“…38 Another compound detected, which is worth mentioning, is 1-oxa-4,6-diazacyclooctane-5-thione, which was found to be present in 'rosy garlic' (Allium roseum L.) and was reported in the study to not have been recorded in the literature. 39 As a result of various compounds highlighted in different studies on components of garlic, Amagase 15 speculated that, while garlic is recognised for the abundance of sulphur compounds present, perhaps compounds other than allicin could contribute to the various antimicrobial activities. The present study supports this hypothesis as allicin was not found in the sample tested; however, other sulphur and sulphurderived compounds were found in high amounts.…”

HOW TO CITE:Daniel CK, Lennox CL, Vries FA. In-vitro effects of garlic extracts on pathogenic fungi Botrytis cinerea, Penicillium expansum and Neofabraea alba. In-vitro effects of garlic extracts on pathogenic fungi Botrytis cinerea, Penicillium expansum and Neofabraea albaThe antifungal activity of garlic extracts applied directly and through volatile release was tested against the growth of postharvest pathogens Botrytis cinerea, Penicillium expansum and Neofabraea alba. Mycelial growth of B. cinerea and P. expansum was inhibited by aqueous and ethanol dilutions on garlic extract amended media (direct method) in a dose-response manner. The aqueous dilution was more effective than the ethanol dilution. Both dilutions inhibited mycelial growth of N. alba to a similar extent but no trend in data was noted across the concentration range. Calculated EC 50 values indicated that 13.36% and 8.09% aqueous dilutions could be used to inhibit growth of B. cinerea and P. expansum, respectively; however, values generated for N. alba either bordered on or exceeded the concentration range. The volatile vapour application of garlic was able to inhibit mycelial growth and spore germination of all pathogens at concentrations as low as 20%. Gas chromatography-mass spectrometry analysis showed that 85.95% of compounds present in the garlic sample belonged to a sulphur or sulphur-derived group. Allicin, the active component of garlic, was not found; however, breakdown products of allicin were present in high amounts. Overall, the antifungal activity of garlic extracts for the control of B. cinerea and P. expansum was confirmed. Further investigations into the antifungal effect of garlic extracts on N. alba is required, although garlic volatiles seem to be effective. This report is the first of antifungal activity of garlic extracts against N. alba -the causal agent of bull's eye rot, one of the major diseases of apples.

International audienceAllium roseum L. (Alliaceae) endemic mediterranean specie was represented in the North Africa by 12 different taxa. In the present study, chemical composition, antiproliferative, antioxidant and antimicrobial activities of the essential oil extracted from A. roseum var. grandiflorum Briq. bulbs collected in the North of Tunisia were investigated. Chemical characterization has shown methyl methanethiosulfinate as major sulphurous compounds. A. roseum bulbs essential oil provides interesting antiproliferative activity against two human colonic adenocarcinoma HT29 and CACO2 cell lines in dose-dependent manner with a half-maximal inhibition (IC50) of 4.64 µg/mL and 8.22 µg/mL respectively. The antioxidant activity, as determined by FRAP assay, was 285 µmol equivalent Trolox/g of essential oil. The scavenging effect on DPPH radicals of essential oil was estimated as IC50 values at 156 µg/mL. The inhibition of superoxide anion production in a model of cancer cell lines was significant for both lines HT29 and CACO2 with IC50 of 20.25 µg/mL and 29.12 µg/mL respectively. Allium roseum essential oil exhibited antibacterial and antifungal activities with a high effectiveness against Candida albicans given by an MIC value of 0.019 mg/mL. This biological effect appears to be related mainly to the presence of organosulfur compounds
