Cytological Studies on Monnina

Feddes Repertorium, 1967
AbstractThree species of Monnina have been studied cytologically for the first time. The following chromosome numbers were found, M. brachystachya n = 9 and 2n = 18; M. dictyocarpa 2n = 40; M. rusbyi n = 10 and 2n = 20. Evolutionary trends in the genus are discussed.

Fatty Acids of Monnina emarginata Seed Oil

Lipids and Lipid Metabolism, 1970
Abstract The oil of Monnina emarginata St. Hill seed contains three unusual acids, 13 l -hydroxy-cis-9,trans-11-octadecadienoic [(S)-coriolic] acid (30% by weight), 13-oxo-(trans-9,(trans-11-octadecadienoic (0.9%) and 13-oxo-(trans-9-octadecenoic acids (0.2%), in addition to common long-chain fatty acids.

Biphenyls and a Xanthone From Monnina Sylvatica

Phytochemistry, 1992
Abstract Two novel biphenyls, 3′-hydroxy-4′,5-dimethoxy-3,4-methylenedioxybiphenyl and 3′,4′,5-trimethoxy-3,4-methylenedioxybiphenyl, and a known xanthone were isolated from the roots of Monnina sylvatica . The structures of the isolates were established by spectroscopic methods (UV, mass spewometry, 1 H and 13 CNMR, including homonuclear NOE ...

A Revision of the Venezuelan Species of Monnina

Brittonia, 1957
In continuation of his study of the genus Monnina (Polygalaceae), the writer has examined all the readily available Venezuelan specimens of it in several American herbaria, and the present paper summarizes what is known of the genus in Venezuela. On the basis of the material seen, there are ten species of the genus in this country, a somewhat smaller ...

Systematics of Monnina (Polygalaceae)

2021
Endemic to the Neotropics, Monnina is the second largest genus in Polygalaceae, yet little is known about its phylogenetic history and morphological character evolution. Because Monnina demonstrates a great deal of morphological variability among species, a phylogenetic study was conducted to resolve where characters important in the diversification of

Glycerides of Monnina emarginata seed oil

Biochimica et Biophysica Acta (BBA) - Lipids and Lipid Metabolism, 1970
Abstract The seed oil of Monnina emarginata St. Hill was divided by thin-layer chromatography into fractions of differing polarity. The least polar fraction (63%) contained tri-acid and tetra-acid glycerides in a 1 : 2 mole ratio, as well as the lactone of (S)-13-hydroxy-cis-9, trans-II-octadecadienoic acid [(S)-coriolic acid]. The notable structural

Monnina (Polygalaceae), a New World monophyletic genus full of contrasts

Botanical Journal of the Linnean Society, 2023
Abstract Endemic to the Neotropics, Monnina is the second largest genus of Polygalaceae, yet little is known about its phylogenetic history, biogeography, and morphological character evolution. To address these knowledge gaps, we conducted Bayesian and maximum likelihood (ML) analyses of nuclear ITS and plastid trnL–F regions to test the
