Genotoxicity evaluation of the naturally-derived food colorant, gardenia blue, and its precursor, genipin.

Gardenia blue is widely used in Eastern Asia as a natural food colorant. To evaluate the genotoxic potential of gardenia blue, as well as genipin, the natural starting material from which it is produced, a GLP-compliant test battery was conducted according to OECD guidelines. No evidence of mutagenicity of gardenia blue was detected in a 5-strain bacterial reverse mutation assay, with or without metabolic activation; an equivocal response for genipin occurred in S. typhimurium TA97a without metabolic activa...

A novel strategy for evaluation of natural products acting on the myeloperoxidase/hypochlorous acid system by combining high-performance liquid chromatography-photodiode array detection-chemiluminescence and ultrafiltration-mass spectrometry techniques.

Myeloperoxidase and its product hypochlorous acid are endogenous substances that are involved in the pathogenesis of many inflammatory diseases. In the present study, a novel evaluation strategy has been developed to screen for myeloperoxidase inhibitors and hypochlorous acid scavengers in natural products. The evaluation strategy uses two methods: a multi-hyphenated high-performance liquid chromatography-photodiode array detection-chemiluminescence online method, and an ultrafiltration-high-performance liq...

Green synthesis and characterization of biologically active nanosilver from seed extract of Gardenia jasminoides Ellis.

This article reports the utilization of seed extract (GSE) from Gardenia jasminoides Ellis. in the synthesis of silver nanoparticles (Gs-AgNPs) with versatile biological activities. The synthesized Gs-AgNPs were spherical in shape, crystal lattice with an average size of 20 nm as confirmed by UV-vis spectrum, X-ray diffractometer (XRD), Transmission electron microscopy with Energy dispersive X-ray spectroscopy (TEM-EDS) and particle size analyses (PSA). Phenolic compounds, proteins, and terpenoids were li...

Geniposide protects PC-12 cells against oxygen and glucose deprivation-induced injury by up-regulation of long-noncoding RNA H19.

Hypoxic-ischemic encephalopathy (HIE) is a common brain injury disease in neonates, which can lead to neonatal disability and death. Geniposide (GEN) is a main ingredient of Gardenia jasminoides whose anti-tumor, anti-inflammatory and anti-apoptotic effects have been reported in various diseases. However, the effect of GEN on HIE remains uninvestigated. This study aimed to clarify the protective effect of GEN on PC-12 cells against oxygen and glucose deprivation (OGD)-induced injury.

Geniposide reduces Staphylococcus aureus internalization into bovine mammary epithelial cells by inhibiting NF-κB activation.

Staphylococcus aureus (S.aureus), a Gram-positive organism, is a frequent cause of subclinical mastitis. Geniposide, an iridoid glucoside isolated from the fruits of Gardenia jasminoides, has been reported to exhibit antibacterial and anti-inflammatory properties. The ability of S. aureus internalizing into bovine mammary epithelial cells (bMEC) has been responsible for the establishment of the bovine mastitis. In this study, we evaluated the effect of geniposide on S. aureus internalization into bMEC and i...

Natural curing agents as nitrite alternatives and their effects on the physicochemical, microbiological properties and sensory evaluation of sausages during storage.

This study investigated the effects of different curing agents on the physicochemical properties, microbiological properties and sensory evaluation of sausages formulated with and without nitrite over 4 weeks of cold storage. Seven batches were prepared: control, sodium nitrite 0.01%; celery powder 0.8% (T1); fruit extract powder 0.6% (T2); purple sweet potato powder 0.45% (T3); fruit and vegetable extract powders 0.5% (T4); gardenia red 0.04% (T5); paprika and blueberry powder 0.07% (T6). T1 produced sig...

Potential role of genipin in cancer therapy.

Genipin, an aglycone derived from the iridoid glycoside, geniposide, is isolated and characterized from the extract of Gardenia jasminoides Ellis fruit (family Rubiaceae). It has long been used in traditional oriental medicine for the prevention and treatment of several inflammation driven diseases, including cancer. Genipin has been shown to have hepatoprotective activity acting as a potent antioxidant and inhibitor of mitochondrial uncoupling protein 2 (UCP2), and also reported to exert significant antica...

Computational simulations of the mass transfer zone in GS adsorption column packed with Fe type ion exchanger.

In this work, a mesoporous Fe type ion exchanger (DOW-3) was used to adsorb the geniposide (GS) involved in gardenia yellow pigment waste water. To test its viability, the mass transfer zone (MTZ) in dynamic adsorption column that plays an important role in the future scale-up of the GS adsorption process was studied systematically. Simulation of the MTZ behavior under various operation conditions in a packed adsorption column enabled the predictions of breakthrough curves of GS for the mesoporous adsorbent...

Novel anti-inflammatory target of geniposide: Inhibiting Itgβ1/Ras-Erk1/2 signal pathway via the miRNA-124a in rheumatoid arthritis synovial fibroblasts.

Geniposide (GE) is an active component isolated from the fruit of Gardenia jasminoides Ellis that has anti-inflammatory and other pharmacological effects; however, the underlying mechanism of GE action has not been elucidated in rheumatoid arthritis (RA). Previous studies have shown that GE plays a therapeutic role in RA via regulation of the integrin beta 1 (Itgβ1)-mediated Ras-Erk1/2 signalling pathway. However, the specific mechanism of GE action on Itgβ1 has not been clarified. Recent evidence indicat...

Impact assessment of leaf pigments in selected landscape plants exposed to roadside dust.

Continuous addition of undesired effluents to the environment affects foliar surface of leaf, changes their morphology, stomata, photosynthetic pigments, and biochemical constituents which result in massive damage due to persistent nature of the pollutant. In persistent hostile environment, plants fail to grow and develop, and the effects are often extensive. In current study, landscape plants were exposed to different levels of road dust to analyze the effect on various photosynthetic pigments. Dry roadsid...
