Does all the citrus fruit contain Citric acid and Ascorbic acid? While reading a sixth class book about acid bases and salts. I figured that that citrus fruits like lemon, orange etc.. contains **citric acid**. But in the same book they also given that amla contains **Ascorbic acid**. Amla being a citrus fruit should contain Citric acid. I am just confused with this. > Just tell me whether all the citrus fruits contains both citric acid as well as ascorbic acid. I checked in wikipedia & also in oxford dictionary.

Whatever the colloquial/vernacular/etymological meaning of "citrus"; when it comes about scientific names; _Citrus_ is a particular genus. It do have many species.

> "Amla being a citrus fruit"

No. Amla ( _Phyllanthus emblica_) is not a member of genus Citrus; not even allied.

Ascorbic acid is just another name for Vitamin C. It is also present in common edible citrus fruits.
