Nutraceutical, therapeutic, and pharmaceutical potential of Aloe vera A review Upadhyay International Journal of Green Pharmacy (IJGP)
The present review explains therapeutic and pharmaceutical potential of Aloe vera a well-known plant grows in semi-arid climate of tropical and subtropical regions. This article emphasizes important uses of A. vera constituents as dietary nutraceutical, medicinal, and therapeutic potential. Plant is cultivated for agricultural and medicinal and decoration purposes for indoors as a potted plant. Plant is a good depository of chemical constituents which display a very wide array of biological activities such as anticancer, antiparasitic, antidiabetic, anti-inflammatory, anti-arthritic, antiparasitic, antitumor, antioxidant, chemopreventive, hepatoprotective, and gastroprotective. Plant is used to prepare skin protective/care gels mainly for soothing, moisturizing, and wound healing. Thick watery plant sap works are added as key ingredient in many beauty products. Plant leaves are used to generate aroma, beverages, skin lotion, cosmetics, or ointments for minor burns. Plant contains vitamins, enzymes, minerals, sugars, lignin, saponins, salicylic acids, and amino acids as main ingredients. Plant is a good source of Vitamins A, C, and E, which are antioxidants. It also contains Vitamin B12, folic acid, and choline watery juicy of A. vera leaf which contains important minerals such as calcium, chromium, copper, selenium, magnesium, manganese, and potassium. Plant ingredients were found active against gingivitis, psoriasis, and used for herbal therapy in inflammatory bowel disease. A. vera contains important fatty acids mainly steroids such as cholesterol, campesterol, β-sitosterol, and lupeol. Aloin and emodin act as analgesics, antibacterials, and antivirals while lupeol shows antiseptic and analgesic properties.

Aloe vera and garlic ameliorate deleterious consequences of thermoxidi (...)
A plethora of publications have reported several cytotoxic effects associated with chronic consumption of thermoxidized palm oil. This research aims to investigate the effects of garlic and Aloe vera on liver function and hepatic cytoarchitecture in rats fed thermoxidized palm oil diet.,Thirty-five male albino Wistar rats weighing 150-180 g were used for this study. They were randomly assigned into five groups (n = 7): control, thermoxidized palm oil diet fed (TPO), TPO plus garlic juice (TPO + G), TPO plus Aloe gel (TPO + A) and TPO plus garlic/Aloe gel (TPO + G + A). The TPO diet was prepared by mixing 15 g of cooled thermoxidized palm oil with 85 g of rat feed. The juice and gel were orally administered at doses of 2.00 ml/kg and 19.12 ml/kg, respectively. After 3 months of feeding and administration, the animals were sacrificed using standard methods and blood collected via cardiac puncture for analysis.,Serum alanine aminotransferase (ALT), aspartate aminotransferase (AST) and alkaline phosphatase were significantly increased (p < 0.001) in the TPO group compared to the control. This increase was reduced (p < 0.001) in all the treated groups compared to TPO, with the greatest decrease (p < 0.001) seen in TPO + A. Total bilirubin was increased (p < 0.001) in the TPO group compared to the control, whereas there was a significant decrease (p < 0.001) in all the treated groups. Serum proteins and plasma fibrinogen were lowered (p < 0.001) in the TPO group compared to the control but increased progressively in all the treated groups. TPO induced prominent histopathological derangements of the liver tissues. However, there were marked improvements following treatment with garlic and Aloe vera.,The results obtained in this study have revealed that chronic consumption of thermoxidized palm oil is hazardous to health by inducing hepatotoxicity, as seen in increased ALT, AST and total and unconjugated bilirubin and decreased total protein. However, these debilitating effects were seen to be greatly ameliorated following garlic juice and Aloe vera gel administration. If these results are to be extrapolated to humans, then the chronic consumption of thermoxidized palm oil diet should be seriously discouraged.
Pharmaceutical applications of Aloe vera Heng INDONESIAN JOURNAL OF PHARMACY
Aloe vera has been used as folk medicine for a host of therapeutic indications of which the inner gel is the component extensively used and studied. Proponents of the use of this plant suggest that it is easily available, economical, and have fewer side effects compared to commercial drug compounds. However, the active constituents and their exact mechanisms have yet to be fully elucidated. This review focuses on the identification of the active constituents and their functional mechanism in the areas of anti-diabetic, anti-inflammatory, wound healing, and antibacterial. Preliminary evidence was found to support the antidiabetic effect which extended to the early stages of the disease with no adverse effects at the dosages used. Although topical application for its anti-inflammatory effect may be delayed and minute, oral administration has shown a significant response. However, too high a dose has been linked with an initial inflammatory reaction. Favorable response to the gel has also been demonstrated to support the use of A. vera in wound-healing and as an antibacterial agent, although limited to simple, uncomplicated wounds. Different active constituents such as acemannan and aloin have been suggested for the effects of the plant and this may be interpreted as synergism among different compounds rather than the action of a single compound. Until robust evidence is available, the plant should only be used as an adjunct to other well-established evidence-based treatment modalities.

