The close relationship among the families of the “core” Malvales, Malvaceae, Bombacaceae and Tiliaceae has been recognised since the beginnings of scientific plant systematics. A.P. De Candolle (1824) in his “Prodromus” treated them in direct sequence, and Elaeocarpaceae and Chlaenaceae followed immediately.

Mass spectra of methyl sterculate and malvalate and 1,2-dialkylcyclopropenes
Chemistry and Physics of Lipids, 1974Abstract The mass spectra of 1,2-dipropyl-, 1,2-dipentyl-, 1,2-dihexyl-, 1,2-diheptyl-, and 1,2-dioctyl-cyclopropene, methyl malvalate, methyl sterculate, malvalyl alcohol, 1,2-dipropyl-, 1,2-dipentyl-, and 1,2-dihexylcyclopropene-3-carboxylic acid, and methyl-9,10-(carbethoxymethano)-9-octadecenoate are presented.

Separation of methyl malvalate from methyl sterculate
Journal of the American Oil Chemists' Society, 1981AbstractMethyl malvalate and sterculate, labile and differing by a single methylene, are difficult to separate completely. They have been separated in our laboratory by high vacuum spinning band distillation. Each of these fatty esters has been prepared completely free of the other.

Syntheses of C-14 labeled methyl malvalates
Chemistry and Physics of Lipids, 1971Abstract Malvalic acid, the principle cyclopropene acid in cottonseed oil, has been synthesized with carbon-14 at the 1-position, at the ring methano-position, and at the 10-position. A method for reaching malvalic-9- 14 C acid has also been worked out.

New Ring Opening Oxidation of Methyl Sterculate and Malvalate
Chemistry Letters, 1990Abstract Air oxidation of cyclopropane fatty acid methyl esters, methyl sterculate and malvalate, resulted in the cleavage of cyclopropene ring, respectively, to afford a pair of conjugated enones containing a terminal methylene group.

Systematic Botany, 2017
Abstract Cochlospermaceae (Malvales) is a small family of two genera, Amoreuxia and Cochlospermum. Cochlospermum has a pantropical distribution with species present in Mexico, Central and South America, the West Indies, Africa, India, Southeast Asia, and northern Australia, whereas Amoreuxia has a more restricted distribution in the Americas. Amoreuxia

Wood Anatomy of Craigia (Malvales) from Southeastern Yunnan, China
IAWA Journal, 2006Wood anatomy of Craigia W.W. Sm. & W.E. Evans (Malvaceae s.l.), a tree endemic to China and Vietnam, is described in order to provide new characters for assessing its affinities relative to other malvalean genera. Craigia has very low-density wood, with abundant diffuse-in-aggregate axial parenchyma and tile cells of the Pterospermum type in the ...

CHROMOSOME NUMBERS AND KARYOTYPE STUDIES OF FEW MEMBERS OF MALVALES
2019Chromosome numbers and karyomorphological data are essential in selecting the suitable species for plant breeding programmes, resolving taxonomic confusions, tracing the evolutionary tendencies and evolving ployploid varieties. In this study, we analysed the karyotype analysis of five malvales species, viz., Sida rhombifolia, Sida spinosa, Sida acuta ...

The Mass Spectra of the Picolinyl Ester Derivatives of Malvalic and Sterculic Acid
Lipid / Fett, 1994AbstractThe mass spectra of the picolinyl derivatives of two natural occurring cyclopropenoid fatty acids (malvalic and sterculic acid) showed, besides the typical peaks for picolinyl derivatives, a characteristic gap of 66 amu between the two allylic positions of the ring system. This phenomenon could be used for the determination of the ring position

Eriolaena hookeriana seed oil: A rich source of malvalic acid
Chemistry and Physics of Lipids, 1979Abstract The seed oil of Eriolaena hookeriana (Sterculiaceae) contains malvalic (25.8%) and sterculic (6.0%) acids in addition to normal fatty acids. Eriolaena hookeriana is the second known species of the Sterculiaceae plant family whose seed oil contains more malvalic acid than sterculic acid.
