Chemotaxonomy, Morphology and Chemo Diversity of Scutellaria (Lamiaceae) Species in Zagros, Iran [PDF]

, 2019
This study concerns to evaluate the morphological and flavonoid variations, and chemotaxonomy among seven Scutellaria species. The limits of Scutellaria species were disturbed by different factors including hybridization and polymorphism.

Chemotaxonomy of \u3ci\u3eTheobroma\u3c/i\u3e and \u3ci\u3eHerrania\u3c/i\u3e (Malvaceae) and \u3ci\u3eIlex \u3c/i\u3e(Aquifoliaceae) species

, 2019
Biosynthesis of purine alkaloids has arisen by convergent evolution in several plant families across the angiosperm phylogeny. Global secondary metabolite variation in these derived taxa is not well understood within the context of their congeners and ...

Chemotaxonomy of the Rabdosia in Japan by Diterpenoids

YAKUGAKU ZASSHI, 1998
Many diterpenoids containing mostly ent-kaurenoids have been isolated from the Rabdosia (Labiatae). The relation of the diterpenoids with its species in Japan has been studied. The ratio of diterpene types and the values of oxidation state in each plant were calculated.
