Abstract
An arabinogalactan of mean M(r) 2.2 x 10(6) has been isolated from the dried stems of Tinospora cordifolia and examined by methylation analysis, partial hydrolysis and carboxyl reduction. Purified polysaccharide showed polyclonal mitogenic activity against B-cells, their proliferation did not require macrophages.
摘要
已从心叶青牛胆干燥茎中分离出平均分子量为2.2×10⁶的阿拉伯半乳聚糖，并通过甲基化分析、部分水解和羧基还原进行了研究。纯化的多糖对B细胞显示出多克隆促有丝分裂活性，其增殖不需要巨噬细胞。
