A NEW ALKALOID FROM THE SEEDS OF ALLIUM TUBEROSUM

从百合科植物韭 ( Allium tuberosum Rottler)的种子中分离并鉴定了 7个化合物 :1,2 ,3,4 - tetrahydro- 4 - hydroxy- 4 - quinolin carboxylic acid( ) (命名为韭子碱乙 ,Tuberosine B) ,7- hydroxy- 2 ,5- dimethyl 4 - H- 1- Benzopyran- 4 - one ( ) ,Vernolic acid( ) ,3- methoxy- 4 - hydroxybenzoic acid ( ) ,p- Hydroxybenzoic acid ( ) ,3,5-dimethoxy- 4 - hydroxybenzoic acid( ) ,Syringaresinol( )。其中 为新化合物 ,其它化合物均为首次从该植物中分得。

Seven compounds were isolated from the seeds of Allium tuberosum Rottler.On the basis of chemical and spectrospic analysis,they were identified as:1 ,2 ,3,4- tetrahydro- 4 - hydroxy- 4 - quinolin carboxylic acid( ) ( named Tuberosine B) ,7- hydroxy- 2 ,5 - dimethyl 4- H- 1 - Benzopyran- 4 - one( ) ,Vernolic acid( ) ,3- methoxy- 4 - hydroxybenzoic acid( ) ,p- Hydroxybenzoic acid( ) ,3,5 - dimethoxy- 4 - hydroxybenzoic acid( ) ,Syringaresinol( ) . was a new alkaloid. ～ were isolated from the seeds of Allium tuberosum for the first time.
