Pine bark extract
Pine bark extract is a natural substance derived from pine bark, rich in oligomeric proanthocyanidins (OPCs). In 1947, French scientist Jacques Masquelier first isolated OPCs from peanut shells; pine bark has since emerged as a new source of these compounds. The OPCs in pine bark extract exhibit antioxidant activity that is 20 times stronger than vitamin C and 50 times stronger than vitamin E. This substance is non-toxic, non-carcinogenic, and highly safe. Its main components include proanthocyanidins, polyphenols, and other flavonoid compounds. It typically appears as a reddish-brown powder.

II. Product Introduction
1. Source
Pine bark extract—proanthocyanidins 95%—is a highly purified active ingredient derived and refined from the inner bark of trunk tissues of pine species belonging to the genus Pinus within the family Pinaceae, including Pinus massoniana, Pinus tabuliformis, and Pinus kesiya. It is extracted using modern biotechnology processes that maximize the preservation of the structural integrity and biological activity of proanthocyanidins.
2. Core Efficacy and Applications
(1) The pharmaceutical field
Proanthocyanidins extracted from pine bark exhibit potent antioxidant activity, with an antioxidant capacity 20 times that of vitamin C and 50 times that of vitamin E. They can effectively scavenge free radicals in the body and protect cells from oxidative damage. These compounds can be used as an adjunct to improve cardiovascular health, enhance vascular elasticity, reduce capillary permeability, and exert positive effects in alleviating chronic venous insufficiency and reducing edema. In addition, their anti-inflammatory and anti-allergic properties can help relieve inflammatory responses such as arthritis, while also possessing certain immunomodulatory functions that boost the body’s resistance.
(2) Food sector
As a natural antioxidant and colorant, pine bark extract can be used in foods such as fruit juices, fruit wines, dairy products, baked goods, and confectionery. As an antioxidant, it effectively slows down food oxidation and spoilage, thereby extending shelf life. As a colorant, it imparts a natural reddish-brown hue, enhancing the visual appeal of food products and aligning with the growing consumer trend toward natural and healthy foods.
(3) Cosmetics field
Thanks to its outstanding antioxidant capacity, pine bark extract—containing 95% procyanidins—can effectively neutralize free radicals in the skin, inhibit melanin production, reduce hyperpigmentation, and simultaneously promote collagen synthesis, enhancing skin elasticity and delaying skin aging. Its anti-inflammatory and soothing properties can help alleviate skin sensitivity and redness, making it suitable for formulating a wide range of cosmetic products, including anti-aging creams, whitening serums, and skincare products for sensitive skin.III.
