Maali resin

Schimmel Co. have isolated a sesquiterpene alcohol from Samoan resin, known as Maali resin, and by dehydrating it by means of formic acid have obtained a sesquiterpene which has not been named other than as Maali sesquiterpene. It has the following characters —... 

Among the tricyclic aromadendrols viridiflorol (202), which occurs, for instance, in peppermint oil from Piedmont Mentha piperita L. Italo-Mitcham), is supposed to confer to this essential oil its characteristic note. When added to normal peppermint oils, (202) enhances their sweetish scent without modifying their taste and aroma 415). A dia-stereoisomer of (202), globulol, is present in eucalyptus oil, and is described as odorless 204). Maaliol (203), an alcohol which was first isolated from maali resin 62), was found in fresh roots of Valeriana officinalis L. (595) and also in the Indian variety Valeriana Wallichii D.C. 416). Maaliol-containing oils from Valeriana Wallichii D.C. are said to have a finer odor 582). In addition, maalioxide (204) 62) was found in the same oil 416 presumably as an artifact of alcohol (203). The cyclic ether is characterized by its fine woody odor quality 443). 

Markownikoff cyclization of 353 is represented by maaliol (360), a component of Maali resin, a soft exudate from Canarium samonense (275 vol. Illb). A related compound is maalioxide (361) from roots of Valeriana wallichii (305). Rearrangement of maaliane cation 355 (cf. Fig. 8.1.11), as shown in Fig.8.1.16, leads to the carbon skeleton of aristolene (362), which occurs in the essential oil from roots of Nardostachys jatamansi. (-i-)-Aristolene (a-ferulene) is present in the latex of Ferula communis (312). From roots of Aristolochia debilis, hydroxyketone 363 has been isolated (241).
