为了确定心房利钠肽是否存在于植物和动物中，它们对水和钠代谢很重要，检查了佛罗里达美人（德拉塞纳godsefiana）的叶和茎。126个氨基酸的心钠素（ANF）前体激素的N-端（氨基酸1 -98）、N-端中部（氨基酸31 - 67）和C-端（氨基酸99-126）均存在于该植物的叶和茎中。在叶和茎中，pro ANF 1-98、pro ANF 31-67和ANF样肽的浓度分别为120±20、123±21和129±20 ng/g植物组织和109±20、96±21和124±18 ng/g组织，与大鼠体内浓度相比，（196±40）、（192±28）和（189±15）ng/g组织，但高于对照组（P <0.05）。（P< 0.001），分别为4.3±1.4、4.1±1.2和3.9±1 ng/g。我们的结论是心房利钠肽样激素系统是存在于植物王国以及在动物王国。
To determine if atrial natriuretic peptides are present in plants as well as animals, where they are important for water and sodium metabolism, the leaves and stems of the Florida Beauty (Dracena godseffiana) were examined. The N-terminus consisting of amino acids (aa) 1–98 (ie, pro ANF 1–98), the mid portion of the N-terminus (aa 31–67; pro ANF 31–67), and C-terminus (aa 99–126; ANF) of the 126 aa atrial natriuretic factor (ANF) prohormone were all present in the leaves and stems of this plant. The concentrations of pro ANF 1–98, pro ANF 31–67 and ANF-like peptides of 120±20, 123±21, and 129±20 ng/g of plant tissue in leaves and 109±20, 96±21, and 124±18 ng/g of tissue, respectively, in the stems were lower (P< 0.05) than their concentrations in rat (Rattus norvegicus) heart atria of 196±40, 192±28, and 189±15 ng/g of tissue respectively, but higher (P< 0.001) than their respective concentrations of 4.3±1.4, 4.1±1.2, and 3.9±1 ng/g of rat heart ventricular tissue. We conclude that the atrial natriuretic peptide-like hormonal system is present in the plant kingdom as well as in the animal kingdom.
