Strictosidine beta-D-glucosidase (SGD) is an enzyme involved in the biosynthesis of terpenoid indole alkaloids (TIAs) by converting strictosidine to cathenamine. The biosynthetic pathway toward strictosidine is thought to be similar in all TIA-producing plants. Somewhere downstream of strictosidine
Oleocellosis is a serious physiological disorder in citrus fruit that mainly results in appearance and quality deterioration. It has been well established that the occurrence of oleocellosis is highly correlated with the release of peel oil from citrus fruit, while there is little information on the
Geraniol 10-hydroxylase (G10H) is a cytochrome P450 monooxygenase involved in the biosynthesis of iridoid monoterpenoids and several classes of monoterpenoid alkaloids found in a diverse range of plant species. Catharanthus roseus (Madagascar periwinkle) contains monoterpenoid indole alkaloids,
Terpenoids, one of the major components of essential oils, are known to exert potent antifungal activity against yeast Saccharomyces cerevisiae. They have been the subject of a considerable number of investigations that uncovered extensive pharmacological properties, including antifungal and
Recent studies suggested that the non-familiar form of Alzheimer's disease (AD) could be consequence of metabolic syndrome and neuroinflammation. Elettaria cardamomum extract (EC) has exhibited antidiabetic, antioxidant and anti-inflammatory properties. This research was conducted to BACKGROUND
Andaliman (
Zanthoxylum acanthopodium) is a spice traditional Northen Sumatera, Indonesia and these fruits contain alkaloids, steroids and
terpenoids. Extra Virgin Olive Oil (EVOO) contains antioxidants. Combination of this plant have activities to reduce
The novel tricyclic-terpenoid type cannabinoid, HU-211, was tested in gerbils and rats for protection against the effects of cerebral ischemia. Our transient ischemic models in gerbils and rats are based on the protection afforded against the lethal effects of global ischemia. HU-211 gave over 30%
The need for environmentally friendly practices in animal husbandry, in conjunction with the reduction of the use of synthetic chemicals, leads us to reconsider our agricultural production systems. In that context, grassland secondary metabolites (GSMs) could offer an alternative way to support to
We investigated that the long-term consumption of the water (KME-W) and 70% ethanol (KME-E) mistletoe extracts had antidiabetic activities in partial pancreatectomized (Px) rats. Px rats were provided with a high-fat diet containing 0.6% KME-E, 0.6% KME-W, and 0.6% dextrin (control) for 8 weeks. As
Catharanthus roseus (L.) G. Don produces a number of biologically active terpenoid indole alkaloids via a complex terpenoid indole alkaloid biosynthetic pathway. The final dimerization step of this pathway, leading to the synthesis of a dimeric alkaloid, vinblastine, was demonstrated to be catalyzed
A study was made of the ultrastructure of root cap meristematic cells in the seedlings of Cucumis sativus L., whose growth was inhibited by the action of 2-acetyl-4-metylcyclopent-4-en-1,3-dione (AMCD). It is shown that the treatment of seeds by this substance at a concentration of 100 microg/ml
The conifer Picea abies (Norway spruce) employs terpenoid-based oleoresins as part of its constitutive and induced defense responses to herbivores and pathogens. The isoprenyl diphosphate synthases are branch-point enzymes of terpenoid biosynthesis leading to the various terpene classes. We isolated
Squalene is a terpenoid found in human skin surface lipids (SSLs) and foods that possesses beneficial properties. However, since oxidation of squalene causes various complications, it is necessary to identify the mechanisms by which squalene is oxidized. In this study, we aimed to determine the
Parkinson's disease (PD) is a well-known neurodegenerative disorder characterized by dopaminergic (DA) neuron loss and α-synuclein aggregation. Recent study revealed that the extracts from sea cucumber, Holothuroidea spp., exhibited neuroprotective and lifespan extension effects in Caenorhabditis
Tea plant (Camellia sinensis (L) O. Kuntze) respond to herbivore attack through large changes in defense related metabolism and gene expression. Ectropis oblique (Prout) is one of the most devastating insects that feed on tea leaves and tender buds, which can cause severe production loss and
