Haloxylon salicornicum

Seven alkaloids have been isolated from Haloxylon salicornicum (named 1-7) and four of them have been shown to have a naph-thyridine skeleton. Alkaloid 1(159) can be considered as a derivative of either 1,8- or 1,6-naphthyridine, whereas alkaloids 2, 3, and 5, which structurally resemble 159, are possibly biogenetically related.241... [Pg.175]

The alkaloid (93) which is produced by Haloxylon salicornicum shows a structural resemblance to pelletierine (89). A feeding experiment58 with [6-14C]-lysine in intact plants has supported the related biosynthesis in Scheme 18. Activity was incorporated at C(6) of the alkaloid as shown. Surprisingly, no activity was incorporated from [2-14C]acetate but this negative result could be due to the failure of acetate to reach the site of synthesis. [Pg.23]
