Several natural polymers have application in terms of therapeutic treatment of ailments. Chitosan, Aloe Vera and Calendula officinalis have proven wound healing properties individually. It was theorized that a combination of the biopolymer and the plant extract will show an improvement in wound healing properties. Thus, composite films of Aloe Vera extract in Chitosan and C. officinalis petal extract in
Chitosan were prepared and evaluated to ascertain the applicability for wound healing. The chemical composition and mechanical, morphological, and surface characteristics including the antibacterial activity were also evaluated. The optimum conditions for obtaining a maximum percentage of composition were standardized. Their mechanical properties, water absorption characteristics and compatibility were analyzed by tensile tester, FTIR and SEM analyses. The composite films containing aloe vera had higher water absorption capacity and antimicrobial activity as compared to those containing C. officinalis petal extract. The films containing C. officinalis petal extract showed higher tensile strength as compared to those containing Aloe Vera. With the above results, it was concluded that a composite of 25% Aloe Vera in Chitosan can be used as a wound dressing amongst all the combinations.

The aim of this work was to develop an organic and sustainable cultivation protocol, based on the use of microbial biofertilizers (Plant Growth Promoting Rhizobacteria, Trichoderma spp., arbuscular mycorrhizae and biostimulant algae) able to improve the growth and quality of Aloe barbadensis Miller plants. The experimental trial at CREA-OF in Pescia showed a significant improvement in the agronomic parameters analysed on Aloe barbadensis Miller plants treated with microbial and algae-based biofertilizers. In particular, there was a significant improvement in the number of leaves per plant, new shoots, vegetative fresh weight, root weight and gel weight. On the leaves in the treated theses, there was a significant increase in leaf length and width and an improvement in gel quality (optical density). The trial also showed a significant improvement in soluble solids, sugars and fibre content in the theses inoculated with microbial products and a significant increase in fructose, glucose, proline and aloin. These improvements in plant growth following the use of microbial biofertilizers and algae have also been found in previous trials in other vegetables and ornamental crops, but few trials have been carried out with Aloe. The application of symbiotic microorganisms in agricultural operations can therefore ensure higher production standards, with a possible improvement in the agronomic quality of the plants, while also reducing the use of water and fertilizers. This experiment may be of particular interest to farms that want to focus on the production of ornamental and fruit cacti and succulents under organic farming methods.
The effect of high pressure processing (HPP) (600 MPa/15 min/56 °C) and thermal processing (TP) (95 °C/5 min) on the quality characteristics of aloe vera-litchi mixed beverage samples (ALMB) stored at 4, 15 and 25 °C were studied. The... more
The effect of high pressure processing (HPP)
(600 MPa/15 min/56 °C) and thermal processing (TP)
(95 °C/5 min) on the quality characteristics of aloe
vera-litchi mixed beverage samples (ALMB) stored at
4, 15 and 25 °C were studied. The total color difference and
browning index of ALMB samples increased with the storage
period for both HPP and TP treated samples under all storage
conditions. HPP of ALMB resulted in inactivation of
pectinmethylesterase (PME), polyphenoloxidase (PPO) and
peroxidase (POD) to 34, 65 and 62 %, respectively after immediate processing, whereas, TP treatment lead to 83, 79 and
78 %, respectively. The residual activity of all the studied
enzymes decreased with storage period. The ascorbic acid loss
of up to 22 % was observed after HPP treatment and up to
31 % for thermally treated samples. Minimal changes were
noted for phenolics content after HPP as well as thermal processing. The natural microbiota present in samples was below
the detection limit (1 log CFU/mL) throughout the storage
period. The shelf life of HPP and TP treated samples stored
at 4 °C was estimated to be 100 and 80 days, respectively,
based on the sensory quality, ascorbic acid degradation and
instrumental color difference.

Research goal: The aim of this work was to develop a sustainable and innovative organic cultivation protocol, usable by local Italian companies, based on the use of microbial biostimulants (beneficial bacteria and fungi, arbuscular mycorrhizae and algae) able to improve the growth and quality production of the medicinal gel of Aloe vera. Materials and Methods: The experiments, started in December 2020, were conducted in the greenhouses of CREA-OF in Pescia (Pt), Tuscany, Italy (43°54′N 10°41′E) on Aloe vera (4 year old plants). The experimental groups were: i) group control, irrigated with water and substrate previously fertilized; ii) group with Effective microorganisms irrigated with water and substrate previously fertilized; iii) group with Trichoderma spp. irrigated with water and substrate previously fertilized; iv) group with arbuscular mycorrhizae irrigated with water and substrate previously fertilized; v) group with Ascophyllum nodosum irrigated with water and substrate previously fertilized. Results and Discussion: The experiment showed a significant improvement in agronomic parameters and physical, chemical and microbiological characteristics analysed on plants treated with microbial and algae-based biofertilizers. In particular, there was a significant improvement in the number of leaves per plant, new shoots, fresh vegetative weight, root and gel weight and the inflorescences number. On the leaves of the treated theses, there was a significant increase in leaf length and width and an improvement in gel pureness (optical density). There was also an increase in the number of microorganisms in the treated substrates and a lowering of the pH of the growing medium. The test also showed a lowering of the pH of the gel and a significant increase in soluble solids, sugars and fiber content in the theses inoculated with Effective microorganisms and a significant increase in fructose, glucose, proline and aloin. Conclusions: The trial confirms the significant results already obtained in other trials on vegetable, ornamental and Aloe plants by applying biofertilizing microorganisms and algae. The aim of this work was to develop an organic cultivation protocol based on microbial and algae treatments that can be used to improve the quality of Aloe vera plants. This protocol can be applied in general by those companies that are dedicated to the production of ornamental and fruit cacti and succulents and want to reduce or even eliminate the use of plant protection products

El cultivo in vitro consiste en cultivar un explante con potencialidad de diferenciación bajo condiciones asépticas en presencia de una dieta balanceada de nutrientes y hormonas. Estas a la vez son condiciones ideales para el crecimiento y proliferación de microorganismos contaminantes, esterilizar los medios de cultivo, desinfectar los instrumentos, la cámara de transferencia de flujo laminar y limpiar los cuartos de trabajo.

John Goodyew translated first reference from term ‘Dioscorides Medical treatise De Materia Medica’ into English
terminology as use of Aloe vera in A.D. 1655; moreover, in early 1800s it used as laxative whereas in the mid 1930s
successful treatment was introduced for chronic and severe radiation dermatitis. Since, several cultures of the history
have been showed impression of foot print for use of Aloe vera, major includes Greece, Egypt, India, Mexico, Japan
and China. Egyptian queens Nefertiti and Cleopatra regularly involved it in their beauty regimes whereas Alexander
the Great, and Christopher Columbus used it to treat soldiers’ wounds. Aloe vera is well known plant not only in tribal
community but modern lookout also make it therapeutic important. Since it is used in Ayurvedic, Homeopathic and
Allopathic medicine because various research support that it contains vitamins, minerals, enzymes, amino acids,
natural sugar and other bioactive compounds. Although therapeutic use of Aloe vera covered wide range of activity
major includes emollient, purgative, antimicrobial, anti inflammatory, antioxidant, aphrodisiac, anti-helmenthic,
antifungal, antiseptic and cosmetic, its benefits so myriad and astounding that no part in human body remains
uninfluenced by its healing touch; all these make it plant of wonder. The modern therapeutic approach for beauty enhancer also list Aloe vera as most favorable plant in cosmetic industries. In this review we are trying to approach and underlying every possible corner associated with medicinal use of Aloe vera.
