Weinmannia marquesana F. Br. var. angustifolia Lorence & W. L. Wagner, var. nov., a new variety with narrow, simple leaves endemic to Tahuata, Marquesas Islands (French Polynesia) is described and its affinities and conservation status are discussed. It is similar to the other two varieties of this species by having simple leaves, but this new variety has much narrower leaf blades, and it resem...

UNLABELLED PREMISE OF THE STUDY Microsatellite markers were developed for the plant species Elaeagnus angustifolia to assist in future investigations of genetic variability in its native and invasive ranges and the precise origins of the United States/Canada invasion. • METHODS AND RESULTS Eleven polymorphic microsatellite markers were developed. The number of alleles observed for each loc...

The pervasive difficulties encountered with studying Galactia in the eastern USA necessitate additional typifications to stabilize the taxonomy. Galactia purshii is lectotypified here as the earliest available but overlooked name for a fairly common species of the Atlantic Coast and peninsular Florida. Galactia volubilis is epitypified here since the characterization of the species has been lim...

inhibitory effects of lavandula angustifolia and zataria multiflora essential oils were evaluated on reproduction and f1 progeny production of callosobruchus maculatus. insect’s culture and bioassays were conducted at 29 ±1ºc, 60±5% rh and dark condition. essential oils were taken by hydrodistilation. the results indicated that there was a negative and significant linear relationship between re...

Two new steroidal saponins, named drangustosides A-B (1-2), together with eight known compounds were isolated and characterized from the MeOH extract of Dracaena angustifolia Roxb. The structures of compounds were assigned based on 1D and 2D NMR spectroscopic analyses, including HMQC, HMBC, and NOESY. Compounds 1 and 2 showed anti-inflammatory activity by superoxide generation and elastase rele...

The National Toxicology Program (NTP) has announced that it will design and initiate studies to identify and characterize possible adverse health effects that may be associated with prolonged use or higher doses of some of the most popular medicinal herbs, including Ginkgo biloba, Echinacea angustifolia, and Panax quinquefolius (American ginseng). The NTP studies a large variety of substances t...

Culturas do fungo Fusarium graminearum sob agitação na presença do diterpeno ácido cupréssico [ácido 13-hidróxi-(17),14-labdadien-19-óico], obtido de Araucarea angustifolia elegans, produziram quatro derivados diterpênicos hidroxilados os quais foram identificados por métodos químicos e físicos como sendo os ácidos 3 ,13-diidróxi-8(17),14-labdadien-19-óico, 7 ,13-diidróxi-8(17),14labdadien-19-ó...

ABSTRACT: Chemical composition of Lavandula angustifolia was studied by solvent free microwave extraction (SFME) and hydrodistillation (HD) methods. 1, 8-cineole (42.7% and 37.9%), Camphor (26.1% and 21.3%) and Borneol (31.2% and 21.6%) were the major compounds that obtained by SFME and hydrodistillation, respectively. The antibacterial activity of extracted oils was investigated against Gram-p...

Multiple shoots were obtained from nodal segments of mature trees of Elaeagnus angustifolia L. cultured on MS medium (Murashige and Skoog 1962) supplemented with 0, 0.88 or 2.22 micro M N(6)-benzyladenine. When nodal segments taken from the in vitro proliferated shoots were cultured under the same conditions, additional multiple shoots were obtained. Rooting of the in vitro propagated shoots wa...
