Pharmacognostic evaluation of leaf and root bark of Holoptelea integrifolia Roxb.

Asian Pacific Journal of Tropical Biomedicine 2012年第3期2卷 169-175页

作者： Dinesh Kumar Karunesh Kumar Sunil Kumar Tarun Kumar Ajay Kumar Om Prakash Institute of Pharmaceutical Sciences Kurukshetra University

Objective:To evaluate the pharmacognostic characters of an important medicinal plant, Holoptelcu integrifolia(***) ***:The pharmacognostic studies were carried out in terms of organoleptic,microscopic,macroscopic and fluorescence ***: The characteristic microscopic features of leaves were observed as trichomes,multicellular trichomes,xylem cells,phloem cells,collenchyma,vascular bundles,spongy parenchyma and palisade *** characteristic microscopic features of root bark included cork cambium, primary cortex,phloem fibers,medullary rays,endodermis,pericycle and lignified fibers in the transverse section and longitudinal *** characteristic microscopy of root bark powder showed the presence of cortex cells,sieve tubes,calcium oxalate crystals and lignified fibers. Macroscopic study showed that leaf shape-oval,apex-acute,base-cordate and leaf margin was entire with glabrous surface,bitter taste and characteristic *** morphological features of root bark showed deep fissured,rough and firm surface with rhitydome and the periderm parallel to ***:Various pharmacognostic characters observed in this study help in the identification and standardization of ***.

Objective:To evaluate the ovicidal and larvicidal activities of aqueous and ethanolic extracts of leaves of Dichrocephala integrifolia(***)against the eggs(fresh and embryonnated),the first and second larval stages of Heligmosomoides *** order to verify if this medicinal plant possesses active compounds capable of inhibiting the embryonation and hatching of eggs or to induce the mortality of larvae(L1 and L2).Methods:Dried extracts were diluted in distilled water to obtain five different concentrations:625,1 250,2500,3750 and 5000μg/*** eggs obtained from artificially infected mice feces were exposed to these different concentrations for 48 *** of contact for embryonated eggs was 6 h while L1 and L2 larvae were exposed for 24 *** water(placebo)and 1.5%DMSO were used as negative ***:Distilled water,and1.5%DMSO had no effect on embryonation,hatching and larval *** extracts of *** showed a weak activity against all stages of the parasite at all concentrations *** the contrary,the ethanolic extract of *** inhibited the embryonation of 87.5%of fresh eggs,the hatching of 81.1%of embryonated eggs and induced the mortality of 98.1%and 98%of L1 and L2 larvae respectively at 5000μg/***:The results of the present study indicate that the ethanolic extracts of *** contained compounds with ovicidal and larvicidal *** spite of these results,in vivo tests,studies on toxicity and mechanism of action of active compounds are also needed to validate the utilisation of this medicinal plant by population of Dschang-Cameroon to treat gastro-intestinal parasites.

Macadamia from the family Proteaceae is a plant native to Australia and has long been favoured by people for its crispy and high nutritional and medicinal ***,the genome of GUIRE 1(GR1),a highly heterozygous superior cultivar of macadamia nut,was sequenced and assembled using nanopore sequencing,and a 807-Mb genome(contig N50,1.9 Mb;scaffold N50,54.70 Mb)and 14 chromosomes were obtained.A total of 453 Mb(about 55.95%)repetitive sequences and 37,657 protein-coding genes were obtained by gene annotation and homologous protein *** diverged from Nelumbonaceae nearly 115.37 million years ago and from Rubiaceae about 140 million years ago.A genome-wide duplication(WGD)event occurred in macadamia 41 million years ago based on the WGD *** functional enrichment analysis of ***-specific gene families revealed their roles in signal transduction,protein phosphorylation,protein binding,and defense ***,a highly heterozygous genome of *** was unlocked to provide a database for breeding and molecular mechanism research.
