Abstract
In the Yarlung Zangbo River Valley of the southeastern Tibetan Plateau, China (29°07'49.5"N, 92°41'11.0"E, 3256 m above sea level), we found an Ephedra saxatilis community in the xeric steppe with shrubland vegetation habitat of the broad alluvial plain of the river with soil having relatively higher water-soluble cation (Ca2+, 8.62; K+, 1.94; Mg2+, 2.38 mmol/100 g dry soil weight) and nitrogen (NO3-, 21.78; NH4+, 1.82 mmol/100 g dry soil weight) content. The ranges of ephedrine and pseudoephedrine in 13 E. saxatilis samples were as follows: ephedrine, not detected-3.03 of dry weight (%DW) and pseudoephedrine, not detected-1.36%DW. The 13 E. saxatilis plants collected in the study area showed intraspecific variability of ephedrine and pseudoephedrine with 6 samples containing ephedrine and pseudoephedrine, 6 samples containing only ephedrine, and 1 sample containing only pseudoephedrine.

Abstract
Dried terrestrial stems of Ephedra sinica are known as 'Ephedra herb.' The pharmacological effects are mainly related to two major ingredients, (-)-ephedrine and (+)-pseudoephedrine (total alkaloids which are defined in Japanese Pharmacopoeia, TA). In this study, in order to aid in cultivation and breeding, the stability of TA content and stem dry weight of 46 E. sinica genets was evaluated from the first year of transplantation to the sixth year. TA content and composition ratio of these genets were stable after the second year, and dry weight was stable after the fourth year. These traits showed high inter-genet variability but low annual variability for each genet. Additionally, rank correlation coefficients of each trait among the genets were high. There was no significant correlation between these traits. Furthermore, to assess the reproducibility of these traits in clones, we evaluated TA content and dry weight of three clonal lines with high TA contents. TA content and composition ratio of the clonal lines were also stable after the second year of transplantation, and dry weight of the clonal lines was also stable after the fourth year. Moreover, TA content and composition ratio in each clonal line were comparable with those of each original genet after the second year. These results suggested that ephedrine alkaloids content and dry weight of E. sinica plants are stable, and that these traits are highly reproducible in clones. Therefore, selection breeding of E. sinica using vegetative propagation can be effective for high and stable quality of Ephedra herb.

Abstract
In Uzbekistan, Ephedra distachya L., E. equisetina Bunge, E. foliata Boiss. ex C. A. Mey., E. lomatolepis Schrenk, and E. strobilacea Bunge show species specificity for habitat environments and physical and chemical characteristics of habitat soils. Furthermore, the relationship between soil characteristics and ephedrine and pseudoephedrine contents was examined. E. distachya was found growing from 80 to 200 m above sea level (a.s.l) in the Plateau Ustyurt on the desert steppe of cliffs on soil having relatively higher loss on ignition (19.8-33.8%) and water-soluble cations (Ca2+, 5.14-133.13; Mg2+, 0.85-3.18; and Na+, 2.27-8.33 mmol/100 g dry soil weight) than for other Ephedra habitats. E. strobilacea was found growing on the flat sandy Kyzylkum desert at 94 m a.s.l. and had habitat soil that was the driest with the lowest loss on ignition (2.9%) and highest Na+ (9.05 mmol/100 g dry soil weight) of all the Ephedra habitat soils. On dry steppe from 1054 to 1819 m a.s.l., E. foliata, E. lomatolepis, and E. equisetina formed not only a single community but also a complex community on constantly collapsing sandy gravel slope with relatively higher Ca2+ (3.40-17.44 mmol/100 g dry soil weight) soil content. Notably, E. equisetina grew on the dry steppe of constantly collapsing sandy gravel slopes, in rocky areas, on sandy gravel floodplains of rivers, and on stable humus soil at the base of coniferous trees in a wide range of habitats from dry steppe to coniferous forest zones at altitudes ranging from 1392 to 1819 m a.s.l., as reflected in the greater variability than for other Ephedra habitats in the parameters of loss on ignition (1.4-34.8%), pH (7.1-9.6), NO3- (0.08-35.17 mmol/100 g dry soil weight), Ca2+ (0.24-17.44 mmol/100 g dry soil weight), Mg2+ (not detected-1.25 mmol/100 g dry soil weight), and Na+ (0.13-5.19 mmol/100 g dry soil weight). Ephedrine alkaloids were not detectable in E. strobilacea, E. foliata, and E. lomatolepis. Almost all E. distachya contained only pseudoephedrine (1.25-1.59% of dry weight, %DW), while E. equisetina contained from 1.31 to 2.05%DW ephedrine and from 1.29 to 2.80%DW pseudoephedrine. Ephedrine and pseudoephedrine in E. equisetina showed a statistically significant negative correlation with soil Cl- and Mg2+, respectively.
