Antihemorrhoidal activity of organic acids ofCapsella bursa-pastorison croton oil-induced hemorrhoid in rats

Abstract

This study was aimed to investigate the antihemorrhoidal effects of ethanol (CBE) and water extracts (CBW) ofCapsella bursa-pastoris,an edible plant and a precipitant (CBW-1) obtained from the CBW in croton oil (CO)-induced hemorrhoid model in rats. CBW-1 was contain three organic acids, citric acid (36.09%), malic acid (35.56%), and quinic acid (17.73%). Hemorrhoids were evaluated by histopathology of recto-anal tissues and biochemical parameters in plasma and recto-anal tissues of rats. CBW, CBE, and CBW-1 significantly reduced hemorrhagic necrotic enteritis induced by CO. CO also increased the cytokines and lipid peroxidation (LPO) in serum, and myeloperoxidase (MPO) activity and LPO in recto-anal tissues, and reduced the GSH, CAT, GPx, and SOD levels in serum and recto-anal tissues. However, CBE, CBW, and CBW-1 ameliorated the levels of the cytokines, LPO, MPO, and the antioxidants. Our results conclude that the curative effect ofCapsella bursa-pastorisis closely related with its organic acids constituents, citric, malic, and quinic acids. Practical applications The fresh leaves ofCapsella bursa-pastorisare edible, eaten raw or cooked, and also used in salad. It has a widespread traditional usage in the treatment of the hemorrhoids in the Anatolia and in the Middle East Countries. According to our literature survey, any scientific evidence has not been found in the literature thatC. bursa-pastoriscould be used in the treatment of hemorrhoids. Therefore, in the current study, we aimed to investigate the antihemorrhoidal and antioxidant effects of ethanol and water extracts, and a precipitant (CBW-1) obtained from the CBW ofC. bursa-pastorisin croton oil (CO)-induced hemorrhoid model in rats. The current results showed that its water extract and CBW-1 containing three organic acids, citric acid (36.09%), malic acid (35.56%), and quinic acid (17.73%) significantly reduced the hemorrhagic necrotic enteritis induced by CO ameliorating the levels of the cytokines, LPO, MPO, and the antioxidants. Our results conclude that the curative effect ofC. bursa-pastorisis closely related with its organic acids constituents, citric, malic, and quinic acids.
