Upon distillation with water vapor of so-called East African sandal wood, which, as was ascertained by a botanical investigation, probably originated from a species of Osyris, presumably tenuifolia, Engl.3), Schimmel & Co.4) obtained 4,86 p.c. of a light brown oil. Its odor reminded one somewhat of that of vetiver oil and at the same time of that of gurjun balsam, but was quite distinct from that of sandal wood oil. d15o 0,9477; aD - 42° 50'; nD20o 1,52191; E.V. 11,1; E.V. after acetylation 72,8 which corresponds to 30,5 p.c. of a sesquiterpene alcohol C15H260 if such be present. The oil is rather difficultly soluble, since it requires 7 to 8 vol. of 90 p.c. alcohol to dissolve 1 vol. of the oil.
Two oils from African sandal wood, about the botanical origin of which nothing is reported, are described by H. Hasnsel5).

Judging by the similarity of properties, a like botanical origin with that of the osyris oil does not seem improbable: d20o0,9589 and 0,9630; aD - 40,6 and -60,96°; A.V. 1,7; S.V. 17,9"and 8,1; S.V. after acetylation 88,3 and 68,6. These oils contain a ses-quiterpene (b.p. 263,5 to 265° under 447 mm. pressure; d20o0,9243; aD -32,91°) and a sesquiterpene alcohol (b.p. 186 to 188° under 25 mm. pressure).
