✦ Synopsis


On the basis of morphorogy, it is very difficult to classify some plants in the Liparis species of Orchidaceae. We have examined the possibility of chemotaxonomical classification in several plants of the Liparis species. From our observation, it is clear that some Liparis species of the Orchidaceae family contain new types of alkaloids which are similar to each other. In this communication, we wish to report the structure of Nervosine ( 1 ), named bv us, which was isolated from Liparis nervosa Lindl.*.

(1) Nervosine ( I ), ( C36H53012N'H20 -C6H307N3, m.p. 130 -13i, as picrate; C?)&+l2.8'as HCl salt ( methanol ); pKi: 10.0 ( 66 % methanol ); Rf: 0.62 ( n-BuOH : AcOH': H20 = 4 : 1 : 1 ); negative Tollens test ), shows strong bands at 3400 and 1120 -980 cm-l in its IR spectrum and a positive Benzidine -HI04 test which indicate that Nervosine ( I ) is a glycoside. * Japanese name is Kokuran.
