Cover Story: Plant materials have gained considerable attention for their therapeutic properties, finding extensive use in pharmaceutical and cosmetic industries. In terms of chemical preservation, natural products are prone to changes due to degradation processes like oxidation, hydrolysis, isomerization, cyclization, or dehydration, which can occur enzymatically or chemically. Their short- or long-term stability can be influenced by various factors, including their physicochemical properties and environmental conditions such as packaging, temperature, humidity, light exposure, and oxygen availability. Given the significant variations in storage conditions, it is mandatory to establish concrete instructions. Therefore, conducting stability studies is essential to uphold the quality and longevity of natural materials, ensuring their optimal utilization. View this paper
