atractylodes ovata/carbohydrate

A traditional herbal medicine, Atractylodes macrocephala Koidz. (AMK), has long been used as a digestive and tonic. Recent investigations have suggested its potential ability in stimulating immune responses, although a scientific basis for this activity has not yet been elucidated. Based on previous

Hot water extract (ALR-0) of rhizomes of Atractylodes lanceo DC. was fractionated into MeOH-soluble fraction (ALR-1), supernatant fraction of EtOH precipitation (ALR-3 + 4), and crude polysaccharide fraction (ALR-5). Among these fractions, only ALR-5 showed potent stimulating activity for

A neutral polysaccharide (ALP-1) and an acidic polysaccharide (ALP-3) were purified from Atractylodes lancea (Thunb.) DC. ALP-1 exhibited a linear backbone composed of (2 → 1)-linked β-d-fructofuranose. The backbone of ALP-3 was elucidated as →4)-GalAp-(1 → 3,4)-Rhap-(1→, and with branch chain

The effects of the endophytic fungus Gilmaniella sp. and its elicitor on the defense and metabolic responses of host plants Atractylodes lancea were investigated, in order to understand how to utilize endophytic fungi and their elicitor resources better. The results showed that the promotion effect

The fungal endophyte Gilmaniella sp. AL12 can establish a beneficial association with the medicinal herb Atractylodes lancea, and improve plant growth and sesquiterpenoids accumulation, which is termed "double promotion." Our previous studies have uncovered the underling

The bacterial endophyte Pseudomonas fluorescens ALEB7B significantly enhances photosynthate accumulations in Atractylodes lancea. These carbohydrates are preferentially used by the host plant to synthesize secondary metabolites, rather than to increase plant biomass accumulation. Mechanisms

In this work, a novel ion exchange stationary phase based on different generations of poly (amidoamine) dendrimers (PAMAM) was developed for the determination of inorganic anions and carbohydrates. Synthesis of the PAMAM was carried out with the polymerization reaction of ethylenediamine and methyl
