Phytochemical Characterization of Extracts From Aesculus hippocastanum L. Seeds and Quantification of Saponins Using HPLC-DAD and a Novel Tensiometric Approach. [PDF]

Chem Biodivers
Aesculus hippocastanum L. seed extracts prepared according to pharmacopeial methods were comprehensively characterized using HPLC‐DAD‐ESI‐MSn and GC‐MS. Furthermore, a novel bubble pressure tensiometric approach and an HPLC‐DAD method were employed for the quantitative analysis of surface‐active components.

Rapid degradation of auxin/indoleacetic acid proteins requires conserved amino acids of domain II and is proteasome dependent

, 2001
Auxin rapidly induces auxin/indoleacetic acid (Aux/IAA) transcription. The proteins encoded are short-lived nucleus-localized transcriptional regulators that share four conserved domains. In a transient assay measuring protein accumulation, an Aux/IAA 13–

COLORIMETRIC ESTIMATION OF INDOLEACETIC ACID [PDF]

Plant Physiology, 1951
The wide use of the auxin, indoleacetic acid, in physiological and biochemical experiments has promoted interest in methods for its colorimetrie estimation. Mitchell and Brunstetteb (1) have proposed both the nitrite and the ferric chloride-sulphuric acid tests for the quantitative estimation of indoleacetic acid (IAA) in aqueous solutions, basing ...

Comparison of Zeatin Indoleacetate with Zeatin and Indoleacetic Acid in the Tobacco Bioassay [PDF]

Plant Physiology, 1972
Zeatin indole-3-acetate, 6-[4-(indole-3-acetoxy)-3-methyl-trans-2-butenylamino]purine, is at least as effective as zeatin on a molar basis in satisfying the cytokinin requirement for growth and bud formation in tobacco bioassays. It is less effective than indole-3-acetic acid and is needed as a variable function of the cytokinin concentration for ...
