Antimicrobial activity

Antimicrobial activity of natural plant extracts is an important topic in biology and medicine. Plants are known for their many secondary metabolites, such as flavonoids, steroids, glycosides, terpenoids, and saponins. These compounds may be responsible for the antimicrobial activities of plants. They may also have therapeutic potential. Therefore, understanding the mechanisms of action of these compounds is an essential first step towards optimum utilization of these plants.

A variety of studies have been conducted to evaluate the phytochemical compositions and the antimicrobial activities of different plants and its extracts. Various plant species are used in traditional medical systems in different parts of the world. Some plants have been used for centuries as a source of medicinal products. However, few studies have been carried out to evaluate the antimicrobial activities of these plants in Ethiopia.

In the current study, five herbal extracts with strong antimicrobial activity were investigated. The extracts included ziziphusspina Christi, Maesa lanceolata, mulberry, guava, and olive. All the extracts were tested for their ability to control the growth of bacteria. Although cytotoxicity was measured, it was not always associated with the activity of the extracts.

The disc diffusion method was utilized to test the antimicrobial activity of the various plant extracts. The test bacteria were inoculated on sterile paper discs. After 5 minutes, viable bacterial cells were collected. MIC values were calculated against Gram-negative and Gram-positive bacteria.

MICs ranged from 0.02 to 0.52 mg/mL for the medicinal plant extracts. The results indicated that these extracts were effective against all the pathogens studied. Nevertheless, the difference between the concentration and the plant species was not significant.

The results showed that all the plant extracts contained a bioactive compound with a Rf value of about 0.12. This may be attributed to the natural chemical composition of the plant. However, further investigations are necessary to confirm the biological ingredients and their effectiveness against the tested pathogens.

Cytotoxicity was measured by the total aqueous antimicrobial activity (TAA) and selectivity index (SI). Extracts were most active against Staphylococcus aureus and Bacillus cereus. Several other bacterial species were relatively resistant. An extract with high TAA was found to be more effective against Candida albicans.

Among the extracts, the aqueous extract of roselle showed a high inhibitory effect against Candida albicans, but there was no significant difference between the plant species and the concentration. Another extract, the ethanolic one, showed antifungal effects against CA. It was concluded that all the five plants exhibited strong antimicrobial activity. Moreover, they could be used as food preservatives, as well as for controlling microbial populations.

Currently, there are hundreds of antibiotics manufactured to combat various microbial infections. These products are often toxic, and they have negative side effects for consumers. Alternatively, herbal drugs are used to treat microbial infection. Besides their antimicrobial properties, these plants have also been shown to have therapeutic and food additive properties.

Preservative properties

Preservative properties of natural plant extracts play an important role in food preservation and natural extract. They act as antimicrobial and antioxidant agents, preventing spoilage and oxidation of foods. However, the molecular mechanisms of these bioactive compounds are not fully understood. Therefore, it is necessary to evaluate the efficacy and safety of plant extracts as preservatives.

Natural preservatives have attracted a lot of attention in the scientific community. Their use has also gained a lot of interest from consumers. However, the food industry is still heavily dependent on synthetic chemical preservatives, which may be dangerous for human health. Fortunately, some natural plant-based alternatives have been introduced. These are based on natural antioxidants such as polyphenols.

Although plant-derived antimicrobials have the potential to be used as a food preservative, their potential is still limited. This is because they are still in their infancy. In fact, most studies on plant polyphenols have been conducted in vitro. However, a growing trend is towards the rapid expansion of their use in health products.

Polyphenols have been extracted from fruits, vegetables, and herbs. Studies have shown that the antioxidant activity of these compounds can be as high as one million times higher than the total protein oxidation. Because of their bioactivity, plant-derived preservatives can replace chemical preservatives. Moreover, they offer a cost-effective alternative. Compared to synthetic food preservatives, they have no documented negative effects.

Physicochemical stability of the plant extracts was observed up to 45 days in different storage conditions. In addition, they had comparable physicochemical properties to common synthetic preservatives. It is therefore possible to use plant-based extracts as substitutes for BHT, TBHQ, sodium benzoate, and potassium sorbate.

Antimicrobial activities of plant-derived preservatives are influenced by the OH-group positions of the compounds. For instance, carvacrol OH-groups are located at the ortho position while thymol OH-groups are located at the meta position.

Plant extracts have an important function in the meat industry. They can control the growth of pathogenic microorganisms and preserve the quality of the meat. Aside from their antioxidant and antimicrobial properties, plant extracts can also be used as a quality monitoring tool. When combined with antibiotics, they can lower the risk of antibiotic resistance. Moreover, they can also reduce the formation of N-nitrosamines and nitrites.

Some plant extracts have been approved by the US Food and Drug Administration and the European Union. Rosemary is one such preservative. The maximum recommended level of rosemary is 150 mg/kg. Similarly, betel leaves, ginger, licorice, cinnamon bark, and galangal have been found to have antimicrobial properties.

Despite the fact that synthetic chemical preservatives have a wide application in the food industry, consumers are now seeking healthier alternatives with botanical powder. Consumers are skeptical about the safety of these preservatives. Luckily, natural preservatives have gained popularity and are being used more frequently.

During the past years, the search for natural preservation techniques has increased. While these techniques can provide better results, they often require a large amount of raw material. Furthermore, the strong aroma of essential oils can alter the organoleptic properties of the food. Choosing the right essential oil for the type of food is the best way to minimize this issue.

Can be used as a skincare ingredient

Choosing the right skincare products is a crucial step in improving your overall skin health. You can get some amazing results from a variety of different ingredients and pairing them together can make a big difference. However, some active ingredient combinations may be best avoided, especially when trying to treat specific skin issues. If you are unsure how to choose the right combination for your skin type, here are a few tips.

Vitamin E is an antioxidant that is often used in skincare. Among other benefits, this compound helps protect your skin from free radical damage. In addition, it also provides anti-bacterial properties. When applied to your skin, vitamin E can improve your complexion by reducing oiliness and brightening your skin. But keep in mind that its antioxidant levels can be reduced by exposure to sunlight.

Evening primrose is an effective moisturizer and can help smooth out rough, dry, or scaly skin. It is also a powerful antioxidant that can inhibit DNA damage in certain cells. It is a popular skincare ingredient, and can be found in a variety of over-the-counter products.
