Page 88 - ... almost entirely of methyl salicylate, as was proved by the examination. A. Desmouliere, who appears to have had no knowledge of this previous examination, now makes the same observation, and finds, further, that methyl salicylate is not present as such in the pansy, but, as in the case of Betula lenta and other plants, occurs in the form of glucoside, which in the presence of water, under the influence of a ferment, is split up into methyl ester of salicylic acid and grape-sugar. He has succeeded...

Page 89 - Flacourt1) makes some interesting communications respecting the cultivation of ylang ylang trees in Reunion, which are based on practical experience, and therefore contain much useful instruction for those who are interested in the subject. Both Unona latifolia and Unona odorata which have now for a long time been grown as trees for avenues, are suitable for the cultivation. But an absolute necessity therefor are a tropical tranquil climate, and a porous soil containing a certain amount of moisture.

This is done by cutting off the tops, which at the same time causes a powerful development of the lateral branches and an abundant formation of blossoms, so that the yield becomes very remunerative. The flowering period of the...

The plants, transposed in one or other manner, require about two months to attain a height of 25 to 30 cm. and to develop sufficiently. At this stage the plants are best suited to the process of transferring to the plantations. During the next two years the latter must be tended with care, and yet yield nothing.
Page 89 - But an absolute necessity therefor are a tropical tranquil climate, and a porous soil containing a certain amount of moisture. In order to grow the trees from seed, the latter, taken from the ripe fleshy berries, must be freed carefully by repeated washing from all traces of pulp, and immediately after the last washing be placed in the seed-bed which may be laid out in a rich, well-manured soil.
Page 90 - ... to February, but a regular formation of blossoms giving the best yield can only be reckoned upon from May to August. Those blossoms which are freshest when submitted to distillation yield oils of better quality. 50 to 64 kilos of freshly gathered blossoms produce 1 kilo oil, ie 1,56 to 2 °/0.
Page 18 - The odour of the oil showed a great similarity to that of ordinary cananga oil, but left something to be desired with regard to delicacy. This drawback, though, may in future possibly be removed by a more rational method of production.
Page 88 - From the fact that the odour of wintergreen oil only occurs when the herb is rubbed, Desmouliere concludes that the glucoside and the ferment are contained in different cells of the plant, and solely for this reason were unable to act already previously on each other.
Page 65 - ... which is identical with the one obtained by Semmler. If to the myristicin or isomyristicin dissolved in glacial acetic acid, and cooled in ice, bromine is added up to the formation of a permanent yellow colour, there are formed in both cases disubstituted dibromides.
