| "Steam distilled essential oil from aerial parts of Ruta chalepensis growing in Turkey was analyzed by GC and GC/MS. Twenty four compounds were identified representing 93.4% of the oil with [[http://www.thegoodscentscompany.com/data/rw1021151.html|2-undecanone]] (66.49%) and 2-nonanone (16.24%) as major constituents." \\ | "Steam distilled essential oil from aerial parts of Ruta chalepensis growing in Turkey was analyzed by GC and GC/MS.

| The exceedingly powerful thiol 1-methoxyhexane-3-thiol (herbaceous, pungent, repulsive; found in Salvia sclarea) was suspected to be part of the volatiles of a Ruta species where it was subsequently identified together with its homologue, 1-methoxyheptane-3-thiol, 1-methoxy-4-methylpentane-3-thiol, and 4-methoxy-2-methylbutane-2-thiol. \\ | The exceedingly powerful thiol 1-methoxyhexane-3-thiol (herbaceous, pungent, repulsive; found in Salvia sclarea) was suspected to be part of the volatiles of a Ruta species where it was subsequently identified together with its homologue, 1-methoxyheptane-3-thiol, 1-methoxy-4-methylpentane-3-thiol, and 4-methoxy-2-methylbutane-2-thiol. \\ |

| A solvent extract of sulfurous-sweaty smelling Ruta chalepensis contained 21 related organic sulfur-containing compounds, from which 19 were confirmed by comparison of their analytical data with those of authentic reference samples. These compounds belong to a family of natural flavor molecules having a 1,3-positioned O,S moiety in common like 1-methoxyhexane-3-thiol (known from Salvia sclarea) and 4-methyl-3-sulfanylhexan-1-ol e.g. The natural isomers of 4-methyl-3-sulfanylhexan-1-ol consisted of a 65:35 mixture of the (3R,4S)-isomer (onion, garlic, perspiration) and the (3S,4S)-isomer (weaker, not much character). The unnatural isomer (3R,4R) was described as 'rhubarb, green, and very natural grapefruit' by a chirospecific GC-sniffing experiment. \\ | |
