The Utilization of Sweet Potato Tops (Ipomoea batatas) and Red Santan Flower (Ixora coccinea) Extracts as Alternative Marker Ink

Abstract

INTRODUCTION

Sweet potato tops and red santan extracts were tested to produce an alternative ink. The researchers used organic materials than to utilize the original components that may harm the users of markers.

METHODS

Sweet potato tops and red santan flowers obtained from San Pablo City, Laguna were extracted by blendor method and pounded using a mortar and pestle, respectively. A total of six treatments were prepared with varying concentrations (SP1, SP2, SP3, SP4, RS1, RS2). The formulated setups were dropped in a clean paper using a pipettor and observed the difference of each solution that was produced.

RESULTS

Descriptive analysis was used for studying the data obtained from the experiment, such as the time of drying and the time produced by the setups in order to determine the difference of each. Each setup, (SP1, SP2, SP3, SP4, RS1, RS2) have different time of drying and color retention.

DISCUSSIONS

Treatment SP3 (with 23mL sweet potato tops extract, 3mL 50% ethyl alcohol, and 5 pinches of cornstarch) was recorded the most efficient, based on time it dried up (in a span of 30 minutes and 10 seconds), and its color retention {darker green).
