What is the definition of naturally occurring components?

Naturally occurring components are the chemical makeup which is naturally found in the herb.

For example:  If we were to talk about a fruit, let's say an orange.  
The naturally occurring components of the orange would be:
Vitamin C, essential oils, flavoniods, esters, etc.

If we look at an herb, say Yu Xing Cao.
