HPLC-NMR analysis of phenylphenalenones and a stilbene from Anigozanthos flavidus1Dedicated to Professor Günter Adam on the occasion of his sixty-fifth birthday.1

Natural stilbenoids: distribution in the plant kingdom and chemotaxonomic interest in Vitaceae

“…31,94 The phenylphenalenone-type natural products, a kind of phytoalexin, common in Haemodoraceae 125 and also discovered in another Commelinales family, Pontederiaceae, 126 and Zingiberales, 127 can justify a possible apomorphy uniting. Similarly, it is interesting to note that anigopreissin A, a resveratrol dimer, has been identified only both in M. cavendishii 128 (Musaceae, Zingiberales) and in two Anigozanthos species, A. flavidus 129 and A. preissii 128 (Haemodoraceae, Commelinales) and could be also a chemotaxonomic marker. Finally, if the simple monomer resveratrol could be identified in several Poaceae genera, 3 stilbenes are rather known to be produced by Cyperaceae genera.…”

HPLC–NMR for tissue‐specific analysis of phenylphenalenone‐related compounds in Xiphidium caeruleum (Haemodoraceae)

“…However, HPLC-NMR has been a suitable tool for analyzing natural products in biosynthetic, 4 chemotaxonomic, 5 and enzymatic studies 6 as well. Increasing interest in ecological functions of secondary plant products has supported the development of techniques enabling the investigation of organ-, tissue-, and cell-specific distribution of natural products in the producing species.…”

Isolation and Structural Elucidation of Steroid Oligoglycosides from the StarfishAsteriasrubens by Means of Direct Online LC-NMR-MS Hyphenation and One- and Two-Dimensional NMR Investigations

“…Although LC-NMR [3] has frequently been used for analyses of mixtures of natural products during recent years, [4][5][6][7][8][9][10][11] this technique has not yet been applied to saponins in the molecular weight range of 1200-1400 a.m.u.…”
