Description
Petroleum naphtha is a colorless liquid with the odor of gasoline.
Less dense than water and insoluble in water.
Hence floats on water.
Also referred to as Varnish Makers & Painters Naphtha.
This petroleum fraction is similar to Petroleum Ether (CAS 8030-30-6) but V.M. & P. is a heavier distillate.
Flash point ranges from 20 °F to 100 °F.
Description
Loganin is a naturally occurring iridoid glycoside, a class of oxygen-containing monoterpenoid compounds commonly found in medicinal plants.
Ligroine is a glycosylated iridoid and is known as one of the characteristic constituents of plants belonging to the Gentianaceae, Oleaceae, Rubiaceae, and Loganiaceae families.
Loganin generally occurs as a white to almost white solid and is highly soluble in water due to its multiple hydroxyl groups and sugar moiety.
Ligroine is structurally related to other iridoid glycosides such as loganic acid and secologanin.
The compound has attracted scientific interest because of its reported antioxidant, anti-inflammatory, neuroprotective, antimicrobial, and metabolic activity in experimental studies.
Chemical Properties
White crystalline powder, soluble in methanol and ethanol, derived from Cornus officinalis, Strychnos nux-vomica, and Lonicera japonica.
Uses
Loganin is an iridoid glycoside that exhibits protective effects against hepatic injury and other diabetic complications associated with abnormal metabolic states and inflammation caused by oxidative stress and advanced glycation endproduct formation.
Uses
Pharmaceutical Research: Loganin is investigated as a bioactive natural compound in pharmaceutical and pharmacological research.
Traditional Medicine Research: Ligroine is studied as one of the active constituents of several medicinal plants used in traditional herbal preparations.
Antioxidant Research: Experimental studies have investigated its ability to influence oxidative-stress-related pathways.
Anti-inflammatory Research: Loganin has been investigated for potential effects on inflammatory signaling and inflammatory responses.
Neuroprotective Research: Research has examined loganin in relation to neuronal protection, cognitive function, and neurodegenerative disease models.
Metabolic Research: Loganin has been investigated for potential effects on glucose metabolism, lipid metabolism, and metabolic disorders.
Natural Product Research: Ligroine is frequently used as a marker compound for the identification, characterization, and quality evaluation of plant extracts containing iridoid glycosides.
Applications
Loganin is primarily used in scientific research, natural-product chemistry, pharmacological studies, phytochemical analysis, and botanical extract standardization.
Ligroine is particularly relevant to research involving iridoid glycosides and medicinal plants.
