antipodes. (-Santolinenone too is inactive and probably racemic. Its hydroRylenaiae 
derivative melts at 62°. The third ketone is laevo-rotatory and yields a dextrorotatory 
oxime of the m. p. 116 to 117°. The ketone can only be regenerated with difficulty 
by means of acids. 
Thujone, which had been suspected by us in santolina oil*), could not be ascertained. 
Sho-Gyt and Yu-Ju Oils. A tree occurs in many parts of Formosa which, 
as reported by K. Nagai’), shows a great similarity to the camphor tree, but differs 
from it from a botanical point of view as well as in the composition of the oil. The 
natives call it “Gu-Chiu”. About the botanical position nothing is known. All that 
is known is that the tree probably belongs to the N.O. of Lawraceae. The “black 
camphor tree’ seems to be identical with this tree, but as long as no flowers have 
been collected and examined, it will hardly be possible to ascertain the botanical 
name. The leaves of the Sh6-Gyu tree are much thicker and of a darker green colour 
than the camphor leaves. As the leafy branches are frequently so high up that it is 
difficult to reach them, the easiest way to distinguish the trees is by scraping a little 
bit of the wood, preferably from the roots; by the odour it is then recognized whether 
we are in the presence of a camphor or a Shé-Gyu tree. The wood gives a yield of 
1,3 to 3 p.c. of oil (the average being 2,5 p.c.). A total yearly production of 600000 kin 
would be easily possible. The oil has the following properties: d0,900 to 1,031; 
a) +7,75 to + 30°; np 1,4750 to 1,51302; acid v. 0,1 to 0,96; ester v. 0 to 2,40; ester v. 
after acetylation 46,6 to 129,4; soluble in 1 to 12,5 volumes of 80 p.c. alcohol. Quite 
a number of component parts were ascertained, as specified in the following 
paragraphs. 
Formaldehyde, characterized by Rimini’s®) reaction. 
Sabinene. This hydrocarbon was contained in a fraction of the b.p. 163 to 167° 
and was recognized by oxidation to sabinenic acid (m. p. 57°), and by its conversion 
to sabina ketone. «-pinene and camphene could not be proved, at least neither a 
nitrosochloride nor solid zsoborneol were obtained. 
Dipentene. From a fraction of the b. p. 174 to 178° Nagai obtained dinate 
tetrabromide, m. p. 123 to 124°. 
a- as well as y-terpinene occur in Sh6-Gyt oil and were characterized by oxidation 
to the erythritol (y-terpinene) m. p. 236° and to 7-a,a’-dihydroxy-«-methyl-«’-isopropyl- 
adipic acid (a-terpinene), of the m. p. 188 to 189°. 
Linalool. It was impossible to ascertain the presence of this body beyond doubt. 
The fraction of the b. p. 207 to 213° contained terpinenol-4, the presence of which 
was established by conversion to terpinene terpin and 1,2,4-trihydroxyterpane. After 
oxidation with alkaline permanganate of potassium solution «@, «’-dihydroxy-a-methyl- 
a'-iso-propyladipic acid was formed from the trihydroxyterpane, which in its turn was 
converted in acid solution and by means of permanganate of potassium into #-dimethyl- 
acetonylacetone. On boiling with dilute hydrochloric acid trihydroxyterpane formed, 
besides p-cymene and carvenone. Further, the nitrosochloride melted at 111 to 112°, 
the nitrolpiperidine at 172 to 174°, phenylurethane at 71 to 72°, and naphthylurethane 
at 105,5 to 106,5°. Terpinenol is present in the oil in fairly large quantities.
