摘要：

为开拓无色或淡色的植物提取液的附加价值,利用银杏叶提取液中的黄酮实现对羊毛和蚕丝织物的抗菌整理。首先采用乙醇/水提取法制备了含黄酮的银杏叶提取液(GBL-e),并通过高效液相色谱法考察GBL-e中的黄酮类型;然后使用GBL-e对织物进行抗菌整理,并通过吸附反应模型探究织物对GBL-e黄酮的吸附机制;最后研究2种织物的抗菌性能。实验结果表明,GBL-e中主要存在槲皮素、山奈酚和异鼠李素这3种黄酮类化合物;羊毛和蚕丝织物对黄酮的吸附过程符合Lagergren准二级动力学模型以及Langmuir和Freundlich吸附等温模型,且蚕丝织物对黄酮的吸附能力显著优于羊毛织物;经过GBL-e整理的2种织物均具有良好的抗菌性能。

Abstract:

Objective In order to further explore and enhance the added value of colorless or light-colored plant extracts in the field of textile functionalization, this study focuses on utilizing flavonoids derived from Ginkgo Biloba leaf extracts (GBL-e) to impart antibacterial properties to two fabrics (wool and silk fabrics). While much existing research emphasizes the dyeing potential of pigmented plant extracts, this work intentionally targets underutilized, low-color botanical resources that are rich in bioactive compounds, aiming to provide an eco-friendly and sustainable approach to fabric finishing, aligning with growing demands for green manufacturing processes. The research systematically evaluates the extraction, identification, adsorption behavior, and antibacterial efficacy of GBL-e flavonoids on wool/silk substrates, thereby offering a comprehensive strategy for valorizing plant waste and expanding the functional applications of natural extracts in fabrics.

Method Initially, the flavonoid-rich Ginkgo Biloba leaf extract (GBL-e) was prepared using an ethanol/water extraction technique. Following extraction, high performance liquid chromatography (HPLC) was employed to qualitatively and quantitatively identify the specific types of flavonoids present in GBL-e, offering critical insights into its composition. Subsequently, the two fabrics were subjected to functional finishing treatment using the as-prepared GBL-e solution. Throughout this finishing process, the adsorption behavior and binding mechanism of flavonoids onto the wool/silk substrates were rigorously examined using established adsorption reaction models, enabling a deeper understanding of the interaction kinetics and equilibrium characteristics. Finally, the antibacterial efficacy of the treated fabrics was evaluated to determine their potential for practical applications in bioactive fabrics.

Results The retention time of the HPLC spectrum of GBL-e was the same as that of that of the mixed standards (quercetin, kaempferol and isorhamnetin), which were 10.657 min, 23.288 min and 41.247 min, respectively, suggesting that these three flavonoids were present in GBL-e; After the determination of flavonoids of Ginkgo Biloba leaves collected in different seasons, it was found that although the flavonoid content of the leaves was the highest in June, but the flavonoid content of Ginkgo Biloba leaves in November did not decrease a lot, which indicated an additional value of Ginkgo Biloba fallen leaves. In the process of finishing protein fabrics with GBL-e, the flavonoid adsorption amount (Q_fla value) and dye-uptakes (E_t) and K/S curves of the two protein fabrics showed a gradual increase in the trend with the prolongation of the finishing time; moreover, by increasing the concentration of flavonoids in the finishing solution, the Q_fla,e values of the two fabrics also increased. In terms of kinetic modeling, the correlation coefficients of quasi-primary kinetics of flavonoid adsorption of GBL-e on the two fibers were poor, while the fitting correlation coefficient (r²) of quasi-secondary kinetics was above 0.99, so the quasi-secondary kinetics was more in line with the process of the adsorption of flavonoids on the protein fabrics. In terms of thermodynamic modeling, the Langmuir and Freundlich adsorption isothermal equations of flavonoids from GBL-e on both wool/silk fabrics reached r² values above 0.98, but the Langmuir isothermal adsorption equation had a higher r² value than that of the Freundlich isothermal adsorption equation. In the presence of the control fabrics only, the medium contained more of colonies in the medium decreased significantly in the presence of GBL-e finished protein fabrics, which implies that both GBL-e finished protein fabrics have significant antibacterial activity.

Conclusion The main chemical components in GBL-e quercetin, kaempferol and isorhamnetin; prolonging the finishing time and increasing the concentration of flavonoids contribute to the adsorption of flavonoids on the protein fabrics. The adsorption process of GBL-e on the protein fibers conforms to Lagergren's quasi second-order kinetic model, and the isothermal model of Langmuir and Freundlich adsorption. The GBL-e-finished wool/silk fabrics had good antibacterial activity.
