Abstract

Eleutherine palmifolia (L.) Merr is one of the horticultural that can be used as a medicinal plant. It was contained flavonoid and anthocyanin. The production of bioactive content on E. palmifolia was affected by light intensity. This experiment was conducted at Sukoharjo village, District of Ngaglik, Region of Sleman, Yogyakarta, Indonesia, from May to October 2020. The experiment was laid out with a single factor in a randomized block design (RBD). Three treatments were given, namely no shading, shading 55%, and shading 75%. Each treatment was repeated five times. The result showed that shading gave different effect on physiology and yield of E. palmifolia. Shading 55% and 75% produced the number of tiller and bulb of E. palmifolia lower than no shading. The fresh bulb weight of E. palmifolia in the range between 34.9 - 38.5 g plant-1. The chlorophyll a, chlorophyll b, chlorophyll total, chlorophyll a/b ratio, and chlorophyll b/a ratio content on E. palmifolia^s bulb were not affected by different shading given. Shading 75% gave the highest total flavonoid and anthocyanin content of E. palmifolia^s bulb was 19.77% and 28.10% than no shading, respectively.
