Phthalic acid esters are widely used worldwide as plasticizers. The high consumption of phthalates in China makes it the world's largest plasticizer market. The lack of phthalic acid ester's chemical bonding with the polymer matrix facilitates their detachment from plastic products and subsequent release into the environment and causes serious threats to the health of living organisms.

These components give HPCE significant antibacterial and antioxidant properties, making it a valuable option for wound healing. Unlike traditional wound dressings that may leave a residue or necessitate invasive procedures like phototherapy, HPCE is a promising alternative.

- Plant callus, particularly from Hypericum perforatum, is rich in beneficial compounds like hyperforin and hypericin that have antibacterial and anti-inflammatory properties, making them useful for wound healing.
- A new wound dressing made from poly(vinyl alcohol), chitosan, and alginate is infused with Hypericum perforatum callus extract (HPCE) and has shown favorable properties such as high swelling capacity and mechanical strength, enhancing tissue regeneration.
- In laboratory and animal studies, this dressing has been proven to be biocompatible, promote healing processes like re-epithelialization and collagen deposition, and reduce the risk of fibrosis after wounds heal, while also combating antibiotic-resistant bacteria.
Article Synopsis
- Rice exhibits beneficial properties, including antioxidant and anti-inflammatory effects, making it a valuable plant for cosmetics and pharmaceuticals.
- The study focused on using rice callus extracts, developed with the 2,4-D hormone, to inhibit melanoma cell growth and enhance skin whitening.
- Results showed that rice callus extracts, particularly the aqueous version, are more effective than arbutin in reducing melanin production, suggesting their potential use in skin-lightening products.
Article Synopsis
- - Artemisia absinthium has been used for its antimicrobial and antioxidant properties, with notable secondary metabolites like gallic acid and p-coumaric acid found in the plant.
- - The study investigates how microcrystalline cellulose (MCC) and nanocrystalline cellulose (NCC) influence the growth, phenolic compound levels, and antioxidant activity of the plant when grown in vitro.
- - Results showed that certain concentrations of MCC and NCC improved plant growth and secondary metabolite production, with MCC at 1.5 g/L enhancing antioxidant activity, while NCC treatments had a negative effect on antioxidants.
