species have been used as herbal medicines in traditional Asian medicine. One of the species that has the potential as a medicinal plant and is still limited in its studies is . This study investigated the effects of drying methods, namely, freeze drying (FD) and hot air drying (HAD), on bioactive compounds, phenolics, flavonoids, and antioxidants in leaves and stems. The content of bioactive compounds in . leaves and stems was identified with gas chromatography-mass spectrometry (GC-MS) analysis. In addition, the antioxidant activity of was also measured. The results of GC-MS on contain major bioactive compounds including gamma.-Sitosterol, Glutinol, Friedelan-3-one, Squalene, Ergost-5-en-3-ol, (3.β.)-, Erythritol, and Neophytadiene. The main component identified in the leaf and stem extracts of is gamma-sitosterol (± 15%), which shows anticancer and antidiabetic effects. The antioxidant activity in with the FD method was higher than that with the HAD method. This study suggests that FD was considered appropriate and should be used to maintain the content of important bioactive compounds and antioxidant activity in . These findings suggest that further research and development of bioactive compounds essential for their pharmacological properties in may be warranted, with the potential for developing new drugs.

The white spot syndrome virus (WSSV), considered the deadliest pathogen impacting Penaeid shrimp (Penaeus monodon), remains worrisome for the global shrimp industry due to its extreme virulence and mortality rate of up to 100%. To date, there has been no breakthrough in effective antivirals or vaccines that can mitigate the financial damage caused by the pathogen. The distinctive structure of VP28 facilitates its role as a trimer, serving as the primary envelope protein of WSSV.
