H₂S被认为是细胞内第三种气体信号分子,在植物体内,参与植物生长发育、增强生物以及非生物抗逆性,延缓植物衰老的多种生理过程。在动物体内,对神经系统有调节作用,还可舒张血管平滑肌,降低血压。 在Fe³⁺(作为氧化剂)存在的强酸性条件下,硫化氢与N,N-二甲基对苯二胺反应生成蓝色的亚甲蓝,亚甲蓝在665nm处有最大吸收峰,故可根据亚甲蓝生成的量来计算植物组织中的H₂S的含量。
H₂S is considered the third gas signaling molecule in cells. In plants, it participates in various physiological processes, including growth and development, enhancement of biotic and abiotic stress resistance, and delay of senescence. In animals, it plays a regulatory role in the nervous system, relaxes vascular smooth muscle, and reduces blood pressure. Under strongly acidic conditions in the presence of Fe³⁺ (as an oxidizing agent), hydrogen sulfide reacts with N,N-dimethyl-p-phenylenediamine to form blue methylene blue, which has a maximum absorption peak at 665 nm. Therefore, the H₂S content in plant tissues can be calculated based on the amount of methylene blue generated.
