Zataria multiflora Boiss. is one of the valuable and endangered medicinal plants used in food and medicine industries. A study was conducted in a completely randomized design with three replications in four habitats of Isfahan, Fars, Yazd and Hormozgan provinces to investigate some of the mineral elements of Zataria multiflora Boiss. (Shirazian thyme) and also for comparing the accumulation of heavy metals in some natural habitats of the country. The mineral elements of this medicinal plant including micronutrients and a number of essential and high-consumption elements such as iron, zinc, manganese, copper, magnesium, sodium, calcium, potassium and a number of metals such as chromium, cobalt, silicon, lead, arsenic, nickel, cadmium, vanadium, totally 17 elements, were measured by using an inductively coupled plasma measuring apparatus (ICP-OES). The results of analysis of variance showed a significant difference among habitats for all elements except arsenic, cadmium and mercury (P <0.01). The three mentioned metals were not detected by the ICP apparatus and were, therefore, considered negligible. The results of this research also showed that the habitat affected the qualitative attributes of the study species. The plants grown in Yazd had the maximum amount of sodium, magnesium, iron and the minimum amount of calcium and cobalt, while the plants grown in Isfahan had maximum amount of zinc, manganese, copper, potassium and minimum amount of sodium and magnesium, indicating the significant effect of habitat on the qualitative attributes on this medicinal plant. Comparison of the amount of heavy elements accumulated in collected plants with permissible limit, reported by the World Health Organization, indicated that these elements were not toxic. This research was aimed to study the possibility of introducing ionomic indicators for identification of Zataria multiflora Boiss. populations as well as comparison of product health among different habitats.

Jujube (Ziziphus jujube Mill.) is a valuable medicinal tree, distributed in Iran. The fruit of this plant is used in food and pharmaceutical industries. In this study, some pytochemical, morphological and minerals of 23 Jujube (J1-J23), located in the Gazeroon research station in Qom province, were analyzed. Total soluble carbohydrate (TSC) of samples varied from 5.54 to 23.36%. The highest and lowest content of TSS was obtained from J1 (36.13%) and J22 (16.1%) ecotypes, respectively. J7 ecotype had the highest amount of total acidity (TA) (3.31%). The protein amount of samples was between 5.6 (J19) and 13.5% (J7). The highest amount of N, P, K, Fe, Zn, Cu and Mn was obtained from J8 (2.16%), J8 (0.153%), J17 (1.25%), J3 (28.91 ppm), J4 (41.12 ppm), J3 (50.27 ppm), J1 (80.23 ppm) and J8 (0.35 ppm) ecotypes, respectively. Based on dendrogram from cluster analysis, the samples were divided into eight groups. The lack of consistency in cluster analysis could be due to the differences in genetic factors. Pearson’s coefficients showed total soluble carbohydrate had significant correlation with TSS. In addition, correlation between fruit diameter with fruit length and length/diameter of fruit were significantly positive. Other chemical compositions do not show correlation with fruit morphological traits.

Dog rose (Rosa canina L.) is considered as one of the most important medicinal plants, which contain valuable medicinal and nutritional compounds in its fruits. In order to determine total phenolic, soluble carbohydrates, carotenoid contents and minerals in dog rose fruits collected from five different ecological regions in south-west of Iran (Kiar and Gerd Bishe in Charmahal & Bakhtiari, Yasuj and Meymand in Kohgiluye & Boyer Ahmad and Semirom in Isfahan), an evaluation was carried out during 2006-2007. Total phenolic contents, total soluble carbohydrates and total carotenoids varied from 83.13-94.14 mg GAE/g DW, 13.34–17.14% and 408.36–495 µg/g FW, respectively. The N, P, K, Mg, Ca, Fe, Zn and Mn values of fruit samples differed from 0.73-1.15%, 2816–4278 ppm, 2036–3325 ppm, 689–1092 ppm, 821–1243 ppm, 34–52 ppm, 15–29 ppm and 23–43 ppm, respectively. This study showed that fruits of dog rose are a rich source of phenolic contents, soluble carbohydrates, carotenoids and minerals. In this study, content of active substances affected by climatic factors of case studies was investigated.
