| dc.description.abstract | A research has been conducted on the effect of extraction methods of Bawang Dayak
(Eleutherine palmifolia (L.) Merr) against TLC profiles and sunscreen activity. The study aims
to determine the effect of extraction methods against yield, TLC profile, and sunscreen
activities.The Sample was extractedusing several extraction methods (maceration, reflux, and
soxhlet)with different polarity solvent(n-hexane, ethyl acetate, ethanol, dan methanol) and
single solvent (methanol), respectively. Yield value obtainedmethanol extract (single solvent)
are 8.027% maceration, 6.943% reflux, and 10.694%soxhlet.N-hexane extract are 1.572%
maceration, 1.251% reflux, 2.146% reflux. Ethyl acetate extract were 2.141% maceration,
0.966% reflux 1.681% soxhlet. Ethanol extract are 3.537% maceration, 3.280% reflux, 3.974%
soxhlet. Methanol extract are 1.999% maceration, 2.553% reflux, 2.682% soxhlet.Furthermore,
the determination of the TLC profile from all methods using comparisons N-hexane: ethyl
acetate among other;N-hexane extract was 6-7 spots (3:1), ethyl acetate extract was 9
spots(2:1), methanol extract (single solvent) was 8 spots (2:1). Determination TLC profile using
comparisons chloroform:methanoleluent namely; ethanol extract was 9 spots (7:1), methanol
extract was 5 spot (2:1), and methanolextract (single solvent)was 8 spots (5:1).Sunscreen
