Langley first studied the action of drugs on the autonomic ganglia with the alkaloid nictoine obtained from Nicotiana tabacum. Subsequently, some other alkaloids were also foimd to possess similar effects, namely coniine from the poison Hemlock obtained from Conicum maculatum, gelsemine from the yellow jasmine and lobeline from the lobelia, a native of America. 

Common/vernacular names Yellow jasmine, wild jessamine, woodbine, Carolina yellow jessamine, and evening trumpet flower. 

Historically it was a total stereospecific synthesis (p. 25) of 3-epja//oyohimbane in 1954 that put all the conclusions up to that time on a solid basis. It also confirmed the opinion that the platinum catalysed hydrogenation of sempervirine was an all cis addition. Sempervirine (a constituent of yellow jasmine, Gel-semium sempervirens) had previously been synthesized thus. 

Source Indole was detected in jasmine flowers Jasminum officinale), licorice [Glycyrrhiza glabra), kohlrabi stems [Brassica oleraceavAT. gongylodes), and hyacinth flowers Hyacinthus orientalid at concentrations of 42 to 95, 2, 1.33, and 0.24 to 3.45 ppm, respectively. Indole also occurs in tea leaves, black locust flowers, corn leaves, petitgrain, and yellow elder (Duke, 1992). 

C13H20O3, Mr 224.30, is a volatile component of jasmin flower absolute. It is a colorless to pale yellow liquid, Z>po.25kPa 116-118°C, 1.022-1.028, 1.473-... 

Properties Clear, yellow, oily liquid jasmine-like odor. D 0.962-0.968, refr index 1.554—1.559. Aldehyde content 97%. Soluble in 6 volumes of 80% alcohol. Combustible. 

ChHi60, Mr 164.25, bpi kPa 78-79 °C, tfi° 0.9423, n 1.4989 occurs in jasmine absolute and contributes to its typical jasmine odor. It is a pale yellow, viscous liquid with a strong jasmine odor. Various stereospecific syntheses for c/s-jasmone have been reported. A patented method involves alkylation of 3-methyl-2-cyclopen-ten-l-one with cz. y-2-pentenyl chloride in an alkaline medium in the presence of a phase-transfer catalyst (e.g., tricaprylmethylammonium chloride) [121] ... 

C12H22O3, Mr 214.30, 0.i3kPa 102-103 °C, dg 0.974 -0.978, ng 1.448-1.451, is a colorless to pale yellow liquid with a sweet-floral, fruity, slightly woody, jasmine-like odor. It is prepared by a Prins reaction of 1-octene with formaldehyde and acetic acid and is used in perfumes for various flower types, especially jasmine. FCT 1992 (30) p. 5 S. 

C oH 02, Mr 168.24. A liquid with a fruity-flowery odor, bp. 95-96°C (40Pa). (-)-d-J. ([aJu -30.4°, neat), found, among others, in jasmin(e) absolute and tea flavor, (+)-d-J. occurs in tuberose absolute, peach and mango flavor. For general and stereoselective syntheses, see Lit.. The peach-like smelling y-J. in the (+)-form contributes to the flavors of peach, mango, and yellow passion fruit. For analysis and preparative chromatographic separation of the enantiomers, see Lit., biosynthesis Lit.. The jasmolac-tones A-D are bicyclic structures. ...

Bp. 134-135 °C (1.6 kPa), LD50 (rat p. o.) 5 g/kg, soluble in alcohol and other organic solvents, practically insoluble in water. Occurrence With ca. 3% content in jasmin(e) absolute J. is one of the decisive compounds for jasmin(e) odor and is also contained, among others, in orange flower absolute, peppermint oils, and tea flavor.

Isol. from many plants, e.g. twigs of white jasmine, seeds of yellow lupin (Lupinus luteus), lentils and ash manna (Fraxinus ornus). Cryst. + 4 or 5H2O. 

Occurrence. The tetrasaccharide has been isolated from about forty different plant species, and is usually found associated with sucrose and raffinose. It has been reported in the roots of Stachys species, in the twigs of white jasmine, in the seeds of yellow lupine Lupinus lutens), in soybeans Soja hispida), in lentils (Ervum lens) and in ash manna Fraxinm omm). 

Two species are found in Madeira. Jasmmum odoratissvmum bears yellow flowers, which retain when dry the natural perfume suggestive of a mixture of jasmine, jonquil, and orange blossom.