Symbiotic effect of Aloe vera juice on the growth of Lactobacilllus fe (...)
AIM: Long-term dietary intake of non-caloric fiber, such as Aloe vera gel influences the structural and activity of micro-organisms in the human gut. The present investigation was executed with an innovative concept: symbiotic effect of probiotics that are used commercially as lactic acid bacteria i.e. Lactobacillus fermentum and Aloe vera juice as prebiotics for a prospective prophylaxis. MATERIALS AND METHODS: Fermentation of L. fermentum with Aloe vera juice certified by International Aloe Science Council was carried out and the quantification of short chain fatty acids (SCFAs) from the fermentation broth in large scale was determined by gas-chromatography-mass-spectrometry selective detection in the selective ion monitoring mode. RESULTS: The growth of L. fermentum and L. helveticus with Aloe vera juice (AVJ) individually on MRS broth was continued to keep at pH 3.5 and 3.6, while pH of the negative controls changed to 4.3 and 4.0, respectively, during 24 hr incubation. The growth rate and the viability of L. helveticus incubated with different concentrations (5-25%) of Aloe vera juice were strongly reduced. However, the growth rate of L. fermentum was enhanced in a concentration dependent manner with emphasis on the use of 15% AVJ that resulted in two times more growth than that of the negative control. Continuation of L. fermentum growth at pH 3.6 in combination with AVJ during incubation for 24 hr suggests the durability of prebiotic potential by AVJ in in vitro fermentation. Acetic, propionic and lactic acid as SCFAs in the ether extract were identified from the fermentation culture medium. CONCLUSION: The prebiotic activity of AVJ may be assessed by the participation of SCFAs during 24 hrs-incubation with L. fermentum. An innovative concept of symbiotics: a combination of AVJ and L. fermentum, is a perspective prophylaxis on future intestinal health claims. Due to tolerance to acid, L. fermentum may pass through the gastric barrier and colonize the intestine after oral administration.

Shape- and Size-Controlled Synthesis of Silver Nanoparticles Using Alo (...)
Abstract Biogenic synthesis of silver nanoparticles (AgNP) was performed at room temperature using Aloe vera plant extract in the presence of ammoniacal silver nitrate as a metal salt precursor. The formation of AgNP was monitored by UV-visible spectroscopy at different time intervals. The shape and size of the synthesized particle were visualized by scanning electron microscopy (SEM) and transmission electron microscopy (TEM) observations. These results were confirmed by X-ray powder diffraction (XRD) and Fourier transform infrared spectroscopy (FTIR) analyses and further supported by surface-enhanced Raman spectroscopy/Raman scattering (SERS) study. UV-visible spectrum has shown a sharp peak at 420 nm and further evidenced by FTIR peak profile (at 1587.6, 1386.4, and 1076 cm−1 with corresponding compounds). The main band position with SERS was noticed at 1594 cm−1 (C–C stretching vibration). When samples were heated under microwave radiation, AgNP with octahedron shapes with 5–50 nm were found and this method can be one of the easier ways to synthesis anisotropic AgNP, in which the plant extract plays a vital role to regulate the size and shape of the nanoparticles. Enhanced antibacterial effects (two- to fourfold) were observed in the case of Aloe vera plant protected AgNP than the routinely synthesized antibiotic drugs.
