Pohon ulin (Eusideroxylon zwageri) menjadi salah satu pohon yang
dilindungi dan terancam punah. Kandungan senyawa metabolit sekunder pada
pohon ulin diduga memiliki ketahanan tinggi terhadap serangan hama seperti rayap.
Penelitian ini bertujuan mengukur kadar fenolik total dan kadar flavonoid total dari
15 aksesi kayu ulin asal Kalimantan. Simplisia kayu ulin diuji kadar air, serta
ekstrak etanol kayu ulin diuji kadar fenolik total dan flavonoid totalnya. Data
dianalisis menggunakan uji one-way ANOVA, uji lanjut Tukey, dan Analisis
Komponen Utama (AKU). Hasil penelitian menunjukkan kadar air dari 15 aksesi
mempunyai rentang nilai 4,85 – 9,36 % (b/b). Kadar fenolik total dan flavonoid
total tertinggi yaitu pada aksesi XVI.E.197 dan IX.C.7 secara berturut-turut sebesar
700,55 mg GAE/g dan 16,81 mg QE/g. Hasil skor plot AKU menunjukkan
klasterisasi terbagi menjadi tiga kelompok yaitu rendah, sedang, dan tinggi. Dengan
demikian, perlu dilakukan uji lanjutan untuk menganalisis senyawa spesifik yang
terkandung dan melakukan uji aktivitas ekstrak kayu ulin sebagai anti rayap. The ulin tree (Eusideroxylon zwageri) is one of the protected and endangered
trees. The content of secondary metabolite compounds in ulin trees is thought to
have high resistance to pests such as termites. This study aims to measure the total
phenolic content and total flavonoid content of 15 ironwood accessions from
Kalimantan. Simplisia of ulin wood was tested for moisture content, and ethanol
extract of ulin wood was tested for total phenolic content and total flavonoids. Data
were analyzed using one-way ANOVA test, Tukey test, and Principal Component
Analysis (PCA). The results showed that the moisture content of the 15 accessions
ranged from 4,85 – 9,36% (w/w). The highest total phenolic and total flavonoid
levels were in accessions XVI.E.197 and IX.C.7 at 700,55 mg GAE/g and 16,81
mg QE/g, respectively. The results of the PCA plot score show that the
clusterization is divided into three groups, namely low, medium, and high. Thus, it
is necessary to conduct further tests to analyze the specific compounds contained
and test the activity of ironwood extracts as termite repellents.
