The main component of rosin natural gum is abietic acid, which has an interesting chemical structure to be studied with the influence of gamma-ray and the antimicrobial activity on the properties of a cheap abundant solid state natural material of rosin. Rosin is exposed to a wide scale of gamma-ray ranges from 0 to 100 kGy. The changes in the properties are tracked by various techniques of FTIR, XRD, TGA, GPC, and SEM. The molecular weight of rosin changes from 370 g/mol to higher and the morphological properties were investigated. The irradiated rosin acid (IRA) at different irradiation doses exploited antimicrobial effect versus Gram-positive and Gram-negative as well. The inhibition zone enhanced from 15 to 33, 14 to 28, 14 to 20, and 9 to 14 mm for Gram-positive and Gram-negative, respectively. Moreover, bioactive behavior for irradiated rosin of 40 kGy recorded the highest antibacterial activity against both types of bacteria. The outcome data of antimicrobial activity are good and confirm that there is a significant effect of irradiation dose on the biocidal activity of rosin.

松香天然胶的主要成分是松香酸，其具有有趣的化学结构，有待研究伽马射线的影响以及抗菌活性对廉价丰富的松香固态天然材料性能的影响。松香暴露于 0 至 100 kGy 的广泛伽马射线范围内。通过 FTIR、XRD、TGA、GPC 和 SEM 等各种技术跟踪性能的变化。松香的分子量从 370 g/mol 变化到更高，并研究了其形态特性。不同辐照剂量下的辐照松香酸（IRA）对革兰氏阳性菌和革兰氏阴性菌也具有抗菌作用。革兰氏阳性菌和革兰氏阴性菌的抑菌圈分别从 15 毫米增加到 33 毫米、从 14 毫米增加到 28 毫米、从 14 毫米增加到 20 毫米、从 9 毫米增加到 14 毫米。此外，40 kGy 辐照松香的生物活性行为记录了对两种细菌的​​最高抗菌活性。抗菌活性的结果数据良好，证实辐照剂量对松香的杀菌活性有显着影响。
