Let's assume you're talking about cut flowers. The commercially available OTC preservative powders work great, but you can save money and make your own with;
3 parts water (tap or spring, distilled is best), (i.e.36oz)
1 part citrus soda pop (7-up, Mountain Dew, Squirt, Wink, Ginger Ale, NOT DIET)
(i.e. 12 oz can) +
1 Tablespoon bleach.
These provide the necessary ingredients to sustain a plant for a couple of weeks. The water is obvious, the soda pop for food (sugar), and the citric acid found in these sodas provides and antibacterial along with the bleach.
If you are cutting Daffodils, make sure you change the water every 20 minutes for the first hour and DO NOT put other plants or flowers in with them as their sap is toxic to themselves and other plants. They expell "bad stuff" through their Phloem just as we expell CO2 through our lungs.
A great book to get is "Garden to Vase".

Vinegar would be the best preservative. You can also use a little bit of salt or even lemon as preservative. Sugar syrup can also be used as a preservative if you want your sauce to be sweet.

It is difficult to say "the best"; but salt is a good preservative.
The answer depends in part on your application. Also, 'best' in what sense? Formaldehyde is a very effective preservative for biological specimens, but is not suitable as a food preservative if you intend to eat the food, as it is quite toxic. Copper compounds are excellent wood preservatives, but are also quite toxic. If you are looking for a non toxic food preservative, try salt or vinegar!
