A novel alkenoic acid ester and a new benzophenone from Ranunculus ternatus

A novel alkenoic acid ester, （E）-4-hydroxy-dodec-2-enedioic acid-12-O-methyl ester and a new benzophenone, ethyl （S）-3-[2- （3,4-dihydroxybenzoyl）-4,5-dihydroxyphenyl]-2-hydroxypropanoate, together with a known compound, （E）-4-hydroxy-dodec-2- enedioic acids were isolated from the roots of Ranunculus ternatus. Their structures were elucidated by spectroscopic methods.

Two New Glycosides from the Roots of Ranunculus ternatus

Two new glycosides named as ternatoside A 1 and ternatoside B 2 were isolated from the roots of Ranunculus ternatus, the structures were determined by 1D and 2D NMR, ESI-MS techniques, and chemical methods.

猫爪草化学成分及药理作用研究进展

猫爪草(Ranunculus ternatus Thunb.)是20世纪50年代新发现的草药,药用历史较短,但因其具有明显的抗结核和抗肿瘤作用而受到许多学者的关注。随着猫爪草化学成分和药理作用研究的深入,了解到猫爪草具有解毒、消肿散结、祛痰的较好疗效,被广泛应用于甲状腺结节、甲状腺肿、结核、咽炎等疾病的治疗。猫爪草的主要化学成分有多糖类、黄酮类、苷类及有机酸、挥发油,具有抗肿瘤、抗结核等作用。对猫爪草的化学成分、药理作用及新型杂环化合物进行综述,旨在为猫爪草的进一步研究提供参考。
