(Hua) Engl. ex K. Krause, locally known as (bitter greens) or , is a widely consumed wild vegetable and traditional herbal medicine in western Yunnan. Despite its local significance, its nutrient composition and bioactive properties have not been investigated. This study aims to determine the nutritional content and evaluate the antioxidant and anti-inflammatory activities of the aerial parts extracts of . The levels of protein, amino acids, vitamins, and minerals were measured and compared to those of common vegetables. The results showed that contains 16 amino acids, with a total content of up to 19.13 g/100 g, including 3.0 g/100 g of lysine. In vitro evaluations of its antioxidant and anti-inflammatory activities demonstrated that the ethanolic extract exhibited low cytotoxicity against mouse RAW 264.7 murine macrophages cell line at concentrations of 0-120 μg/mL. The IC for nitric oxide (NO) scavenging activity was 72.7 ± 7.43 μg/mL, showing dose dependence. Additionally, the ethanolic extract also exhibited ABTS· scavenging capacity and total antioxidant capacity. These findings suggest that is rich in carbohydrates, fat, dietary fiber, and amino acids. It also contains various bioactive substances, supporting its traditional practices for both medicinal and dietary purposes by local people. has the potential to be developed into a novel anti-hypertensive food, nutraceutical, or dietary supplement in western Yunnan and neighboring regions, promoting local development.
华泽兰（英文名源自K. Krause，当地称为“苦青菜”或“”）是滇西广泛食用的野生蔬菜和传统草药。尽管它在当地具有重要意义，但其营养成分和生物活性尚未得到研究。本研究旨在测定华泽兰地上部分提取物的营养成分，并评估其抗氧化和抗炎活性。测定了蛋白质、氨基酸、维生素和矿物质的含量，并与常见蔬菜进行比较。结果表明，华泽兰含有16种氨基酸，总含量高达19.13克/100克，其中赖氨酸含量为3.0克/100克。对其抗氧化和抗炎活性的体外评估表明，乙醇提取物在0 - 120微克/毫升的浓度下对小鼠RAW 264.7巨噬细胞系表现出低细胞毒性。一氧化氮（NO）清除活性的IC50为72.7±7.43微克/毫升，呈剂量依赖性。此外，乙醇提取物还表现出ABTS·清除能力和总抗氧化能力。这些发现表明，华泽兰富含碳水化合物、脂肪、膳食纤维和氨基酸。它还含有多种生物活性物质，支持当地居民将其用于药用和饮食的传统做法。华泽兰有潜力在滇西及周边地区开发成为新型抗高血压食品、营养保健品或膳食补充剂，促进当地发展。
