“…Modern pharmacological studies show that polysaccharides from the traditional Chinese medicine have anti-tumor, immunity enhancing, anti-inflammatory, and anti-oxidation effects as well as helping to regulate the intestinal microenvironment ( 25 – 29 ). It is shown that polysaccharide can easily be depolymerized during the extraction process, and starch can easily be gelatinized and denaturalized ( 30 ).…”

“…Furthermore, we found that the extraction of polysaccharides in soups prepared by the boiling processes that used an additive (processes 2, 3, 4, and 5) was generally better than when using only pure water (daily process and process 1), regardless of the type of additive used. Modern pharmacological studies show that polysaccharides from the traditional Chinese medicine have anti-tumor, immunity enhancing, anti-inflammatory, and antioxidation effects as well as helping to regulate the intestinal microenvironment (25)(26)(27)(28)(29). It is shown that polysaccharide can easily be depolymerized during the extraction process, and starch can easily be gelatinized and denaturalized (30).…”

Lilii Bulbus, an edible Chinese herbal medicine, has a long history in medicine. However, research on effectively boiling Lilii Bulbus is rare. To make the more nutritious Lilii Bulbus soup, the optimized boiling process, using an alternate heating mode by decoction pot carrying a mixture of water and Chinese liquor at the ration of 9:1, was established in this study. Compared to the soup prepared by the daily process, the polysaccharide amount improved by 54%, and the total heavy metals decreased by 33.5% using the optimized boiling process. In addition, the total saponins at 34.3 μg/g were determined in the soup prepared by the optimized process. Meanwhile, the colchicine content in the boiled Lilii Bulbus soup was undetectable using the optimized process. This research performs an optimized boiling process for making Lilii Bulbus soup, and provides a reference for generating high commercial value from Lilii Bulbus soup in the future.

“…At present, solvent (e.g., water) extraction, physical-assisted (ultrasonic, microwave, etc.) extraction, and enzymatic hydrolysis extraction had become the main extraction methods of GP ( 29 ). There were many related reports before, but there was a less in-depth exploration of structural analysis.…”

The sulfated polysaccharide was isolated from the purified G. lemaneiformis polysaccharide (PGP), and its property in delaying H2O2-induced 2BS cellular senescence was studied. The results showed that PGP was a linear polysaccharide containing alternating α-(1 → 3)- and β-(1 → 4)-galactopyranose units. Most of the sulfate groups are at C6 of the -(1 → 4)-α-D-Galp, and a small part of them are at C3 and C6. PGP pretreatment could decrease SA-β-gal-positive cells and prevent the formation of senescence-associated heterochromatic foci (SAHF) induced by H2O2 in a dose-dependent manner. It is speculated that PGP may delay aging by downregulating the expression of p21 and p53 genes. The finding provides new insights into the beneficial role of G. lemaneiformis polysaccharide (GP) on retarding senescence process.

“…G. lemaneiformis is a kind of economic red algae, rich in polysaccharide, phycobiliprotein, pigment, mineral and other nutrients and active components, which plays essential roles in hypoglycemic, hypolipidemic, anti-bacteria, anti-cancer and other physiological activities ( Chen et al, 2010 , Chen et al, 2021 , Fan et al, 2012 , Huang et al, 2019 , Huang et al, 2020 , Long et al, 2021a , Sun et al, 2018 , Wang et al, 2019 ). Li et al (2020) revealed that G. lemaneiformis polysaccharide observably regulated the lipid metabolism and accelerated free fatty acid oxidation.…”
