腑实验证明用含有LBP一4 50 mg一1、100 mg·L-l、200mg.L'，和400mg·L-l的培养液培养人肝癌细胞邻Y一7703可显著抑制其增殖；细胞形态学观察发现LBP一4可诱导那Y一7703细胞发生凋亡，使细胞凋亡指数显著提高。

The monosaccharides in LBP-4 identified by GC were xylose , galactose , mannose , Rhamnose , glucose and arabinose with the molar ratio of 4. 45: 1. 20: 1. 0: 0.98: 0.90: 0.85. The content of calcium, magnesium, zinc and iron in LBP-4a were 127. 9070mg·g〓, 32. 3953mg·g〓, 0.3845mg·g〓 and 0.2930mg·g〓, respectively. The content of galacturnic acid in LBP-4a was 55. 45% while the content of protein is 3. 80%. According to IR spectra, it contains -COOH group,-NH- roup,-OH group,-NH〓 group and β-D-glucose. The backbone of sugar residues chain in LBP-4a were contained 1→6 indican bond according to periodate oxidation and the results of β-elimination reaction indicated that the chain of polysaccharides and protein were connected by O-linked chemical bond. The photograph of LBP-4a got by laser scanning confocal microscope and scanning electron microscope showed that the LBP-4a combined both with each other and with itself in its crystalloid. The crystalloid was flake and anisotropic.

由LBP-4a的红外光谱图知：LBP-4a中含有-COOH、-OH和-NH〓或-NH-基团，糖链中含有β-D-吡喃葡萄糖；高碘酸氧化实验知LBP-4a糖链中不具有连二羟基和连三羟基结构的单糖残基：具有连二羟基结构的单糖残基：具有连三羟基结构的单糖残基=57.0：16.2：1，六碳糖残基的连接中含有1→6连接的糖苷键；通过β消去反应证明LBP-4a中多糖链和氨基酸间为-O-型连接；由激光扫描共聚焦显微镜和扫描电镜对LBP-4a结晶观察结果推测：LBP-4a结晶中同时存在分子间和分子内结合的现象，LBP-4a分子相互结合时，并不是无规则的相互缠绕形成无规线团结构，而是形成片层结构，并且LBP-4a结晶可能具有各向异性的性质。
