pinus parviflora/polysaccharide

Hot water extract of pine cone (PCE) of Pinus parviflora Sieb. et Zucc. dose-dependently suppressed both solid and ascites tumor cells transplanted into various mice. Acidic polysaccharides of PCE significantly increased the survival time of mice bearing ascites tumor cells, and activity increased

Pretreatment with two distinct antitumor substances extracted from pine cone of Pinus parviflora Sieb. et Zucc. protected mice from the lethal effects of E. coli infection. Intraperitoneal administration of these fractions transiently induced differentiation-inducing factor (DIF) with a peak at

Pretreatment with two distinct lignin-related antitumor substances extracted from pine cone of Pinus parviflora Sieb. et Zucc. protected infant mice from Hymenolepis nana (Cestoda) infection. Subcutaneous administration of these fractions (10 mg/kg) to 1 week old mice evoked strong protective

The anti-influenza virus activity of polysaccharides and other high molecular weight fractions from pine cone extract (PCE) of Pinus parviflora Sieb. et Zucc. was investigated. None of the fractions affected the growth of MDCK cells. The acidic PCE substances markedly suppressed the growth of the

An acidic pine cone extract, Fr. V. of Pinus parviflora Sieb. et Zucc. significantly stimulated DNA synthesis of isolated splenocytes from both mice and rats, but only marginally affected the DNA synthesis of leukemic cell lines. The maximum stimulation level attained by Fr. V slightly exceeded that

A variety of tannin and lignin-related compounds were compared for their ability to modify the ascorbyl radical intensity of sodium ascorbate. Hot-water extracts prepared from green tea, black tea and pine cone (Pinus parviflora Sieb. et Zucc.), and various wines potently scavenged ascorbyl radical
