Drug–ingredient–gene target network, protein interaction network, and molecular docking of Yinqiao powder. (a) Drug–ingredient–gene target network of Yinqiao powder. The triangle (▲) is the drug of Yinqiao powder, the rectangle (■) is the main active ingredients of Yinqiao powder, the oval nodes (●) is the potential targets for treating COVID‐19 of Yinqiao powder. (b) Protein interaction network of Yinqiao powder. The size of the node represents the value of the degree (low values to small sizes). (c) Molecular docking. (d) Surface plasmon resonance (SPR) analysis of luteolin and ACE2 [Colour figure can be viewed at wileyonlinelibrary.com]
