Semmler and Feldstein have isolated a lactone from costus root oil, which they named costus lactone, having the following characters —... [Pg.284]

Costic acid, C15H2.2O2, is a free acid isolated from costus root oil. It is an unsaturated bicyclic acid of specific gravity 1 0501. It forms a. methyl ester, boiling at 170° to 175° at 11 mm. [Pg.298]

Costus Root Oil occurs as a light yellow to brown, viscous liquid with a peculiar, persistent odor reminiscent of violet, orris, and vetivert. It is the volatile oil obtained by steam distillation from the dried, triturated roots of the herbaceous perennial plant Saussurea lappa Clarke (Fam. Compositae) or by a solvent extraction procedure followed by vacuum distillation of the resinoid extract. It is soluble in most fixed... [Pg.123]

IFRA and RIFM have forbidden the use of several essential oils and components, including costus root oil, dihydrocoumarin, musk ambrette, and balsam of Peru (Ford, 1991) a concentration limit is imposed on the use of isoeugenol, cold pressed lemon oil, bergamot oil, angelica root oil, cassia oU, cinnamic alcohol, hydroj citronellal, and oakmoss absolute. Cinnamic aldehyde, citral, and carvone oxide can only be used with a quenching agent. [Pg.638]

Cryptomeridiol (227) is a fully saturated eudesmane from heartwood of Cryptomeria japonica (381). From the heartwood of red sandal (Pterocarpus san-talinus) a number of eudesmanes have been isolated, of which pterocarpdiolone (228) may be mentioned (246). Costic acid (229), a eudesmane acid, is present in costus root oil (30). Laevojunenol (230) from vetiver oil (Vetiveriazizanioides) of North Indian origin is an example of e t-eudesmane derivative (345). Of the many presently known eudesmanolides only a few have been isolated from woody parts of plants (+)-dihydro-/8-cyclocostunolide (231) was obtained from trunkwood of Moquinea velutina (146).

Semmler and Feldstein have isolated a sesquiterpene alcohol, P, from the oil of costus root, to which they have given the name costol. It was purified by conversion into its acid phthalate, which, on hydrolysis yields the pure alcohol, having the following characters —... [Pg.156]

Confirmatory evidence has been provided for the revised structure of a guaiadiene (428) present in geranium oil/ Another component of costus oil has been identified as the triene acid (429) and an isomer (430) of guaioxide (cf. Vol. 1, p. Ill) has been isolated from the roots of a Ligularia species/ ... [Pg.102]

Stout tuberous roots of kuth are characterized by a penetrating aroma. Pale yellow or brownish viscous oil or costus oil is obtained from the roots either by steam distillation or through extracting with solvents. The oil contains resinoids (6%), essential oil (1.5%), Saussurine and other alkaloids (0.05%). Biological actions of costus oil are hyposensitive, bronchiodialatoiy, and antiseptic against streptococcus and streptophylococcus (Anonymous, 1976). [Pg.55]
