Blackthorn (Prunus spinosa L.), a member of the Rosaceae family, is a plant species that typically grows in shrub form. It is commonly found in Europe, Western Asia, North Africa, and Anatolia. Known by various names such as sloe or wild plum, it holds significant value both in natural landscapes and agricultural production.

Biological and Ecological Features

Prunus spinosa is a thorny shrub ranging from 1 to 4 meters in height. It blooms with white flowers in spring, and its fruits, which typically mature in autumn, are usually purple. In Turkey, it naturally grows in regions such as Adana, Çanakkale, Tekirdağ, Balıkesir, and Edirne.

This plant species is known for its resistance to low temperatures and ability to thrive in poor soils. Its adaptation to arid conditions makes it a preferred choice in landscape architecture applications, such as erosion control and ecological restoration.

Usage Areas

Blackthorn (Prunus spinosa) is a versatile plant used for both functional and aesthetic purposes, with a wide range of applications from traditional medicine to the food industry.

Food and Beverage Industry

Its fruits are used in the production of marmalade, jam, juice, and liqueur.
The fruit pulp contains high levels of organic acids, flavonoids, and anthocyanins, enhancing its antioxidant capacity and making it beneficial for health.

Medicinal Use

Blackthorn fruits exhibit anti-inflammatory, antioxidant, and antiseptic properties. In traditional medicine, they are known for their hemostatic, metabolism-boosting, and immune-strengthening effects.
Experimental studies have demonstrated the positive effects of its methanol extract on wound healing.

Landscape Architecture

Due to its resistance to low temperatures and arid conditions, it is widely used in applications such as erosion control, windbreak creation, and biological rehabilitation.
Its aesthetic white flowers and fruits also make it a valuable ornamental plant.

Chemical Composition and Nutritional Values

Blackthorn is rich in phenolic compounds, flavonoids, anthocyanins, and vitamin C. Research has shown that its fruit peel and pulp contain high levels of antioxidants, which help neutralize free radicals and contribute to the prevention of chronic diseases such as cardiovascular conditions and cancer.

Pomological Features

A study conducted in Çanakkale revealed that blackthorn fruits have an average weight of 2.33 g, a pH value of 3.54, and a soluble solid content of 27.89%. These characteristics indicate that the fruit is both nutritionally and commercially valuable.

Prunus spinosa is a highly versatile plant with extensive potential for use in nature and agriculture. Promoting its proliferation in natural flora and cultivating superior genotypes is important for both ecological balance and economic benefits. Furthermore, more research into the biochemical properties of this plant is needed to expand its use in the medical and food industries.
