A volatile plant growth inhibitor from Spiraea thunbergii

Plant Growth Inhibitor from Abrus precatorius Seeds.

Tissue Culture and Production of Volatile Secondary Metabolites from Callus of Stevia rebaudiana at Different Combination of Plant Growth Regulators

 Stevia rebaudiana Bert (Asteraceae) is herbaceous plant with sweet leaves, which are the source of sweetener products. The present study focuses on effects of different combination of plant growth regulators on callus induction, callus cell growth and regeneration and volatile constituents from callus of stevia in tissue culture condition. The results of present study showed callus formation p...

Xerospiraea, A Generic Segregate of Spiraea (Rosaceae) from Mexico

The xeromorphic Mexican spiraeas (S. hartwegiana and S. northcrajii1) are shown by cladistic and phenetic analysis to be more closely allied to Petrophytum, Kelseya, and Luetkea than to the more mesophytic Spiraea. Within Spiraea the Mexican spiraeas appear more closely related to the Old World subgenus Metaspiraea. The xeromorphic Mexican spiraeas, as well as Petrophytum, Kelseya and Luetkea, ...

A new phenolic glycoside from Spiraea prunifolia var. simpliciflora twigs.

The phytochemical investigation of the methanol extract from the twigs of Spiraea prunifolia var. simpliciflora (Rosaceae) using column chromatography led to the isolation of a new phenol glycoside, 1-O-(E)-caffeoyl-2-O-p-(E)-coumaroyl-β-D-glucopyranose (1), together with 16 known phenolic compounds (2-17). The structure of this new compound was elucidated by analysis of spectroscopic data incl...
