With regard to the importance of antioxidants in foods, cosmetics and pharmaceutics, there are several studies on natural resources for finding rich sources of antioxidants and their role in protecting the body against oxidative stress injuries. The purpose of this study was to investigate the antioxidant stability of arbutin and the Pyrus boissieriana buhse Leaf extract and their effects on li...

This study was aimed to optimize the extraction process for Salvia miltiorrhiza Bunge polysaccharide using response surface methodology The results showed that four operating parameters including microwave power, microwave time and the particle size had notable effects on the polysaccharide extraction of Salvia miltiorrhiza Bunge. The effects could be ranked in decreasing order of importance as...

Ethnomedicinal implies the usage of medicinal plants used by a group of people on account of their traditional knowledge and phytochemical means the individual chemical that plant contains. This review involves the ethnomedicinal and phytochemical perspectives of Pyrus communis Linn. In the “The Indian Materia Medica”, the common pear or gabbu gosha is considered as ‘Amritphale’ because of its ...

Pyrus magyarica was considered as a “superendemic” species of the Carpathian Basin for a long time; however, despite its presumed significance, doubts about its taxonomical status have been raised. the confusions originate from the invalidity of the description and the lack of type material. latter interpretations are not consistent and contradict the description of the species in the protologu...

Light Detection and Ranging (LiDAR) technology can be a valuable tool for describing and quantifying vegetation structure. However, because of their size, extraction of leaf geometries remains complicated. In this study, the intensity data produced by the Terrestrial Laser System (TLS) FARO LS880 is corrected for the distance effect and its relationship with the angle of incidence between the l...

The effects of storage and deep desiccation on structural changes of DNA in orthodox seeds are poorly characterized. In this study we analyzed the 5-methylcytosine (m(5)C) global content of DNA isolated from seeds of common pear (Pyrus communis L.) that had been subjected to extreme desiccation, and the seedlings derived from these seeds. Germination and seedling emergence tests were applied to...

two experiments were performed for in vitro establishment, proliferation and shoot growth in axillary bud explants of sebri pear cultivar. in the first experiment, the effect of different concentrations of iba(indole-3-butyric acid) on explants’ establishment was evaluated. in a second experiment, the influence of several combinations of pgrs (plant growth regulators)on shoot proliferation and ...
