Introduction: A medicinal plant from Central Kalimantan, Spatholobus littoralis Hassk., with a local name bajakah tampala, has long been used to treat gout or uric acid disease. This study aimed to develop the optimum conditions of xanthine oxidase (XO) activity, phytochemical screening, and to obtain the antigout activity of S. littoralis Hassk. Methods: Before performing the phytochemical screening, we performed a simplicia maceration with water and 70\% ethanol solvents. The development of the optimum conditions for XO was carried out using the Response Surface Methodology (RSM) combined Box-Behnken Design (BBD). Toxicity assay (LC50) on both extracts was assessed by BSLT (Brine Shrimp Lethality Test). The two extracts were then evaluated for antigout activity. Results: The yield of 70\% ethanol extract (11.24\%) was higher than the aqueous extract (7.29\%). The phytochemical screening on the simplicia and the two extracts positively contained steroids, flavonoids, saponins, and tannins. The optimum conditions of XO activity were temperature of 20 {\textcelsius}, pH of 8.0, and xanthine concentration of 1.40 mM. The toxicity of the 70\% ethanol extract (LC50 662.25 mg/L) was stronger than the aqueous extract (LC50 774.68 mg/L). Moreover, the 70\% ethanol extract (IC50 224.14{\textpm}8.62 mg/L) showed higher XO inhibition than the water extract (IC50 348.83{\textpm}4.85 mg/L). Lineweaver-Burk plot analysis showed that 70\% ethanol and water extracts inhibited XO competitively with the inhibition constant (KI) of 272.68 mg/L and 378.44 mg/L, respectively. Conclusion: This preliminary study can be a reference that S. littoralis Hassk. is potentially an antigout.

Indonesia is a tropical country with mega-biodiversity. Several medicinal plants locally have been recognized for their anti-inflammatory properties and are traditionally used to help treat respiratory diseases. Chronic obstructive pulmonary disease (COPD) is one of the diseases known as the high cause of death globally, and one of the treatment efforts is by using anti-inflammatory drugs. In developing alternative remedies for COPD, this review summarizes the potential of Indonesian medicinal plants and their ingredients known to have an anti-inflammatory activity to develop alternative remedies for COPD. Primarily, we focus on the medicinal plants that have been scientifically proven to pose some biological activities, such as legetan warak (Adenostemma lavenia), celery (Apium graveolens), pegagan (Centella asiatica), kenikir (Cosmos caudatus), and kersen (Muntingia calabura). This review is expected to provide more information about Indonesian medicinal plants and their potencies to be developed as COPD herbal medicine and, further, as a treatment to help patients suffering from coronavirus disease (COVID-19).
