| Tóm tắt: | Indigofera cassioides Rottl. ex Bl. and Indigofera suffruticosa Mill., which
are widely distributed in Lam Dong province, serve as a natural source of
indigo color. Indigo powder, known for its inherent indigo color, has been
used by humans for dyeing and medicinal purposes for a long time.
However, no global research has investigated the extraction efficiency of
indigo powder and the indigotin content from these two indigo species.
This study aimed to evaluate the extraction efficiency of indigo powder and
measure the indigotin content in both the powder and fresh leaves of these
species in Lam Dong. The indigo powder was obtained using the
maceration extraction method, and the indigotin content was determined
through spectrophotometry using a JASCO V-730 spectrophotometer (UV-
VIS). The results showed that the efficiency of extracting and collecting
indigo powder from these two species was 4.61 ± 0.30% for I. cassioides
and 4.23 ± 0.92% for I. suffruticosa. The indigotin content in I. cassioides
indigo powder was found to be 2.83 ± 0.467%, while in I. suffruticosa
indigo powder, it was 8.80 ± 2.12%. This corresponds to an indigotin
content in fresh leaves of I. cassioides and I. suffruticosa samples of 0.13 ±
0.02% and 0.37 ± 0.09%, respectively. |
