background: glycosidases profusion in male reproductive fluids suggests a possible relationship with sperm function. although hexosaminidase (hex) is the most active glycosidase in epididymal fluid and seminal plasma, as well as in spermatozoa, glucosidase is considered a marker for epididymal function and azoospermia. objective: the aim of this study was to determine hex activity in seminal pl...

In this paper, the biosynthesis process of phenolic compounds in plants is summarized, which include the shikimate, pentose phosphate and phenylpropanoid pathways. Plant phenolic compounds can act as antioxidants, structural polymers (lignin), attractants (flavonoids and carotenoids), UV screens (flavonoids), signal compounds (salicylic acid, flavonoids) and defense response chemicals (tannins,...

the side effects associated with the usage of synthetic antidiabetic drugs make it imperative to search for alternative drugs from medicinal plants. therefore, this study was aimed at evaluating the α-amylase and α-glucosidase inhibitory potential of calotropis procera leaf, as well as its possible mode of inhibiting these enzymes. acetone, aqueous and ethanolic extracts of c. procera leaf was ...

Myrcia is one of the largest genera of the economically important family Myrtaceae. Some of the species are used in folk medicine, such as a group known as "pedra-hume-caá" or "pedra-ume-caá" or "insulina vegetal" (insulin plant) that it is used for the treatment of diabetes. The species are an important source of essential oils, and most of the chemical studies on Myrcia describe the chemical ...

This study was done to produce γ-aminobutyric acid (GABA) from wild yeast as well as investigate its anti-hyperglycemic effects. Among ten GABA-producing yeast strains, Pichia silvicola UL6-1 and Sporobolomyces carnicolor 402-JB-1 produced high GABA concentration of 134.4 µg/mL and 179.2 µg/mL, respectively. P. silvicola UL6-1 showed a maximum GABA yield of 136.5 µg/mL and 200.8 µg/mL from S. c...

Minor ginsenosides, such as compound K, Rg₃(S), which can be produced by deglycosylation of ginsenosides Rb₁, showed strong anti-cancer effects. However, the anticancer effects of gypenoside LXXV, which is one of the deglycosylated shapes of ginsenoside Rb₁, is still unknown due to the rarity of its content in plants. Here, we cloned and characterized a novel ginsenoside-transforming β-glucosid...

Blackberry and pear are rich in human health protective phenolic bioactives with high antioxidant activity. These fruits relevant dietary targets to counter chronic oxidative stress-linked diseases, such as type 2 diabetes (T2D). Due perishability, the bioactive qualities of deteriorate during postharvest storage processing. By improving stability bioavailability nutritionally post-harvest stag...

Aim: To confirm their use in the management of diabetes and to determine numerous phytochemicals present that may be connected active performance plants, fractionated extracts Leptadenia hastata Entada africana were subjected an vitro experiment. Material methods: The plant leaves dried, pulverized with a Sumeet CM/L 2128945 grinder, particle size was 45.85 ?m extracted methanol. crude using 30...

The gene encoding for an extremely thermostable oligo-1,6-glucosidase from Bacillus thermoglucosidasius KP1006 (DSM2542, obligate thermophile) was sequenced. The amino acid sequence deduced from the nucleotide sequence of the gene (1686 base pairs) corresponded to a protein of 562 amino acid residues with a Mr of 66,502. Its predicted amino acid composition, Mr, and N-terminal sequence of 12 re...
