Didar (Euphorbia tirucalli L.) from the family Euphorbiaceae, is a perennial succulent shrub with broad branched and round branches. Environmental factors are one of the most important factors affecting qualitative and quantitative traits in medicinal plants. In this study, Didar was studied in different habitats of Sistan and Baluchestan province in terms of some morphological, physiological, soil, and phytochemical characteristics. This study was conducted as a nested design and Duncan's least significant differences test at 5% level with completely randomized design with three replications using field survey and included some cities: 1- Hichan district from Nikshahr city (Kalat, Hesarak and Hashtik villages), 2- Rask city (Firoozabad, Jangal and Parood villages) and 3- Sarbaz city (Hit, Kishkour and Pirdan villages). The results showed that there was a significant difference between all the studied traits among cities and regions. In this study, morphological traits had the highest amount in Nikshahr city and the lowest height and number of branches belonged to Sarbaz city, indicating that the vegetative growth of this shrub decreases with increasing altitude. The soil studied in Nikshahr city regions was more favorable than other areas in terms of key elements such as phosphorus and potassium. The highest levels of 1- chlorophylls a and b and carotenoids and 2- proline and flavonoids were measured in spring and summer, respectively, but the highest amount of anthocyanin was observed in different cities variably. The highest amounts of 1- chlorophylls a and b and 2- carotenoids and anthocyanin were measured in Sarbaz and Rask cities, respectively. The highest amount and number of active ingredients of leachates of this plant were observed in summer.

Sarcocolla(Astragalus fasciculifolius Boiss.), belonging to Fabaceae family, is a medicinal plant distributed in the south of Sistan and Baluchestan province. Due to presence of compounds like saponins, flavonoids, and polysaccharides, it has an effective role in treating heart disease and cancer and eliminating chemotherapy and improving immunity. In this study, plant samples including eight A. fasciculifolius were collected from different habits in the province, and some phytochemical properties of root, leaves (total phenol, total flavonoid, and polysaccharide) and of flowers (total phenol, total flavonoid, and anthocyanin) were analyzed in the plant flower. The results of variance analysis showed a significant difference among different habitats (α>0.01). Phytochemical studies revealed significant amounts of phenolic compounds in the leaf with the highest rate recorded in Poshtkooh (14.62-32.55 mg GAE/g). In the root, the highest value was in Anjirok (20.39-53.84 mg GAE/g) and in the flower, the highest value was in BAirk (5.11-15.82 mg GAE/g), representing flavonoid compounds in the leaf in which the highest value was in Nahook (8.76-12.72 mg QE/g). Also, in root, the highest value was in Panjangosht (10 fingers) (0.25-1.03 mg QE/g). In the flower, the highest value was in Nahook (6.35-9.28 mg QE/g). In the polysaccharide compounds of the leaf, the highest value was in Anjirok (60.89-93.29 mg/g). In root, the highest values were in Pangangosht (94.33-209.38 mg/g) and anthocyanin of flower had the highest values in Pangangosht (36.34-77.58 mg/g). The results of this study represent the ability of different habitats of the province in producing valuable herbal compounds. Besides, because of its high levels of phenolic and polysaccharide compounds, this plant has a remarkable capability to be used in food and pharmaceutical industries.

Development and implementation of effective and useful programs for the rehabilitation, conservation and sustainable utilization of medicinal species is possible only by identifying plant and ecological characteristics. Astragalus fasciculifolius Bioss. belonging to the Fabaceae family, is a valuable medicinal species. This species plays an effective role in treatment of heart disease, inhibition of cancer cell growth, and eliminating the chemotherapy effects due to the presence of compounds such as saponins, flavonoids, and polysaccharides. In this study, the distribution map of this species was prepared using available resources, and then climatic characteristics, physical and chemical analysis of soil, different phenological stages, and associated plants in the region were recorded. The results of this study showed that this plant is distributed in the cities of Khash, Saravan, Soran and Mehrestan. According to the Demartonne method, the climate of this region is arid. The average annual precipitation, relative humidity, and an average temperature of these habitats are 52 mm, 20%, and 25°C, respectively. This species is distributed between approximately 1300 and 1500 m above sea level, on the slopes and mainly in the waterways, in the bed of seasonal rivers, and in all directions, especially the northern direction and the slope between 0 to 75%. The soil texture of habits is mainly sandy loam with the pH range of 6.73 to 8.28, EC range of 0.56 to 1.06 ds/m, and 30.64-50.62% lime. A. fasciculifolius is a drought tolerant species which is capable of growing under dry climatic conditions with an average annual rainfall of less than 30mm.
