A prune is a dried plum, most commonly from the European plum (Prunus domestica) tree. Not all plum species or varieties can be dried into prunes.{{cite book|title=Growing Prunes (Dried Plums) in California: An Overview|url=https://books.google.com/books?id=GxxjwNoAHgcC |year=2007 |publisher=UCANR Publications|isbn=978-1-60107-486-7}} Use of the term prune for fresh plums is obsolete except when applied to varieties of plum grown for drying.{{cite web|url=https://www.ams.usda.gov/grades-standards/dehydrated-prunes-grades-and-standards|title=Dehydrated Prunes Grades and Standards |publisher=Agricultural Marketing Service, US Department of Agriculture|date=2017|access-date=15 May 2017}} In this usage, a prune is the firm-fleshed plum fruit of P. domestica varieties that have a high soluble solids content, and do not ferment during drying.{{cite book |author=Richard P. Buchner |url=https://books.google.com/books?id=ZIOk7KIgDVAC&pg=PA75 |title=Prune Production Manual |date=16 May 2012 |publisher=UCANR Publications |isbn=978-1-60107-702-8 |pages=75–}}
Most prunes are freestone cultivars (i.e., the pit is easy to remove), whereas most plums grown for fresh consumption are clingstone (the pit is more difficult to remove). The sorbitol content of dietary fiber likely provides the laxative effect associated with consuming prunes. Prunes are 64% carbohydrates, including dietary fiber, 2% protein, a rich source of vitamin K, and a moderate source of B vitamins and dietary minerals.
Production
More than 1,000 plum cultivars are grown for drying. The main cultivar grown in the United States is the 'Improved French' prune. Other varieties include 'Sutter', 'Tulare Giant', 'Moyer', 'Imperial', 'Italian', and greengages. Fresh prunes reach the market earlier than fresh plums and are usually smaller in size. The great majority of commercially grown prune varieties are self-fertile and do not need separate pollinator trees.{{cite book|title=Growing Prunes (Dried Plums) in California: An Overview|url=https://books.google.com/books?id=GxxjwNoAHgcC&pg=PP2|year=2007|publisher=UCANR Publications|isbn=978-1-60107-486-7|pages=2–}}
=Name change=
In 2001, plum growers in the United States were authorized by the Food and Drug Administration to call prunes "dried plums".{{Cite web|url=https://abcnews.go.com/Health/story?id=117656&page=1|title=FDA Approves Prune Name Change|date=2006-01-06|publisher=ABC News|access-date=2016-07-14}} Due to a perception that prunes relieve constipation (perceived as derogatory), some distributors stopped using the word "prune" on packaging labels in favor of "dried plums".Janick, Jules and Robert E. Paull (2008). The Encyclopedia of Fruit and Nuts. CABI. {{ISBN|0-85199-638-8}}. p. 696.
Health effects
Prunes contain dietary fiber (about 7% of weight) which may provide laxative effects. Their sorbitol content may also be responsible for this, a conclusion reached in a 2012 review by the European Food Safety Authority. The report also demonstrated that prunes effectively contribute to the maintenance of normal bowel function in the general population if consumed in quantities of at least {{convert|100|g|oz}} per day.{{cite journal |title=Scientific Opinion on the substantiation of health claims related to dried plums of 'prune' cultivars (Prunus domestica L.) and maintenance of normal bowel function (ID 1164, further assessment) pursuant to Article 13(1) of Regulation (EC) No 1924/2006 |doi=10.2903/j.efsa.2012.2712 |journal=EFSA Journal |volume=10 |issue=6 |page=2712 |author=EFSA Panel on Dietetic Products, Nutrition and Allergies (NDA) |year = 2012|doi-access=free }}
=Nutrition=
Prunes are 31% water, 64% carbohydrates, including 7% dietary fiber, 2% protein, and less than 1% fat (table). In a reference amount of {{cvt|100|g}}, prunes supply 240 calories, and are a rich source of vitamin K (57% of the Daily Value, DV), copper (31% DV), and potassium (24% DV), with several B vitamins (12-14% DV) and other dietary minerals in moderate content (10–13% DV) (table).
=Phytochemicals=
Prunes and prune juice contain phytochemicals, including phenolic compounds (mainly as neochlorogenic acids and chlorogenic acids) and sorbitol.{{cite journal | pmid = 11401245 | year = 2001 | last1 = Stacewicz-Sapuntzakis | first1 = M | last2 = Bowen | first2 = PE | last3 = Hussain | first3 = EA | last4 = Damayanti-Wood | first4 = BI | last5 = Farnsworth | first5 = NR | title = Chemical composition and potential health effects of prunes: a functional food? | volume = 41 | issue = 4 | pages = 251–86 | doi = 10.1080/20014091091814 | journal = Critical Reviews in Food Science and Nutrition| s2cid = 31159565 }}

Prunes are used in preparing both sweet and savory dishes.
Contrary to the name, boiled plums or prunes are not used to make sugar plums, which instead may be nuts, seeds, or spices coated with hard sugar, also called comfits.{{cite magazine|url=https://www.theatlantic.com/health/archive/2010/12/sugar-plums-theyre-not-what-you-think-they-are/68385/|author=Kawash, Samira|date=22 December 2010|title=Sugar Plums: They're Not What You Think They Are|magazine=The Atlantic|access-date=13 July 2017}}
