Finding non-invasive skin depigmenting agentsrepresent an important goal of cosmetic research and industry. It is now admited that Tyrosinase inhibitor substances could be the most efficient molecules in this field because Tyrosinase is the key enzyme in the melanogenesis process. In the pathology of macular skin hyperpigmentations it can mention aesthetic problems such as: melasma gravidarum, pigmentation of aged skin, photosensibilisation, hepatic disfunctions and post-inflammatory residual pigmentation. The aim of the study was to find out if the Lavandula essential oil has depigmenting properties on human skin, having as theoretical premise its tyrosinase-blocking effect, previously reported in literature for some plant species. By using gas chromatograph coupled with mass spectrometer (GC/MS), a pharmaceutical cream preparation, a protocol of exploration on volunteers (including criteria) and a mexameter, we have highlighted the composition of a sample of Lavandula angustifolia essential oil (LEO) and its depigmenting effect on skin melanic macula. The results highlightes that the main compounds identified were linalool (26.783%), terpinen-4-ol (22.143%) and 3-carene(21.668%), Terpinen-4-ol is represented as the possible active compound in tyrosinase inhibition. Our dermocosmetic assay shows that the depigmenting effect of Lavandula angustifolia oil is effective after 2 months of daily topical treatement, when the melanine average value (measured by the mexameter) decreases more than a third from the innitial value. The study remarks that Lavandula angustifolia essential oil (LEO) in daily cutaneous pharmaceutical form application, during two month, reduces the intensity of spot skin melanin, exprimed through mexametric values.Keywords: Lavandula angustifolia L.; tyrosinase inhibitor; melanic skin macula.

“…Mineral content in different stages of fruits of Mespilus germanica was studied by Glew et al, 2002 [7]. Elemental analysis of some medicinal plants from Spain was studied by Queralt et al [8], in 2005, particularly, from the plants of family Lamiaceae by Ražić et al, 2005b [9]. Metallic mineral elements in a large number of medicinal plants collected from Europe and Mediterranean region and were studied by Chizzola in 2011 [10].…”

“…This technique (WDXRF) is widely used to detect the elements in algae, in tea [17], milk-based products [18], in spices [14], of some plants used as condiments (Ӧzcan, 2004) [19], in medicinal plants [8,20], mineral composition of ten commercially available teas [21], and in potato starch by Noda et al, 2006 [22]. Previously, the mineral content in milk based products [23], in yoghurt [24], in legumes and nuts [25] and in some essential oils [26] was also estimated.…”

Ojective: This study is undertaken to identify the total mineral content of both the cytotypes from different plant parts, i.e., fruit, leaf, stem, and roots.Method: Wavelength dispersion X-ray fluorescence technique is a simple method, recognized as a nondestructive technique to determine the elements from the raw plant material without any chemical treatment and helps to ascertain the nutritional role. Result:The analysis of mineral content led to the identification and concentration analysis of twenty-seven elements in diploid cytotype and twentyfive in tetraploid cytotype. The percentage value of potassium (5.52%); iron (0.50%) and selenium (0.0042%) is reported to be higher in diploid cytotype and the amount of calcium (2.15%); magnesium (0.75%) and zinc (0.0075%) are higher in tetraploid cytotype.

Conclusion:The amount of most of the minerals is higher in tetraploid cytotype as compared to the diploid cytotype. This information is very helpful in standardization of herbal products as this plant species is widely used for its medicinal benefits. Tnt of calcium (2.15%); magnesium (0.75%) and zinc (0.0075%) are higher in tetraploid cytotype..

“…Phosphorus (P), potassium (K), sodium (Na), calcium (Ca), magnesium (Mg), sulfur (S) and chloride (Cl) concentrations were determined by wavelength-dispersive X-ray Fluorescence Spectrometer (WDXRF) (Bruker AXS, S4 Pioneer). The XRF has an advantage for simultaneous measurement of the elements present in plant samples with direct analysis (Queralt et al 2005). Pellet of plant powder can hardly be done without addition of a binder; we prepared a powder pellet by mixing 3 g of plant powder with 1 g of boric acid (binder) and homogenized (Saini et al 2002).…”

Irrigation with diluted seawater would be an alternative water resource which can play an important role under scarce resources of freshwater for promoting agricultural production in coastal areas. Salvadora persica Linn. was irrigated with different concentrations of seawater (0, 10, 20, 40, 60, 80 and 100 % seawater), and their effect on plant growth, nutrient contents in soil and plants, shift in soil microbial community structure (phospholipid fatty acid; PLFA) and community-level physiological profiling (CLPP, Biolog ECO MicroPlate) were studied. Plant dry matter was significantly increased with all seawater treatments, and highest increase was at 20 % seawater treatment. Sodium and chloride contents were significantly increased, whereas ratios of K/Na and Ca/Na were significantly decreased in plants with seawater irrigation. Soil electrical conductivity (EC), available K and Na were significantly increased with increasing the concentration of seawater. Total PLFA concentration and PLFA profile of soils were used as indices of total microbial biomass and community composition, respectively. The concentrations of total PLFA, gram-positive, gram-negative and actinomycetes biomarker PLFAs were significantly reduced at 20, 40, 80 and 40 % concentrations of seawater, respectively. The application of different concentrations of seawater induced a clear shift in the soil microbial community structure toward the bacterial abundance. The microbial community structure and community-level physiological profiling in seawater irrigation treatments had significantly differentiated. It can be concluded that irrigation with different concentrations of seawater had significant impact on soil chemical and microbial properties which is attributed due to the salinity stress.
