| "The odorants could be divided into floral-rosy-citrusy notes: citronellol (9.6%), geraniol (8.4%), nerol (1.3%), citronellyl acetate (1.1%), geranyl acetate (3.3%), geranial + benzyl acetate (0.96%), neral (0.02%), benzyl alcohol (35%), phenethyl alcohol (0.78%), phenylacetonitrile (3.0%), farnesol (1.9%) and 2,3-dihydrofarnesol (0.88 %), green-grassy notes: (Z)-3-hexen-1-ol (11%), (Z)-3-hexenyl acetate (7.8%), (Z)-3-hexenal (trace) and (E)-2-hexenal (0.18%), green pea and galbanum-like notes: 2-isopropyl-3-methoxypyrazine (trace) and 2-isobutyl-3-methoxypyrazine (trace), fatty, waxy, aldehydic notes: octanal (0.15%), nonanal (0.1 %), decanal (0.07%) and fruity, raspberry notes: β-ionone (trace)." \\ | GC-MS analysis of vacuum headspace samples of the flower scent showed main components with floral-rosy-citrusy notes like citronellal, citronellol (9.6%), citronellyl acetate (1.1%), geranyl acetate (3.3%), nerol (1.3%), geraniol (8.4%), benzyl alcohol (35.2%), phenylethyl alcohol (0.78%), geranial + benzyl acetate (0.96%), neral (0.02%), phenylacetonitrile (3.0%), farnesol (1.9%) and 2,3-dihydrofarnesol (0.88 %); green-grassy notes like (Z)-3-hexen-1-ol (10.6%), (Z)-3-hexenyl acetate (7.8%), (E)-2-hexenal (0.18%), and (Z)-3-hexenal (trace); fatty, waxy, aldehydic notes like octanal (0.15%), nonanal (0.1 %), and decanal (0.07%). \\ |

| | „…studies performed at Firmenich also revealed trace amounts of phenylacetaldehyde oxime, which exhibits an interesting muguet-orange flower duality when in pure form. It was proposed that its combination with 2,3-laevo-dihydrofarnesol could reproduce the key note of the flower; however, the instability of this oxime prevents its use on industrial scale.“ \\ |

| | Main volatile constituents of a diethyl ether extract of C. majalis flowers from Serbia were benzyl alcohol, citronellol, geranyl acetate, 2,3-dihydrofarnesol, (E)-cinnamyl alcohol, and (E)- and (Z)-isomers of phenylacetaldehyde oxime. \\ |

| The standardised (effect correponding to 0.2% convallatoxin) powder of dried aboveground parts of C.majalis (Convallaria herba) is used against mild cardiac insuffiency. "Convallatoxin is similar to other cardiac glycosides. It inhibits Na+,K+ ATPase and indirectly increases intracellular Ca+ concentration.This strengthens the contraction of the heart muscle... The herb is very toxic and must only be administered under the supervision of a qualified practioner." \\ | The standardised (effect corresponding to 0.2% convallatoxin) powder of dried aboveground parts of C.majalis (Convallaria herba) has been used to treat mild cardiac insuffiency.
