Abstract:
Sungkai (Peronema canescens Jack.) from South Kalimantan, Indonesia, are used to treat fever
and increase body immunity. This study aims to establish pharmacognostic standards that
include specific and non-specific parameters and determine the antioxidant activity of
methanol extract of P. canescens leaves. P. canescens leaves were taken from South
Kalimantan, Indonesia, and were processed into simplicia according to the standards. The
extraction was carried out using methanol and maceration techniques, then investigated
covering specific and non-specific parameters. Antioxidant testing was carried out by TLC and
DPPH assay. The results showed that drying shrinkage was 7.43%, total ash content was
4.10%, and acid-soluble ash content was 0.23%. Simplicia of P. canescens leaves was green
in color, had a strong taste, and a characteristic odor, as well as some cell parts from
microscopic observations. This study provides an overview of P. canescens, including specific
and non-specific parameters that meet herbal medicine standards.
