HBr-Reactive acids ofMalva sylvestris seed oil

Malva sylvestris seed oil contained 5.6% sterculic, 11.0% malvalic, 1.6% vernolic, 15.6% lauric, 6.6% myristic, 26.6% palmitic, 5.6% palmitoleic, a trace of stearic, 23.0% oleic and 4.0% linoleic acids. The co-occurrence of malvalic and sterculic acids was established by gas liquid chromatography (GLC) of the silver nitrate-methanol treated esters usingSterculia foetida esters as the reference standard. Co-occurrence of epoxy acid (vernolic acid) was confirmed withVernonia anthelmintica as the lipid standard.
