Monofloral Iranian honeys from eight floral sources were analyzed to determine their anti-HIV-1 activities as well as their effects on lymphocyte proliferation. The Peripheral Blood Mononuclear Cells PBMCs used in this study were prepared from five healthy volunteers who were seronegative for HIV, HCV, HBV and TB. The anti-HIV-1 activity of eight different honeys was performed by quantitative polymerase chain reaction PCR assay and high pure viral nucleic acid kit. The results demonstrated that monofloral honeys from Petro selinum sativum, Nigella sativa, Citrus sinensis, Zataria multiflora, Citrus aurantium and Zizyphus mauritiana flowers had potent anti-HIV-1 activity with half maximal effective concentration EC50 values of 37.5, 88, 70, 88, 105 and 5 µg-ml respectively. However, monofloral Iranian honeys from Astragalus gummifer and Chamaemelum nobile flowers had weak anti-HIV-1 activity. The frequency and intensity of CD4 expression on PBMCs increased in the presence of all honey types. CD19 marker were also increased after the treatment with monofloral honeys from Z.multiflora and N. sativa. The anti-HIV-1 agent in monofloral honeys from P.sativum, N. sativa, Z. multiflora and Z. mauritiana flowers was detected by spectroscopic analysis as methylglyoxal. Time of drug addition studies demonstrated that the inhibitory effect of methylglyoxal is higher on the late stage of HIV-1 infection. The result demonstrated that methylglyoxal isolated from monofloral honey types is a good candidate for preclinical evaluation of anti-HIV-1 therapies.
