gamma-sitosterol and Wounds-and-Injuries

Ethnobotanical field surveys revealed that various parts of Cichorium intybus L. has been used for wound healing in Turkish folk medicine.. The present study aimed at verifying the efficiency of various traditional prescriptions prepared from the aerial parts and roots of C. intybus experimentally and to define the components responsible from the activity by bioassay-guided procedures.. Initially, wound healing activity of the aerial parts, leaves, and roots as well as ashes of either leaves or roots were investigated. Subsequently, roots of the plant were submitted to further detailed investigations. The wound healing activity of the methanolic extract, its subextracts, and fractions were evaluated by using in vivo linear incision and circular excision wound models in rats. The hydroxyproline content of the tissues treated with test ointments were also assessed for the activity evaluation. Moreover, in order to find out a possible involvement of antioxidant activity in wound healing, the test samples were also investigated by DPPH radical scavenging activity and total phenolic concentration were also determined. Additionally anti-inflammatory activity was assessed by using the method of Whittle, which is based on the inhibition of acetic acid-induced increase in capillary permeability. Through the bioassay guided fractionation one compound was isolated and its structure was elucidated by spectroscopic methods. For the determination of the activity mechanisms, the fractions were screened for hyaluronidase, collagenase and elastase enzyme inhibitory activities.. Methanolic extract of C. intybus roots was found to possess potent wound healing activity. Then this extract was subjected to successive solvent extraction with n-hexane, dichloromethane (DCM), ethyl acetate and n-butanol. Each solvent extracts were also applied on the same wound models. DCM subextract was found to be the most active one and through chromatographic techniques DCM subextract was fractionated into several fractions and compound 1 was isolated as the compound being responsible from the wound healing activity.. The experimental study revealed that C. intybus methanolic extract displays wound healing effect and β-sitosterol was determined as the active compound responsible from the activity.

In traditional Indian medicinal treatise there are several Ayurvedic formulations mentioned which have been claimed as potential wound healing agents like Madhu Ghrita and Jatyadi Taila. Jatyadi Taila (JT) is a medicated oil formulation (Taila) popularly used in the treatment of various topical wounds.. Though JT has its composition recorded in ancient Ayurvedic texts, there have been minimal attempts to standardize its use in the management of wound. The current work evaluates the wound healing efficacy of JT and also provides evidence of the dermal absorption kinetics of Karanjin from JT.. JT was subjected to preliminary phytochemical evaluation. Therapeutically active marker components β-sitosterol, lupeol and karanjin were detected and separated using HPTLC. As a part of safety evaluation, skin irritation potential of JT was evaluated on rabbit skin. Excision wound model in rats were used to evaluate the wound healing efficacy of JT. Histopathological and biochemical evaluations of excised skin tissues at wound sites were carried out. The HPTLC method developed was also validated to evaluate the pharmacokinetics of Karanjin from JT after topical application on pinna of rabbit.. Preliminary phytochemical evaluation of JT revealed presence of flavonoids, essential oils, tannins, glycosides, steroids and alkaloids while resins were found to be absent. HPTLC confirmed the presence of karanjin, lupeol and β-sitosterol in JT. JT was found to be non-irritant when applied to the skin of rabbits. Topical application of JT on excision wounds caused significantly faster reduction in wound area as compared to the application of modern topical formulation (Neosporin(®)) and untreated control wounds. Animals treated with JT showed significant increase in protein, hydroxyproline and hexosamine content in the granulation tissue when compared with the untreated controls. Wound healing potential of JT was found to be dose dependant. HPTLC method was successfully used to evaluate the pharmacokinetics of Karanjin after topical application of JT on rabbit pinna.. Current work demonstrates a modern approach towards standardization of the use of traditional topical formulation JT. The results justify the traditional claim of JT for its use in the management of wounds.
