Mineral Elements and Their ICP-MS Validation in Crepidium acuminatum (D.Don) Szlach.- An Ashtavarga Plant

Abstract Ionomics measures elemental concentrations in biological organisms and provides a snapshot of physiology under different conditions. In this study, we evaluate genetic variation of the ionome in outbred, perennial switchgrass in three environments across the species’ native range, and explore patterns of genotype-by-environment interactions. We grew 725 clonally replicated genotypes of a large full sib family from a four-way linkage mapping population, created from deeply diverged upland and lowland switchgrass ecotypes, at three common gardens. Concentrations of 18 mineral elements were determined in whole post-anthesis tillers using ion coupled plasma mass spectrometry (ICP-MS). These measurements were used to identify quantitative trait loci (QTL) with and without QTL-by-environment interactions (QTLxE) using a multi-environment QTL mapping approach. We found that element concentrations varied significantly both within and between switchgrass ecotypes, and GxE was present at both the trait and QTL level. Concentrations of 14 of the 18 elements were under some genetic control, and 77 QTL were detected for these elements. 74% of QTL colocalized multiple elements, half of QTL exhibited significant QTLxE, and roughly equal numbers of QTL had significant differences in magnitude and sign of their effects across environments. The switchgrass ionome is under moderate genetic control and by loci with highly variable effects across environments.

The feasibility of combining elemental fingerprints and chemical pattern recognition methods for authentication of the geographical origins of a Chinese herb, Gastrodia elata BI. (GE), was studied in this paper. A total of 210 GE samples were collected from 7 different producing areas. The levels of 15 mineral elements in GE, including Zn, Cd, Co, Cr, Cu, Ca, Mg, Mn, Mo, Ni, Pb, Sr, Fe, Na, and K, were determined using inductively coupled plasma mass spectrometry (ICP-MS). Using the autoscaled data of elemental fingerprints and partial least-squares discriminant analysis (PLSDA), two chemometrics strategies for multiclass classifications, One-Versus-Rest (OVR) and One-Versus-One (OVO), were studied and compared in discrimination of GE geographical origins. As a result, OVR-PLSDA and OVO-PLSDA could achieve the classification accuracy of 0.672 and 0.925, respectively. The results indicate that mineral elemental fingerprints coupled with chemometrics can provide a useful alternative method for simultaneous discrimination of multiple GE geographical origins.

Elemental Data

Abstract An analytical method based on inductively coupled plasma/mass spectrometry (ICP/MS) was developed for the determination of 28 mineral elements (Cr, Mn, Co, Ni, Cu, Zn, Ga, Sr, Cd, Ag, Ba, Pb, Bi Y, La, Ce, Nd, Pr, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb, and Lu) in Indian opium samples. The detection limits were found to be in the range of 0.0008–0.45 ng/mL. The recoveries of spiked samples for each element were found to be in the range of 83–106%, with a precision of less than 9%. A total of 124 opium samples from India were analyzed for the distribution pattern of the 28 mineral elements. Quantitative elemental data were subjected to chemometric analysis in order to determine an optimal classifier to evaluate the source of Indian opium. The study indicated that mineral elements might not be the suitable discriminators for the discrimination of licit opium-growing divisions of India. However, the methodology developed and the analytical data on elemental profile may find important forensic application in discriminating Indian opium with that of licit and illicit opium originating from different geographical regions of world.

Abstract Black shales are easily exposed duo to human activities such as mining, road construction, and shale gas development, which results in several environmental issues including heavy metals (HMs) pollution, soil erosion and the destruction of vegetation. Moss are widely used to monitor metal pollution in the atmosphere, but few studies on the distribution and dispersion of HMs in the rock – soil – moss system are available. Here, mosses (P. flexuosa Harv), growing soils, and corresponding parent rocks were collected from black shale areas. After appropriate pretreatment, samples were analyzed for multiple elements concentration by ICP-AES and ICP-MS. The results show that black shales parent rocks have elevated HMs concentration, and act as a source of multiple metals. Soil significantly inherit and accumulate heavy metals released from black shale. Significant positive correlations between HMs in P. flexuosa Harv and the growing soils indicate that HMs are mainly originating from geological source rather than atmospheric deposition. Compared with other elements, only the transfer factor (TF) of Cd is greater than 1, the normal functioning of mineral elements (K and Zn) absorption and transportation may contribute to its high tolerance to Cd. Finally, both the BCF and TF for most HMs in P. flexuosa Harv are less than 1, indicated that it has a tolerance and exclusion mechanism for these metals. Therefore, the luxuriant and spontaneous growth of P. flexuosa Harv could be used as a phytostabilization pioneer plant in the black shale outcrop where vascular plants are rare.

Abstract Lonicera fulvotomentosa Hsu et S. C. Cheng (L. fulvotomentosa), a vine shrub found in Southwestern China, is used for treating epidemic fever and infectious diseases, such as SARS and Avian Influenza. Here, we investigated the chemical composition and nutritional content of dried flowers of L. fulvotomentosa grown in yellow loam and Karst landform soil in Guizhou, China. The moisture content in all samples varied from 3.25 to 3.63%, lipids from 7.76 to 9.93%, fiber from 6.93 to 7.34%, ashes from 12.32 to 12.76%, crude protein from 7.85 to 8.53%, and carbohydrates from 56.21 to 59.77%. Using inductively coupled plasma-mass spectroscopy (ICP-MS), the predominant mineral elements in the dried flowers were found to be calcium (297.34-351.26 mg/kg), potassium (132.56-140.37 mg/kg), iron (37.77–41.25 mg/kg), and magnesium (9.47–11.36 mg/kg). Also, HPLC identified flavonoids (kaempferol, rutin, quercetin, luteolin, and apigenin) and phenolic acids (caffeic acid, gallic acid, and chlorogenic acid). Thus, the chemical composition of L. fulvotomentosa was similar to that of Lonicera japonica Thunb. (L. japonica). Thus, it could be used as an alternative to L. japonica. Our results showed that the dried flower of L. fulvotomentosa had an extremely high content of chlorogenic acids and caffeic acid, which could be developed as a candidate molecule as HIV inhibitors.

Currently, the literature data regarding the concentration of microelements in walnut oil are low, most of them being related to their presence in the walnut core. The purpose of this study was to determine the distribution of essential and toxic mineral elements from walnut oil marketed in Timisoara (Romania) and to evaluate the mineral contribution of this important food in the prevention of cardiovascular diseases. The paper presents the results obtained in determining the content of some essential and toxic microelements of the native walnut oil, used as dietary food. The results obtained from the analysis of the essential and toxic mineral elements, by Inductively Coupled Plasma - Mass Spectrometer (ICP-MS) method, reveal that the walnut oil samples analyzed contain noticeable amounts of: Fe (2,576 - 3,621 mg/kg), Mn (1,876 - 1,783 mg/kg), Zn (1,120 - 1,782 mg/kg), low Cu (0.185 - 0.226 mg/kg), Cr (0.088 - 0.154 mg/kg) and Ni (0.052 - 0.081 mg/kg) and very low Co (0.001 - 0.003 mg / kg). Pb and Cd, elements with pronounced toxic potential, were identified in very low concentrations: 0.020 - 0.031 mg/kg Pb, respectively 0.001 - 0.002 mg /kg Cd. The results obtained when evaluating the mineral intake show that, under the conditions of this experiment, a daily consumption of 30 g of walnut oil cannot be considered as the only additional source of microelements.
