Fatty acid profile of seashore mallow (Kosteletzkya pentacarpos) seed oil and properties of the methyl esters

Abstract

In recent literature, seashore mallow (Kosteletzkya pentacarpos; also known previously as Kosteletzkya virginica) seed oil was reported as a potential alternative feedstock for biodiesel. In the present work, the fatty acid profile of K. pentacarpos is shown to correspond to that of other plants in the Malvaceae family by containing approximately 6% fatty acids with cyclic moieties, namely malvalic acid as well as dihydrosterculic acid. Previously determined properties of biodiesel from seashore mallow are discussed under the aspect of the fatty acid profile. The 1H‐ and 13C‐NMR spectra of K. pentacarpos methyl esters, which confirm the fatty acid profile, are also discussed. Practical applications: This article discusses the fatty acid profile of the seed oils of Kosteletzkya species. This is significant for evaluating potential applications of these oils. This is demonstrated by evaluating biodiesel fuel properties from the results. The seed oils of Kosteletzkya species contain malvalic acid and other acids with cyclic moieties.

Facing the challenge of sustainable bioenergy production: Could halophytes be part of the solution?

“…Another potential candidate for biofuel with positive prospects is the seashore mallow Kosteletzkya pentacarpos , an oilseed halophyte that grows on saline marginal lands [ 96 ], the seeds of which contain 18%–22% oil, which is comparable to cottonseed oil, which is edible, and shows some potential for biodiesel production [ 97 ]. Kosteletzkya pentacarpos can yield up to 1500 kg/ha of seeds, or up to 330 kg/ha of oil [ 86 ]. In addition, the Jerusalem artichoke ( Helianthus tuberosus , or topinambour) is widespread in the coastal zones of China and is considered likewise one of the most promising sources of biomass energy.…”

Comparison of critical methods developed for fatty acid analysis: A review

“…Knothe et al. employed 1 H NMR to determine the existence of cyclic FAs in seashore mallow ( Kosteletzkya pentacarpos L. Ledeb). A novel NMR technology, namely, comprehensive multiphase‐NMR, was introduced in 2012 for plant analysis .…”

“…The proposed method can be applied in various fields that require the quantification of specific cyclic compounds in mixtures of pharmaceuticals. Knothe et al [84] employed 1 H NMR to determine the existence of cyclic FAs in seashore mallow (Kosteletzkya pentacarpos L. Ledeb). A novel NMR technology, namely, comprehensive multiphase-NMR, was introduced in 2012 for plant analysis [76].…”
