In realt� il frutto pi� ricco di vitamina C sarebbe la prugna kakadu,
seguita dalla bacca camu-camu o cacari, mentre al terzo posto troviamo
l'assai pi� nota ciliegia acerola, che ne contiene 8 volte la guava:
http://www.ivannikolov.com/what-fruit-is-highest-in-vitamin-c/
Kakadu plum (...) � 2,907 mg per 100 g fruit
Camu camu berry (...) � about 2,000 mg per 100 g fruit
Acerola (west indian cherry), raw � 1,678 mg per 100 g fruit
http://en.wikipedia.org/wiki/Terminalia_ferdinandiana
Its vitamin C concentration may be as high as 1000�5300 mg/100g
(compared with 50 mg/100g for oranges), possibly the highest known
of any fruit.
http://en.wikipedia.org/wiki/Myrciaria_dubia
The extraordinarily high vitamin C content (on the order of 2�3%
of fresh weight) is the most important property of the fruit, which
has been exploited in positioning camu camu on international markets.
http://en.wikipedia.org/wiki/Malpighia_emarginata
It is known for being extremely rich in vitamin C,
almost as much as camu camu, (...)
The fruit is edible and widely consumed in the species'
native area, and is cultivated elsewhere for its high vitamin C
content. There are 1677.6 mg of vitamin C in 100 g of fruit.
Notare che questi tre frutti hanno un contenuto cos� alto di vit. C
che, se venissero importati via aerea al giusto grado di maturazione,
potrebbero sostituire benissimo Cebion e Redoxon.
Specialmente per uso veterinario (cavie e cincill�), al quarto posto
ci sarebbe il frutto (cinorrodo) della rosa canina:
http://en.wikipedia.org/wiki/Rose_hip
Rose hips have recently become popular as a healthy treat for
pet chinchillas and guinea pigs. These small rodents are unable
to manufacture their own vitamin C and are unable to digest many
vitamin-C rich foods. Rose hips provide a sugarless, safe way
to increase their vitamin C intake. (...)
Rose hips are particularly high in vitamin C content, one of the
richest plant sources available. However, RP-HPLC assays of fresh
rose hips and several commercially available products revealed
a wide range of L-ascorbic acid content, ranging from 0.03 to
1.3%. Rose hips of some species, especially Rosa canina (Dog Rose)
and R. majalis, have been used as a source of vitamin C.

Con i cinorrodi della Rosa canina, molto ricchi di vitamina C,
si prepara una confettura ed in Slovenia viene prodotta una bibita
analcolica, la Cockta.
