Emodin, an anthraquinone extracted from aloe vera is used to treat liver injuries, necrosis, inflammation, and kidney diseases and to treat carcinoma. Studies report that aloe-emodin exhibits antiviral properties against enveloped viruses like influenza A virus and herpes simplex virus. It is also shown to obstruct attachment, entry, and replication of the influenza virus (Gansukh et al. 2018). The anticancer properties of aloe-emodin have been found to inhibit cancer cells like hepatoma cells, glioma, and carcinoma cells. It also possesses strong anti-proliferative and antineoplastic reaction on cancer cells due to its apoptotic nature (Chou and Liang 2009).

Aloe vera is a plant resource that contains more than 200 different biologically active substances with moisturizing, anti-inflammatory, immunomodulatory, antibacterial, antifungal and antitumor properties (Sahu et al., 2013). Researchers have also pointed out that aloe vera has fewer adverse effects on human health compared with other herb (Mondal et al., 2021). Aloe vera rinds, rich in anthraquinones (Lai et al., 2016), become waste in the production of skin care products. Aloe anthraquinone (AA) is an antibacterial ingredient in aloe vera rinds that can kill resistant bacteria produced by antibiotics (Reynolds & Dweck, 1999). Aloin A, Aloin B, and Aloe-Emodin are the main components that exert pharmacological effects (Patel et al., 2012). Xu & Deng used citric acid (CA) as a crosslinking agent to graft AA onto cotton fabric, and the antibacterial test results showed that the antibacterial rate against E. coli and S. aureus were 91% and 93.7%, respectively (Xu & Deng, 2011). Nadiger & Shukla used 1, 2, 3, 4-butanetetracarboxylic acid and methanol extract of aloe vera to finish silk fabric. After five washing cycles, the antibacterial rate against S. aureus and K. pneumoniae were still higher than 92% and 90%, respectively (Nadiger & Shukla, 2015); however, there was an imperfect antibacterial effect and washing resistance. Therefore, it is necessary to explore an efficient process to endow AA-treated silk fabrics with a higher antibacterial effect and washing resistance.

By combining UV and FTIR spectral analysis with the total polyphenol and flavonoid contents, it can be inferred that polyphenols and flavonoids were the main compounds in AVD. Based on existing studies on the composition of AVRs, AVD may contain Aloesin, 7-O-Methylaloeresin A, Aloe-emodin, Aloin A, and Aloin B (Figure 4, Lai et al., 2016).
