From those who want to know and its a slow day!
By Tom Mizukami on Monday, February 2, 2004 - 12:32 pm:
quantity sufficient
It is in common useage, I don't have a USP handy, but it should be defined in there.

Tom is correct. I believe it comes from the Latin 'quantum sufficit'.

According to my Merck Index, it's Latin for either quantum sufficiat or quantum satis

I agree, classic Merck, I found it as well in my 25 yr old analytical chemistry text.
