Table 2 The biological applications of OP

1

Exhibited good DPPH radical-scavenging ability

[26]

2

Exhibited antioxidant, α-amylase, and α-glucosidase inhibitory activities in vitro

[27]

3

Induce different secondary conformation changes of gelatin during complex coacervation

[28]

4

Responsible for the hypoglycemic activity

[31]

5

Anti-fatigue

[29]

6

Enhancing immune response including phagocytic activity, spleen index, splenocytes proliferation, and control immune responses through cytokine production

[30]

7

Synthesized ZnO nanofilms contains okra mucilage, showed high antibacterial activity against S. aureus than E. coli

[34]

8

Exhibited significant in vitro antioxidant activity

[16]

9

Possess therapeutic functions on metabolic diseases by the inhibition of LXR and PPAR signaling

[32]

10

Reduced the proliferation significantly but improved the cell viability
