Daun dewa (Gynura pseudochina) is a potential producer of a medicinally active compound. Several active compounds contained were steroid, saponin, flavonoid, tannin, and essential oils. The benefit of G. pseudochina as medicine includes anticoagulant (prevent blood clot) and blood liquefaction. The use of zeolite and sand as substrates in this study shall give information about the active compound in the plant. Thus, the objectives of this study were to know the effect of substrate towards the active compound and flavonoid contents, also to determine the effective substrate that leads to the higher activity of antioxidant and flavonoid contents in G. pseudochina. This study used an experimental method with a two-factor factorial, completely randomized design. The first factor was substrates, consist of zeolite and sand substrates. The second factor was the treatment of humic acid concentrations, 0 g/kg; 4g/kg; 8 g/kg; 12g/kg. There were a total of 24 units of experiment, which consist of 8 combinations of treatments with three replications each. The result showed that both zeolite and sand substrates affected the growth and antioxidant activity of G. pseudochina. Zeolite substrate enhanced the antioxidant activity, yet it did not increase the growth. Meanwhile, the sand substrate increased growth. The treatment of 8 g/kg humic acid in a zeolite substrate enhanced the antioxidant activity. The treatment of humic acid in both zeolite and sand substrates could be used to improve the growth and antioxidant activity in G. pseudochina.

Daun dewa (Gynura pseudochina)是一种药用活性化合物的潜在生产商。所含的几种活性化合物是类固醇、皂苷、类黄酮、单宁和精油。G. pseudochina作为药物的好处包括抗凝剂（防止血栓）和血液液化。在本研究中使用沸石和沙子作为基质应提供有关植物中活性化合物的信息。因此，本研究的目的是了解底物对活性化合物和类黄酮含量的影响，同时确定有效的底物导致假木瓜中抗氧化剂和类黄酮含量更高的活性。. 本研究使用了一种实验方法，采用双因素因子、完全随机设计。第一个因素是基质，由沸石和沙子基质组成。第二个因素是处理腐植酸浓度，0 g/kg；4克/公斤；8克/公斤；12克/公斤。实验共24个单元，由8个处理组合组成，每个处理3个重复。结果表明，沸石和沙底都影响了茯苓的生长和抗氧化活性。. 沸石底物增强了抗氧化活性，但没有增加生长。同时，砂基体增长加快。在沸石基质中处理 8 g/kg 腐殖酸增强了抗氧化活性。沸石和沙子基质中腐殖酸的处理可用于改善假花木的生长和抗氧化活性。
