Arecoline is the effective ingredient of bing lang's helminthic effect. It could paralyze the whole body onload="highlight();" of pork tapeworm. It could only paralyze the cephalomere and immature proglottis of taenia saginata. In vitro tests showed that it also had paralyzing effect on threadworm. It could poison ascaris.

1:1 water immersion of bing lang had inhibitory effect on some dermatomyces to different degrees. The anti-viral effect of bing lang was related to its tannin. Its decoction and water immersion had inhibitory effect on some strains of influenza type A virus.

Arecoline had similar effects to pilocarpine. It could excite M-cholinergic receptor., led to the increase of gland secretions, contractions of bronchia, decrease of heart rate, dilation of blood vessel and lowering blood pressure. Used as eye drop, it could decrease the pupils. It could also increase the intestinal peristalsis.

Polyphenolic substance obtained from bing lang had obvious inhibitory effect on Ehrlich carcinoma, it had medium cytoxic effect on Hela cells.

Inhibitory effect of bupleuri radix saponins on adhesion of some solid tumor cells and relation to hemolytic action: screening of 232 herbal drugs for anti-cell adhesion.

Among 232 herbal drugs tested, six showed a remarkable anti-cell adhesive activity, and the extract from the roots of Bupleurum falcatum (Umbelliferae), the semen of Psorala corylifolia (Leguminosae), and the semen of Areca catechu (Palmae) showed an anti-cell adhesive action at non-cytotoxic concentrations. Saikosaponins-a, d and e, isolated from the roots of Bupleurum falcatum, exhibited a potent anti-cell adhesive activity and a strong hemolytic action. In a structure-activity relationship for both activities, it seems that a sugar moiety and an ether linkage between C-13 and C-28 are required for good bioactivities. In addition, saikosaponin d with a beta-hydroxy group at C-16 was more potent than saikosaponin a possessing an alpha-hydroxy group. Taken together, it is suggested that the mechanism for anti-cell adhesive activity of saikosaponin may resemble that for their hemolytic action.
