Introduction Elaeagnusangustifolia L. belongs to the genus Elaeagnus of the Elaeagnaceae family and is also called fragrant willow, cinnamon willow, silver willow, and Qi Lixiang; it is widely distributed in cold and arid Asia, temperate zones of
High-performance thin-layer chromatography, which is a quick qualitative and quantitative method, was used to determine 3 kinds of organic acids, namely, ellagic acid, gallic acid, and ferulic acid, in Elaeagnus angustifolia L. leaves originating from 10 regions in Xinjiang Uygur Autonomous Region and 7 different growth stages in Urumqi, China. The developing solvent was toluene‒ethyl formate‒formic acid (5:6.55:1.49), the temperature was 25 ± 1°C, the humidity was 10%, and the detection wavelength was 290 nm. The linear ranges of ellagic acid, gallic acid, and ferulic acid were 0.0564–0.6768, 0.1006–1.2072, and 0.1004–1.2048 μg, respectively, and the linear correlation coefficients were 0.9953, 0.9993, and 0.9970, respectively. The results showed good linear relationships. Precision analyses revealed a relative standard deviation (RSD) of <2.00%. The sample was stable within 24 h at room temperature at RSD ≤3.00%. The average recoveries of ellagic acid, gallic acid, and ferulic acid were 101.4%, 100.9%, and 100.2%, respectively. This method is reliable and can be used to determine three organic acids in the leaves of E. angustifolia L. from different regions and different growth stages.
Previous overviews of plant invasion in Hungary were based on local case studies and the authors’ experience. The MÉTA survey provided an opportunity to outline a more exact picture based on the survey of the whole country. This paper summarises the basic statistics related to plant invasion: cover of invaded area estimated for the country, each geographical region and each distinguished (semi-)natural habitat category, and cover of the selected 15 alien species in each habitat category.
