First it is very likely that these of their action. They have many roles by acting as antifungal, phytochemicals will find their way into the arsenal of antiviral and antiprotozoal action. They also have essential antimicrobial drugs prescribed by the physicians; several are functions i.e. inhibiting bacterial cell wall synthesis, nucleic already being tested in humans. Scientists realize that the acid synthesis and many more. Medicinal plants are effective lifetime of any antibiotic is limited, so new sources significantly useful and economical. Antimicrobial agents are especially plant sources are also being investigated Second the essentially important in reducing the global burden of public is becoming increasingly aware of the problems with the infectious diseases. With the irrational and excessive use of over prescription and misuse of traditional antibiotics. In antibiotics in underdeveloped and developing countries, there addition many people are interested in having more autonomy may be chances to develop and spread resistant pathogens in over their medical care. A multitude of plants compounds the community. Therefore, the need for novel alternative (often of unreliable purity) is quickly available over the counter antimicrobial strategies has renewed interest in natural from herbal suppliers and national food stores and the Self products like turmeric, honey, ginger and others exhibiting medication with these substances is a common practice to antibacterial properties.

Methods: Wistar rats were subjected to LPS intravenous injection with or without allicin treatment to induce acute lung injury (ALI) model. Also, A549 cells were stimulated with LPS in the presence and absence of allicin. HE staining was used to detect pathological changes in lung tissues. Enzyme-linked immunosorbent assay (ELISA) was performed to measure cytokine content. Cell viability was measured by CCK-8 and EdU incorporation assay. Genes expression was determined by real time polymerase chain reaction (PCR) and Western blot. Flow cytometry was applied to measure cell apoptosis. Results: In vivo data showed that pulmonary edema, inflammatory cytokines expression and pathological changes were significantly attenuated in LPS-induced ALI after treatment with allicin (p < 0.05) while in vitro results indicate that allicin administration significantly improved the A549 cell viability in a dose-dependent manner as measured by CCK-8 and EdU incorporation assay.

  • Chapter 4 Antimicrobial Properties of Organosulfur Compounds
    Chapter 4 Antimicrobial Properties of Organosulfur Compounds Osman Sagdic and Fatih Tornuk Abstract Organosulfur compounds are defi ned as organic molecules containing one or more carbon-sulfur bonds. These compounds are present particularly in Allium and Brassica vegetables and are converted to a variety of other sulfur con- taining compounds via hydrolysis by several herbal enzymes when the intact bulbs are damaged or cut. Sulfur containing hydrolysis products constitute very diverse chemical structures and exhibit several bioactive properties as well as antimicrobial. The antimicrobial activity of organosulfur compounds has been reported against a wide spectrum of bacteria, fungi and viruses. Despite the wide antimicrobial spec- trum, their pungent fl avor/odor is the most considerable factor restricting their com- mon use in foods as antimicrobial additives. However, meat products might be considered as the most suitable food materials in this respect since Allium and Brassica vegetables especially garlic and onion have been used as fl avoring and preservative agents in meat origin foods. In this chapter, the chemical diversity and in vitro and in food antimicrobial activity of the organosulfur compounds of Allium and Brassica plants are summarized.

    Supplement Sampler Garlic – “The Stinking Rose”, “Plant Talisman”, “Camphor of the Poor” SAMe – S-adenosyl L- methionine Best Indications Common cold: reducing incidence and duration.1 Hypertension: drop in systolic (SBP) and diastolic blood pressure (DBP) seen in hypertensive patients.2 Topical ringworm, athlete’s foot, and jock itch: topical application of garlic (in gel or paste form) may help treat dermatophytosis.3 Atherosclerosis: although current evidence suggests that it does not correct hyperlipidemia in humans, garlic has been shown to reduce progression of atherosclerosis via uncertain mechanisms in animal models.4-6 Background Garlic’s scientific name is Allium Sativum. Garlic has been referred to for various treatments in ancient medical texts from Egypt, Rome, China, India, and ancient Sumerians.7,8 Ancient Greek Olympic athletes ate garlic for an athletic boost.7,8 Mechanism of Action Hypertension: current research shows that garlic activates constitutive nitric oxide synthase, thus causing vasodilation and reduction of blood pressure.2 Dermatophytosis and common cold: an organosulfur component found in garlic, ajoene, has been found to have many antimicrobial and antifungal properties, including quorum sensing inhibition and antioxidant action.8,9 Best Studies One study assessed 146 participants over a 3-month period, with half of the participants taking a placebo tablet, and half taking garlic (one capsule containing 180 mg allicin powder per day), noting cold-like symptoms during this period.1 There were 24 occurrences of the common cold in the garlic group, versus 65 in the placebo group (P-value < 0.001), resulting in fewer days of illness in the garlic group compared with the placebo group (111 versus 366).

  • Evaluation of Allicin Stability in Processed Garlic of Different Cultivars
    Food Science and Technology ISSN 0101-2061 DDOI http://dx.doi.org/10.1590/1678-457X.6397 Evaluation of allicin stability in processed garlic of different cultivars Patricia PRATI1*, Celina Maria HENRIQUE1, Aparecida Sônia de SOUZA2, Vera Sônia Nunes da SILVA2, Maria Teresa Bertoldo PACHECO2 Abstract This research aimed at evaluating the suitability of five different garlic cultivars for the processing of unsalted garlic paste, chopped fried garlic, and fried sliced garlic. The concentration of allicin in the products was evaluated immediately after processing and at 45-day intervals during 180 days of storage. Allicin concentrations in raw garlic of the varieties under study differed (20.73 a 24.31mg of allicin g–1 garlic). Stability exhibited a similar between the varieties according to the type of processing utilized. Processing into paste was more favorable to the preservation of allicin than the other processes. The amount of allicin lost during the process to obtain paste for the different varieties was less than 9.5%, and it reached a maximum loss of 22% for the commercial varieties during storage (180 days). All fried garlic samples showed a decrease by 99% in the content of allicin right after processing. The processing of garlic in the form of acidified paste preserved its bioactive characteristics during storage. Keywords: bioactive compounds; allicin stability; Allium sativum L.; garlic fried; garlic paste. 1 Introduction Garlic (Allium sativum L.) occupies a prominent position Although considered non-nutritive, the compounds formed among human foods, not only as a condiment, but also due from the decomposition of alliin play an important role in the to its therapeutic properties, attributed to the presence of diet as antioxidants, protecting against certain degenerative bioactive compounds (Tepe et al., 2005).
