Phytochemical Investigations on Chemical Constituents of Taraxacum bessarabicum (Hornem.) Hand.-Mazz. subsp. bessarabicum (Hornem.) Hand.-Mazz.
Plants of the genus Taraxacum Wigg., have long been used as medicinal herbs. A phytochemical investigation of the aerial parts of Taraxacum bessarabicum (Hornem.) Hand.-Mazz. subsp. bessarabicum (Hornem.) Hand.-Mazz. (Asteraceae) yielded two coumarins [esculetin (1), cichoriin (2)], three flavonoids [ luteolin (3), luteolin 7-O-β-D-glucoside (4), gossypetin (5)] and six phenolic acids and their...

متن کاملComparative Anatomy of Carpinus orientalis Mill. (Betulaceae) Populations in Iran.
Abstract. Natural populations of Carpinus orientalis Mill. Shrub lands occur mainly in high and middle altitudes of the Hyrcanian forests, N. Iran, particularly on steep rocks and forest outcrops. There are some discrepancies on the intra-specific delimitation of this important woody species. The aim of the current study was to examine the anatomical variation of stems and leaves of sixteen pop...
متن کاملSpatial Autocorrelation, Dispersal and the Maintenance of Source-Sink Populations
Populations may be regulated by both local density dependent factors and spatial variation in habitat quality I explore the in uence of spatial autocor relation in habitat quality on the survival of model populations Dispersal is modeled as Markov tran sitions between patches A nite rate of population increase was assigned to each patch Total habitat area and mean dispersal distance had strong ...
متن کاملInfluence of roadside pollution on the phylloplane microbial community of Alnus nepalensis (Betulaceae).
The North Eastern region of India is undergoing industrial development at a faster rate than expected. Roads form the main system of transportation and communication owing to the hilly topography of the region. Automobiles discharge a number of gaseous and trace metal contaminants. Human activities like stone grinding, road construction and sand milling also increase the atmospheric dust and he...
