Characterization and antitumor activity of pollen polysaccharide

Extraction of polysaccharide from Ganoderma lucidum and its immune enhancement activity

“…The corrective clearance index of UCP was no significantly increased comparing with the model control group. This result is disagreement with that of Yang et al and they found that pollen polysaccharides could increase the ability of lymphocyte proliferation of tumor-bearing mice in a dose dependent manner [22]. This may be that the monocyte factor has decreased to the normal level after 4 weeks gastric feed.…”

“…Tumor cell elimination is known to be mediated in part by the cytotoxic activity of Natural killer (NK) cells [22]. As shown in Table 5, compared with the normal control group, NK cells killing activity of the model control group was significantly decreased (P < 0.05), showing that the immunocompromised model was successfully built.…”

“…The test of carbon clearance was carried out according to the method of Yang et al [22]. The mice were injected intraperitoneally with dexamethasone (50 mg/kg) to cause an immunocompromised model on the 27th and 29th days of gastric feed while the normal control group was injected with an equal volume of normal saline (NS).…”

Composition and antioxidant activity of the polysaccharides from cultivated Saussurea involucrata

“…Recently, polysaccharides from medicinal plants have provoked high-level research attention in view of its potential biological activities such as antitumor, antiviral and immunological activities [7][8][9]. Chemical constituents and bioactivities between tissue cultures and wild plants of S. involucrata have attracted great interest among researchers [10].…”

Cell proliferative effect of polyxyloses extracted from the rhizomes of wild turmeric,Curcuma aromatica

“…Z. Tang & S. J. Cheng (Orchidaceae) stems (Zha et al, 2007) have immunostimulating activities. Finally, polysaccharides extracted from the pollen of Brassica napus L. (Brassicaceae) and Phoenix dactylifera L. (Arecaceae) (Yang et al, 2007a(Yang et al, , 2007b have anticancer and antitumor activities, respectively.…”
