Stevia serrata

An X-ray analysis of rastevione, the main constituent of the roots of Stevia serrata and S. rhombifolia, has revealed it to have structure (284).144 This definitive assignment calls into question the relative stereochemistry assigned to more than fifteen other longipinene and longipinane derivatives isolated from various plant sources (see Vol. 7, p. 75, Vol. 9, p. 110, Vol. 10, p. 34). The tiglate (285) has been isolated from Eupatoriadelphus purpureus.lib...

H-)-a-Longipinene (347) arising from cation 337 was first found in wood of Pinus sylvestris (414). Many related compounds have since been isolated from woody tissues of higher plants (47) - for example, rastevione (348) from roots of Stevia serrata and S. rhombifolia (329). Longiborneol (juniperol, 349) is widely distributed in the Pinus spp. but was first obtained from bark of Juniperus...
