从土参(Smilax Riparia)的根茎和根中分离得到两个新的新青蒿素苷元，从中国的根茎和根中分离得到一个新的异青蒿素皂苷。通过光谱分析和水解法相结合，然后进行光谱分析和色谱分析，确定了它们的结构。还分离和鉴定了几个已知的皂苷。测定了皂苷对cAMP磷酸二酯酶的抑制活性。
Two new neotigogenin glycosides were isolated from the rhizomes and roots of Smilax riparia and a new isonarthogenin glycoside from those of S. china. The structures were elucidated by a combination of spectroscopic analysis and hydrolysis followed by spectral and chromatographic analysis. Several known saponins were also isolated and identified. The inhibitory activity of the saponins on cAMP phosphodiesterase was examined.
