Phytoserotonin

Updated: 2026-07-22

Overview

Plant 5-Hydroxytryptamine (5-HT), commonly known as serotonin, is a biologically active compound found in various plant species. It functions as a neurotransmitter and signaling molecule, influencing plant growth, development, and stress responses. Unlike its role in animals, where it primarily affects mood and behavior, 5-HT in plants is involved in physiological processes such as root development, flowering, and defense mechanisms against pathogens. Research has shown that 5-HT accumulates in plants under stress conditions, such as drought or pathogen attack, suggesting its role in stress adaptation. Its presence has been documented in bananas, pineapples, and walnuts, among other plants. The study of plant 5-HT offers insights into plant physiology and potential applications in agriculture.

Physical and Chemical Properties

Main Applications

Plant 5-Hydroxytryptamine is primarily used in agricultural research and plant physiology studies. It serves as a key compound in understanding plant stress responses and growth regulation. Researchers utilize 5-HT to investigate its role in root development, flowering, and defense mechanisms against environmental stressors. In addition to research, 5-HT has potential applications in crop enhancement. By modulating serotonin levels, scientists aim to develop plants with improved stress tolerance and yield. The compound is also studied for its interactions with other plant hormones, offering a broader understanding of plant signaling networks.

Safety and Storage

While plant 5-Hydroxytryptamine is not highly toxic, it should be handled with care to avoid inhalation or direct contact with skin and eyes. Proper personal protective equipment, such as gloves and lab coats, is recommended when working with the compound. Storage conditions are critical to maintaining the stability of 5-HT. It should be kept in a cool, dry place, away from light and moisture. Sealed containers under inert gas can further preserve its quality. Long-term storage at low temperatures (e.g., -20 °C) is advisable for bulk quantities to prevent degradation.

B2B Procurement Guide

When procuring plant 5-Hydroxytryptamine, B2B buyers should prioritize suppliers who provide detailed certificates of analysis (CoA) and purity verification. The reference price range is approximately $100-$500 per gram, depending on purity and supplier reliability. Bulk purchases may offer cost advantages, but buyers should ensure proper storage facilities are available. Key procurement considerations include supplier reputation, compliance with regulatory standards, and the availability of technical support. Buyers should also verify the compound's intended use compatibility, as different purity grades may be required for research versus industrial applications.
