Plant growth regulators (PGRs) play a pivotal role in increasing vegetable productivity, but they have many drawbacks that can include health and safe concerns of consumers. In this study, the plant growth regulators (PGRs) contents of 111 Brassica juncea (L.) Czern. samples collected from six main suburban areas of Hanoi, Vietnam, were determined by liquid chromatography-electrospray tandem mass spectrometry. Results showed the presence of PGRs residues in 83 analyzed samples (74.77%). Eight PGRs, including Indole-3-acetic acid (IAA), Indole-3-butyric acid (IBA), Indole-3-carboxylic acid (ICA), 3-Indolepropionic acid (IPA), Gibberellin A (GA), Gibberellin A (GA), Gibberellin A (GA) and Trans-zeatin (tZ), were found in B. juncea with the average residues dropped in the range of 0.04 and 0.65 mg kg. GA was considered as the most popular PGR applying in vegetable production in the investigated areas. Notably, the concentrations of gibberellins were higher than the regulations in vegetables and fruits in Europe, USA and Japan. This might be the potential health risks to consumers and environmental pollution, which necessary to be controlled with consideration of residue regulations.
植物生长调节剂 (PGRs) 在提高蔬菜产量方面发挥着关键作用，但它们存在许多缺点，包括消费者的健康和安全问题。在这项研究中，采用液相色谱-电喷雾串联质谱法测定了从越南河内六个主要郊区采集的 111 份芥菜 (Brassica juncea (L.) Czern.) 样本中的植物生长调节剂 (PGRs) 含量。结果表明，在 83 个分析样本中存在 PGRs 残留 (74.77%)。发现 8 种 PGRs，包括吲哚-3-乙酸 (IAA)、吲哚-3-丁酸 (IBA)、吲哚-3-羧酸 (ICA)、3-吲哚丙酸 (IPA)、赤霉素 A (GA)、赤霉素 A (GA)、赤霉素 A (GA)和玉米素 (tZ)，在芥菜中存在，其平均残留量在 0.04 至 0.65mg/kg 范围内。GA 被认为是在所调查地区蔬菜生产中应用最广泛的 PGR。值得注意的是，赤霉素的浓度高于欧洲、美国和日本蔬菜和水果的规定。这可能对消费者的健康和环境造成潜在风险，需要考虑残留规定加以控制。
