regex extract digit + word [duplicate]

I want to extract the exact value+unit from the 8 rows below. But my code is not working properly. For example, my code extracts in row 4 "1000 2 ounce" instead of only "2 ounce". Same issue with row 5 and 6.

  1. includes chalkboard labels, marker & measuring cup capacity s | 135.2 ounce capacity
  2. 33% thicker - 12 glass spice - 3 cubic inch capacity
  3. nolopau 1.53 gallon capacity lon glass jar,
  4. [1000 2 ounce capacity compostable condiment souffluide bagasse
  5. bia cordon bleu inc 900712 8.5 ounce capacity porcelain
  6. bekith 15 9 liter capacity glass jars,
  7. echtpower bento box, 1.5 milliliter lunch box with handle
  8. aislor plastic straining 0.50 gallon capacity lon pitcher, dishwasher

Outcome for each row: 153.2 ounce 3 cubic inch 1.53 gallon 2 ounce 8.5 ounce 9 liter 1.5 milliliter 0.50 gallon

I tried:

def extract_c(df):

pattern =  (\d+.\d+\s*ounce|\d+.\d+\s*cubic\s*inch|\d+.\d+\s*gallon|\d+.\d+\s*liter|\d+.\d+\s*milliliter)'

return df.str.extract(pattern)

Can anyone support me in extracting these 8 rows in 1 line?
