Black cumin (Nigella sativa) volatile oil has been use in public treatments for a long time. Nigella sativa seeds have wide therapeutic effects and have been reported to have significant effects against many ailments such as skin diseases, jaundice, gastrointestinal problems, anorexia, conjunctivitis, dyspepsia, rheumatism, diabetes, hypertension, intrinsic hemorrhage, paralysis, amenorrhea, anorexia, asthma, cough, bronchitis, headache, fever, influenza and eczema. One of the most active constituent is thymoquinone and has different beneficial properties. Poly lactice acid (PLA) is natural biodegradable material. It is widely used medical applications. Due to their biodegradability, they are well suited for the preparation of disposable devices. One of the key properties of the PLA matrix is its ease of degradation by the enzymatic or hydrolytic pathway. It is very suitable material for drug carrier and delivery. In this study different percentages of black cumin volatile oil were added to PLA film matrices. It was found that thermal stability and crystalinity of the PLA film were affected by add to black cumin volatile oil. We concluded that black cumin volatile oil added PLA films can be use as natural and biodegredable material for medical applications. [ABSTRACT FROM AUTHOR] |
