β¦ 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.

In the previous paper (l), we reported the structure of Nervosine which was isolated from Liparis nervosa Lindl.. We further studied two plants, Liparis Kurameri French. et. Sav." and Liparis Kumokiri F. Maekawa\*\*, both of which are Liparis species of the Orchidaceae
The Bmzilian tree Aspidosperma dasycarpon 3 A. DC. has already yielded a number of interesting congeners4 (II-VI) of I u eine (I$ as well as the novel alkaloid apparicine (Vll).6 We should now like to record the isolation of still another alkaloid, "aspidodasycarpine, " to which we attribute structu
