Extraction of polysaccharides and its antitumor activity on Magnolia kwangsiensis Figlar & Noot.

L‐asparaginase isolated fromStreptomyces ansochromogenespromotes Th1 profile and activatesCD8+T cells in humanPBMC: anin vitroinvestigation

“…This concentration was chosen based on a recent study by Zheng et al . () that recommended choosing lower concentrations when antitumour drugs are investigated in in vitro assays.…”

“…After the cytotoxicity assay, the L-asparaginase concentration used to stimulate human PBMC in 24-h cultures was 12Á5 lg ml À1 . This concentration was chosen based on a recent study by Zheng et al (2016) that recommended choosing lower concentrations when antitumour drugs are investigated in in vitro assays.…”

Optimization for ultrasound-assisted extraction of polysaccharides with chemical composition and antioxidant activity from the Artemisia sphaerocephala Krasch seeds

“…Hot-water extraction (HWE) is a popular method for polysaccharides extraction reported in the vast majority of polysaccharides study [6][7][8]. However, HWE is usually associated with higher temperature and longer extraction time but lower extraction efficiency [9].…”

Extraction and Antioxidant Activities of Magnolia kwangsiensisFiglar & Noot. Leaf Polyphenols

“…[2] The plant is a first-grade State Protection plant in China, and only locates in the southwestern region of China. [5] Polyphenols are secondary plant metabolites with high antioxidant capacity, which have many beneficial implications on human health, such as the protective action against cardiovascular diseases, [6] chronic degenerative diseases [7] and cancer, [8] and have been a popular research area in recent years. Recently, more and more attention is paid on its planting protection, development and utilization.…”

“…However, studies on the chemical composition of the M. kwangsiensis leaf only involved in essential oil [3,4] and polysaccharides. [5] Polyphenols are secondary plant metabolites with high antioxidant capacity, which have many beneficial implications on human health, such as the protective action against cardiovascular diseases, [6] chronic degenerative diseases [7] and cancer, [8] and have been a popular research area in recent years. [9,10] Literatures [11,12] about polyphenols of other Magnolia plants showed that these plants contained considerable amounts of polyphenols, which had remarkable antioxidant activities.…”
