Aloe (Aloe vera L.) is one of the most valuable plants in the pharmaceutical, cosmetic, food and health industries. Due to the growing need for this plant, extensive research has been done on in vitro culture. In vitro propagation of this plant is a convenient and efficient way for the massive proliferation and the use of secondary metabolites. In this study, the best method of sterilization for the explants derived from Aloe vera seedlings and the effects of growth regulators BAP, NAA, and activated charcoal were investigated. The experiment was based on a completely randomized (CRD) design with 3 replications and 5 treatments. BAP at concentrations of 5 and 4 mg per liter, NAA at 0.2 mg per liter, and activated charcoal at 2 grams per liter were used in the MS-medium to induce the lateral buds of seedlings. Fungicide carbendazim 1% (20 min.), alcohol 70% (30 seconds), sodium hypochlorite 2.5% (20 min.), mercuric chloride 0.1% (10 minutes) was identified as the best protocol. In addition, MS-medium with 5 mg/L BAP and 2 grams per liter of activated charcoal was known to be the best environment to induce the lateral buds. The buds obtained in the MS-medium containing 2.0 ppm NAA were rooted and 85% of cuttings survived in the greenhouse.

An experiment was conducted to determine the effect of supplementation of butyric acid and Aloe vera L. on performance, intestinal morphology, blood factors and egg quality in laying Japanese quail. Total of 120 layer quails were randomly assigned to six experimental treatments and five replicates, each with four birds in a completely randomized design for seven weeks. Experimental groups were: 1- control basal diet (Without organic acid and Aloe vera supplements) 2- basal diet+Aloe vera (1%) 3- basal diet +sodium butyrate (500ppm) 4-basal diet+butyric acid glycerides-Baby C4 (500ppm) 5- basal diet +Aloe vera (1%)+sodium butyrate (500) 6- basal diet+Aloe vera (1%)+butyric acid glycerides (500ppm). In this experiment, egg production ratio, feed intake, feed conversion and egg weight were not affected by the treatments. All treatments lowered the cholesterol contents of serum and yolk compared to control group (p<0.01). Treatments significantly influenced jejunum villi (p<0.001). The use of Aloe vera alone and combination of Aloe vera andsodium butyrate or butyric acid glycerides produced eggs with reduced cholesterol content. Simultaneous use of Aleo vera and butyric acid glycerides significantly increased the villi height and surface area and the highest villi width and the deepest villi crypts were observed in this group. In conclusion, supplementation of layer quails’ diets with Aloe vera significantly reduced serum and yolk cholesterol contents, which may confer health benefits to consumers.

Aloe vera L. is considered as one of the most important medicinal species, having high resistance to water scarcity and soil salinity. To investigate the effects of planting date and location on yield and a few characteristics of Aloe vera, a split plot experiment in a randomized complete blocks design was conducted with three replications in 2009. The main treatment included location at two levels (Tekab, 329 m a.s.l and Chahar Farsakh, 930 m a.s.l) and two planting dates including (October 2009 and February 2009) were considered as sub treatments. Data were analyzed in terms of yield per plant, height, leaf length, leaf width, and gel yield. According to the results, the highest yield, plant survival, gel yield and leaf number were obtained from the second planting date (25 Feb.). Also, a significant and positive correlation was found among the studied traits, as leaf number, leaf diameter, and plant height had the highest correlation with flower yield. According to the obtained results, the best planting location and planting date were Tekab (Shahdad) and 25 February, respectively.

