Four new triterpene glycosides from Thalictrum squarrosum.
Four new triterpene glycosides were isolated from the dried aerial parts of Thalictrum squarrosum (Ranunculaceae). They were designated as squarroside I, being a cycloartane-type glycoside, and squarrosides II, III and IV, being oleanene-type glycosides. Their structures were established by using two dimensional (2D) NMR techniques.
متن کاملDetermination of bioactive isoquinoline alkaloids in Thalictrum reniforme Wallich and Thalictrum neurocarpum Royale using ultra performance liquid chromatography with hybrid triple quadrupole linear ion trap mass spectrometer
Thalictrum is a well recognised genus of medicinal plants. It is widely distributed in temperate and tropical habitats of India. Alkaloid isomers from Thalictrum are reported to exhibit various pharmacological activities like antiamebic, antimicrobial, antitumour and antiviral. Thalictrum reniforme Wallich and Thalictrum neurocarpum Royale are very less studied species of the genera. In present...
متن کاملThalictricoside, a new phenolic compound from Thalictrum orientale.
From the underground parts of Thalictrum orientale Boiss., a new phenolic compound 1 was isolated in addition to one known cyanoglycoside, lithospermoside (2). For the structure elucidation of all compounds, 1D- and 2D-NMR techniques (DEPT, COSY, HMBC, HSQC) and MS (HR-MALDI) were used. The structure of the new compound was established as 2-(4'-hydroxyphenyl)-nitroethane-4'-O-[beta-xylopyranosy...
متن کاملDolabellane diterpene and three cycloartane glycosides from Thalictrum squarrosum.
A new dolabellane diterpene glycoside, named squoside A, and three new cycloartane glycosides, named squarrosides V, VI, and VII, have been isolated from the dried aerial parts of Thalictrum squarrosum (Ranunculaceae). Their structures were determined by two dimensional (2D) NMR spectroscopic analysis and chemical evidence.
متن کاملمطالعه مروری جنس . Thalictrum L در ایران
جنس . Thalictrum L بر اساس بررسی منابع و نمونه های هرباریومی و همچنین نمونه های جمع آوری شده توسط مؤلفین مورد بازبینی قرار گرفت. با استفاده از آنالیز تجزیه به عامل ها و تعیین متغیرترین صفات یک کلید شناسایی برای گونه های پذیرفته شده در ایران تهیه شد. علاوه بر آن بر اساس 29 صفت کمی و کیفی ریخت شناسی، آنالیز خوشه ای با استفاده از روش وارد جهت تعیین جایگاه گونه ها در گروه های گونه ای انجام شد. علاو...
