“…Research on the odour and flavour of onions and other edible plant species has shown that higher plants are capable of producing a wide variety of volatile sulphur compounds, including mercaptans, sulphoxides, and alkyl mono-, di-, and trisulphides (Ballance 1961;Carson and Wong 1961;Gumbmann and Burr 1964;Oaks, Hartman, and Dimick 1964). Since selenium is known to substitute for sulphur in a number of biological processes, it was reasoned that the characteristic odour of seleniferous vegetation might result from the substitution of selenium for sulphur in one or more of these volatile sulphur compounds.…”

“…Allyl sulphide, diallyl disulphide and dimethyl disulphide eluted in the first fraction, indicating that peak A was due to the fairly non-polar sulphides and disulphides reported to occur in garlic oil (Oaks et al 1964). Other reported components of garlic oil, ally1 cysteine-S-oxide (alliin) and diallyl disulphide oxide (allicin) (Stoll & Seebeck 1949) are more polar and would presumably be eluted later.…”

The effect of garlic extracts on contractions of rat gastric fundus and human platelet aggregation

Garlic has been extracted and separated chromatographically into various fractions which show different degrees of activity as inhibitors of platelet aggregation and smooth muscle. The most potent smooth muscle inhibitor fraction had little activity on platelet aggregation, but microgram ml-1 concentrations greatly reduced the contractions of rat gastric fundus to prostaglandin E2 and acetylcholine. Material in this fraction may contribute to some of the claimed therapeutic effects of garlic involving smooth muscle. Its identity is not known, but is different from allyl sulphide, dimethyl sulphide and diallyl disulphide. These compounds eluted earlier on liquid chromatography than the most active fraction, and they showed only modest inhibitory activity against prostaglandin E2 and acetylcholine on rat fundus.

The volatile constituents from the leaves and flowers of Adenocalymma alliaceum and the inflorescences of Petiveria alliacea were analysed by capillary GC-MS. The major components identified from A. alliaceum were diallyl disulphide (leaves: 34.0%; flowers: 49.7%) and diallyl trisulphide (leaves: 58.2%; flowers: 32.7%). The main compounds found in the inflorescences of P. alliacea were benzaldehyde (54.8%), benzyl thiol (20.3%) and dibenzyl disulphide (18.0%). These types of sulphur containing compounds are very common in both species of garlic and onion.