Aloe vera L. is one of the most important medicinal plants in the world mostly cultivated due to its economic and medicinal value. In order to study the effects of different levels of nitrogen fertilizer and benzyl adenine hormone (BA) on growth and ramet production of Aloe vera L. a factorial experiment was carried out based on a complete randomized blocks design with four replications in an experimental greenhouse of Faculty of Agriculture, Tarbiat Modares University. Treatments included four levels of nitrogen fertilizer (N1: control, N2: 500, N3: 1000, and N4: 1500 mg per pot) and four levels of benzyl adenine (BA) (BA1: Control, BA2: 500, BA3: 1000, BA4: 1500 mg/L). At the end of the experiment period, plant height, stem diameter, number of ramets, number of leaf ramet, ramet weight, ramet height and total biomass were measured. The results showed that application of 1000 mg nitrogen and 1000 mg/L benzyl adenine had the most effect on the growth factors. Also, application of 1500 mg nitrogen and 1500 mg/L benzyl adenine had the highest effect on ramet characteristics. However, ramet number increased with increment of BA concentration and the highest ramet number was obtained on 1500 mg BA spray treatment without nitrogen application. According to the results, simultaneous application of 1000 and 1500 mg nitrogen and 1000 and 1500 mg\L benzyl adenine had the most influence on the measured factors.

Aloe vera gel and extract has been used in cosmetics and medicine since ancient times. Aloe vera gel has numerous biological and physiological properties including treatment of burns and skin wounds, anti wrinkle effect, stopping the growth of some bacteria and parasites, resistance against chemical synthesis due to the presence of Antrakinon compounds and stopping AIDS virus activity. In order to study the effects of planting density and nitrogen fertilizer on the active ingredients (Aloenin, barbaloin, and Maleic acid) in the medicinal plant Aloe vera L., an experiment was done in Mazandaran, Noshahr in 2009. The experiment was performed as factorial on the basis of randomized complete blocks design in three replications. Nitrogen treatment (urea fertilizer, 46% net nitrogen) was in three levels of 50, 100 and 150 kg/ha and density treatment was in three levels of 2, 4 and 6 plant/m². After extracting the gel from Aloe barbadensis leaf, the amounts of effective material (Aloenin, Barbaloin and Maleic acid) were evaluated by High Performance (Pressure) Liquid Chromatography (HPLC). The highest amount of the active substances and maleic acid obtained from the treatment of 150kg/ha and density of 4 plants /m2 was as follows respectively: 1133/3µg/g aloenin, 429/3 µg/g barbaloin and 312 g/100g maleic acid.

The increase of atmospheric pollutants and depletion of ozone, are subsequently the main causes for the increase of ultraviolet radiation on the earth. In the present research the effect of ultraviolet C (100-280 nm) on the content of some of the biochemical compounds and growth parameters of Aloe vera L. were examined. According to the results, exposure to ultraviolet C decreased both longitudinal and expansion growth, as well as the size of mesophyll layers of aloe leaves, but increased the thickness of cuticle layer. The histochemical methods also showed that phenolic compounds in the cell walls of those plants which were exposed to ultraviolet irradiation were deposited more esterified to the wall polysaccharides rather than being polymerized compared to those of the non-exposed plants. The content of the ultraviolet-absorbing compounds (i.e., anthocyanins and flavonoids) of UV-exposed plants were also changed. Increase of flavonoids and anthocyanins in these plants, may be related to defensive strategy of these compounds against irradiation.

The genus Aloe has been placed in a family called Liliaceae. Aloe vera L. is a tropical or subtropical plant. The gel has been used for years in treatment of burns, wounds, skin irritation, fungual infection and eczema. The use and demand of aloe vera gel has expanded as a result of several stabilization prosses. The leaves of A.vera L. are collected from field of medicinal plants research of National Botanical Garden of Iran (NBGI). The fresh mucilaginous gel contained in the parenchymatous tissue in the center of the leaves, separated from them. The process including the steps of admixing with a heated, A. vera L. gel in the rang of 30°C to 70°C, then added the antioxident effective to prevent oxidation of said gel, adjustment of the gel to a pH in range of from 3 to 3.5, and cooling the gel, in rang of 15 to 20 minets. In 1935 (Tyler), the juce was recommended in treating third-degree X-ray burns.
