constituents of artemisia gmelinii weber ex stechm. from uttarakhand himalaya: a source of artemisia ketone.	the essential oils isolated from the aerial parts of two different populations of artemisia gmelinii growing in uttarakhand himalaya region were analysed by gas chromatography and gas chromatography/mass spectrometry (gc-ms) in order to determine the variation of concentration in their constituents. artemisia ketone was detected as a major constituent in both the populations i.e., niti valley and jhelum samples. niti oil was found to have considerably greater amounts of artemesia ketone (53.34%) ...	2012	23439844
Antioxidant activity-guided phytochemical investigation of Artemisia gmelinii Webb. ex Stechm.: Isolation and spectroscopic challenges of 3,5-O-dicaffeoyl (epi?) quinic acid and its ethyl ester.	Although Artemisia gmelinii Webb. ex Stechm. has long been used in south and south-east Asia to treat many kinds of inflammatory diseases, up until now its bioactivity-coupled phytochemical characterization has not been reported. We identified one fraction of the methanolic extract of A. gmelinii as a hit in our antioxidant screening (DPPH) campaign. In order to identify the active radical scavenger components of the extract, a DPPH-HPLC spiking assay was carried out. Out of six detected known c ...	2012	22079045
germinable soil seed banks and the restoration potential of abandoned cropland on the chinese hilly-gullied loess plateau.	poor vegetation cover is generally considered to be a major factor causing soil erosion on the loess plateau in china. it has been argued that tree planting restoration is ineffective, and natural re-vegetation is an alternative ecological solution for restoring abandoned cropland and controlling soil erosion. the aims of this study were to investigate the characteristics of soil seed banks and to assess the natural restoration potential of abandoned cropland in the hilly-gullied loess plateau. ...	2010	20694556
[photosynthetic characteristics of dominant plant species at different succession stages of vegetation on loess plateau].	according to the succession sequence of vegetation on ziwuling of loess plateau, the dominant species at different secondary succession stages, i. e., bothriochloa ischaemum, artemisia gmelinii, hippophae rhamnoides, sophara viciifolia, populus davidiana and quercus liaotungensis, were selected to measure the total n contents in their leaves and soil, and the parameters of leaf gas exchange, chlorophyll content and chlorophyll fluorescence. the results showed that with the succession of vegetati ...	2007	17763712
