Abstract

Background and Objective: Andrographis paniculata (Burm.f.) Nees is a herb that act as agents of anti-inflammatory, reduce fever and alleviate respiratory symptoms. However, there is an inadequacy of information on the influence of light quality on the growth and accumulation of secondary metabolites in A. paniculata. Therefore, this research aimed to study the effects of LED lights on growth and bioactive compounds in A. paniculata. Methodology: The A. paniculata seeds were grown in a 104-hole seedling tray, and then 30-day-old seedlings were transplanted into a grow bag measuring 8 × 15 cm. The seedlings were grown in a greenhouse under natural light and supplemented with different LED lights from 18.00 to 20.00 p.m., including fluorescent (control), blue, and red LED lights. The light intensity was 100 µmol
