Flower Colors and Their Anthocyanins in Saintpaulia Cultivars (Gesneriaceae)

  author={Fumi Tatsuzawa and Munetaka Hosokawa},
  journal={The Horticulture Journal},
The flower colors and anthocyanin constitution of sixteen cultivars of Saintpaulia were surveyed to determine the relationship between their flower colors and anthocyanin components. Six anthocyanins were isolated from the flowers of these cultivars as major anthocyanins along with three minor ones, and their structures were identified by co-HPLC or chemical and spectroscopic techniques. Among them, a novel anthocyanin, pelargonidin 3-O-[6-O-(4-O-(acetyl)-α-rhamnopyranosyl)-β-glucopyranoside…

Identification of Flavonoids in Leaves of a Labile Bicolor Flowering Dahlia (Dahlia variabilis) ‘Yuino’

The data demonstrated that flavonoid-rich leaves accumulated the flavonoids of butein and flavonol derivatives, and the importance of chalcone synthase for phenotypic lability in ‘Yuino’ was confirmed.

African violet (Saintpaulia ionantha H. Wendl.): classical breeding and progress in the application of biotechnological techniques

This review offers a short synthesis of the advances made in African violet breeding, including studies on mutation and somaclonal variation caused by physical and chemical factors, as well as transgenic strategies using Agrobacterium-mediated transformation and particle bombardment.

Histogen Layers Contributing to Adventitious Bud Formation Are Determined by their Cell Division Activities

Periclinal chimeral cultivar capable of propagation with adventitious shoots of Saintpaulia can be divided into two types, and the possibility was shown that cells in the L2 layer could form shoots by involving cells of the L1 layer with a low division activity.

Functional characterization of UDP‐rhamnose‐dependent rhamnosyltransferase involved in anthocyanin modification, a key enzyme determining blue coloration in Lobelia erinus

The results suggest that rhamnosylation is an essential process for lobelinin synthesis, and thus the expression of RT has a great impact on the flower color and is necessary for the blue color of Lobelia flowers.



Floral Pigments from the Blue Flowers of Nemophila menziesii ‘Insignis Blue’ and the Purple Flower of Its Variants

Two anthocyanins (pigments 1 and 2) were detected from the blue flowers of Nemophila menziesii ‘Insignis blue’ and the purple flowers of its variants as the main floral anthocyanins. These two

Acetylated Anthocyanidin 3-O-di-glycosides in Red-purple Flowers and Grayed-purple Leaves of Saintpaulia ‘Tomoko’

A new acetylated anthocyanin was extracted from the red-purple flowers of Saintpaulia ‘Tomoko’ with 5% HOAc-H2O or 5% formic acid-H2O, and determined to be peonidin

Flavonoids and their glycosides, including anthocyanins.

This review describes more than 600 new examples of naturally occurring flavonoids found either as aglycones or glycosides, comprising flavones, flavonols, chalcones, dihydrochalcones, aurones,
