Variations of Konjac glucomannan (KGM) from Amorphophallus konjac and its refined powder in China
Food Hydrocolloids, 2004Abstract Konjac glucomannan (KGM) is a water-soluble dietary fiber extracted from tubers of Amorphophallus konjac native to China. It has a low caloric content and is a soluble dietary fiber, used in foods and medicine ingredients. This paper reports changes of KGM from Amorphophallus konjac native in the southern part of China to KGM obtained in

A cell‐block preparation using Glucomannan extracted from Amorphophallus konjac
Diagnostic Cytopathology, 2010AbstractTo evaluate a cell‐block preparation using glucomannan, which was extracted from Amorphophallus konjac. Ten specimens were centrifuged at 1,500 rpm for 5 minutes, the supernatant was removed; the remnant after the preparation of smear specimens for routine cytological examination was fixed with 20% formalin.

Amorphophallus konjacanthracnose caused byColletotrichum siamensein China
Journal of Applied Microbiology, 2019Amorphophallus konjac is an important commercial crop grown in China because it is the only plant species which is rich in glucomannan concentration. Recently, an outbreak of anthracnose (incidence ranging from 10-15%) was observed in a field survey conducted from June to August 2018. This study aims to identify the causal agent of A.

Obesity Medicine, 2021
Abstract This review outlines the positive effects of konjac (Amorphophallus konjac K. Koch) and it polysaccharide glucomannan on human health, on fat metabolism and obesity. The available data demonstrate, that both konjac and glucomannan can reduce fat storage via several extra- and intracellular mechanisms.

Carbohydrate Polymers, 2012
Abstract Here we present a comparison of commonly used methodologies for the extraction and quantification of konjac glucomannan (KGM). Compositional analysis showed that the purified konjac flour (PKF) produced using a modified extraction procedure contained 92% glucomannan, with a weight average molecular weight ( M w ), polydispersity index (PDI)

Molecular detection of Pectobacterium species causing soft rot of Amorphophallus konjac
World Journal of Microbiology and Biotechnology, 2010Soft rot disease of Amorphophallus konjac is caused by Pectobacterium species. Infected corms are considered a primary and important source of inocula. Based on the 16S rDNA sequences of the soft rot pathogens, one pair of specific primers was designed to identify the soft rot disease by real-time PCR and the other two were used to identify the ...

Effect of Amorphophallus Konjac oligosaccharides on STZ-induced diabetes model of isolated islets
Life Sciences, 2002Three oligosaccharide fractions from the root of Amorphophallus Konjac, which was reported with hypoglycemic effects on diabetes subjects, were isolated and studied using the STZ-treated diabetes model. Among them, one fraction named as KOS-A, was found with nitric oxide (NO(*)) free radical regulation effect, while the other two were not.
