chloroform, ethyl acetate, acetone and methanol. The assay was done by bioassay guided fractionation by disc diffusion method on both Staphylococcus aureus (gram-positive) and Escherichia coli (gram-negative) bacteria using Ampicillin for S. aureus and Norfloxacin for E. coli as positive control and DMSO (Dimethyl Sulphoxide) as a negative control. The anti-bacterial activity of methanol extracts of leaves was found to be more as compared to other extracts. S. aureus was found to be more susceptible to plant extracts than E. coli. Thus, the results obtained confirm the therapeutic potency of D. sissoo used in traditional medicine.
