Abstract

The anthocyanins of 130 cultivars, 13 lines and 3 wild forms of Iris ensata
were analyzed by HPLC, and these plants were classified into 16 types of
major anthocyanins. Among these types, 8 types such as petunidin 3RGac5G -
delphinidin 3RGac5G, delphinidin 3RGac5G - petunidin 3RGac5G, cyanidin
3RGac5G - peonidin 3RGac5G, delphinidin 3RG - delphinidin 3RGac, petunidin
3RG5G - malvidin 3RG5G, malvidin 3RG5G - peonidin 3RG5G, peonidin 3RG5G -
cyanidin 3RG5G and peonidin 3RG - cyanidin 3RG were obtained as new types.
In these new types, peonidin 3RG - cyanidin 3RG and peonidin 3RG5G -
cyanidin 3RG5G types were noteworthy because cyanidin 3RG and cyanidin 3RG5G
are useful for the breeding of red flowers in I. ensata.

bearded iris by far the most common anthocyanin pigment is delphinidin in
its many forms with sugars and hydroxyls connected at two different
atatchement points and the chemicals attatched to these attatchments. Of the
other pigments the only other one to be found is Malvidin and it had only
been found in the cultivar of Frank Adams, and not identified as being in
any other cultivars. Malvidin is found in fushias and many other flowers,
but always in conjunction with delphinidin. The pigment floridor had also
been found in the diploid Florador and a couple of seedlings but so far has
never been identified in any tetraploids. (WOI pg 360-364)

have many shadings but all violet/purple, not too wide a range. A lot of
intensity diferences though.

via kitchen chemistry, more common then previously thougt. These are cream
and light yellow and can really change the tone and the appearance of the
cartenoid and the light shades of anthocyanins.
