TL;DR: In this paper, the location and nature of cyanogenic compounds in kusum oil were determined using chromatographic and infrared spectroscopy methods, and it was shown that at least two glyceride molecules are involved.
Abstract: Chemical methods, chromatography and infrared spectroscopy have been applied to ascertain the location and nature of the cyanogenic compounds in kusum oil. Observations indicate the cyanogenic compounds to be a part of glyceride molecules in which one of the hydroxyl groups of the latter is bonded to the cyanogenic compound through an ether linkage. Chromatographic behavior of the isolated cyanogenic compounds further indicates that at least two glyceride molecules are involved. These glycerides are predominantly esterified with saturated fatty acids.

TL;DR: In this article, a non-edible oil bearing plant has been used as an ideal feedstock for biodiesel development in the present study and various physical and chemical parameters of the raw oil and the fatty acid methyl esters derived have been tested to confirm its suitability as a biodiesel fuel.

TL;DR: The present work has not only established the escalation obtained due to ultrasonication but also exemplified the two-step approach for synthesis of biodiesel from non-edible kusum oil based on the use of heterogeneous catalyst for the transesterification step.

TL;DR: The cyanogenic glycosides, here defined as glycosidic derivatives of α-hydroxynitriles, represent a rather limited class of natural products, which are widely distributed in the plant kingdom and, to a small extent, even in animals.
Abstract: The cyanogenic glycosides, here defined as glycosidic derivatives of α-hydroxynitriles, represent a rather limited class of natural products, which are widely distributed in the plant kingdom and, to a small extent, even in animals. A characteristic feature of these glycosides is their ability to release hydrocyanic acid on treatment with dilute acids or appropriate enzymes. The term “cyanogenic” is used to designate this property, regardless of whether pure substances, plants, or animals, are serving as the source. In the latter cases the term “cyanophoric” is occasionally employed synonymously.

TL;DR: A number of seed oils have been investigated with respect to their cyanolipid constituents as mentioned in this paper, which consist of long-chain fatty acids esterified with an unsaturated isoprenoid hydroxy- or dihydroxynitrile.
Abstract: A number of sapindaceous seed oils have been investigated with respect to their cyanolipid constituents. All but one of the oils have this new class of lipids in amounts ranging from 13% to 55%. These cyanolipids are of four different types, but all consist of long-chain fatty acids esterified with an unsaturated isoprenoid hydroxy- or dihydroxynitrile. The large amounts of C20 acids usually found in these oils indicate an appreciable cyanolipid content because such acids are preferentially incorporated in nitrile-containing fractions.Cardiospermum halicacabum L. seed oil was shown to contain 49% of a diester having two fatty acid moieties esterified with 1-cyano-2-hydroxymethylprop-2-ene-1-ol and 6% of another diester derived from 1-cyano-2-hydroxymethylprop-1-ene-3-ol. Treatment of the latter diester with methanolic hydrogen chloride produces methyl 4,4-dimethoxy-3-(methoxymethyl) butyrate from the dihydroxynitrile moiety.
