Epidemiological studies have shown an in-verse correlation betweendiets rich in po-lyphenols, flavonoids and reduced risk of cardiovasculardisease. These associationswere mainly ascribed to the antioxidant, antiaggregation and anticholesterol capa-city of polyphenols. This association has been explained that atherogenesis is ini-tiated by hypercholesterol, lipid peroxida-tion and hyper aggregation platelet. The research was carried out to evaluate anti-oxidant, anticholesterol and antiaggrega-tion activities of methanol extract and frac-tions of black tea (Camelia sinensis). To evaluate antioxidant activity of methanol extract and fractions were compared with (-)-Epigallocatechine 3-gallate (EGCG), an-ticholesterol activity were compared with simvastatin and antiaggregation activity were compared with aspirin. Antioxidant activity using the 1,1-diphenyl-2-picryl-hy-drazyl (DPPH) free radical scavenging acti-vity at two concentrations 100 µg/mL, 50 µg/mL and anticholesterol was cholesterol oxidase activity at two concentrations 0.005 µg/mL, 0.0025 µg/mL, the antiag-gregation activity used epinephrine (EPN)agonist at two concentrations 300 μM, 75 μM and one concentration 37.1 µg/mL of methanol extract and fractions of black tea. To know the difference of treatment, the data were analysed using Analysis of Variance (ANOVA) and be continued Dun-can’s new multiple range test. The results showed that DPPH scavenging activity were high (88.59-93.556%), the anticho-lesterol showed high activity (93.663-97.434%) and the antiaggregation sho-wed low up to high activity (79.967-4.31%). Using Duncan’s new multiple ra-nge test showed that anti-oxidant activity were not different among extract and fractions of black tea,the highest anti-cholesterol activity was black tea extract 0.005 µg/mL (97.434%) and the highest antiaggregation activity was ethyl acetate fraction on 75 μM EPN agonist (4.310 %), water fraction 37.1 µg/mL with 300 μM EPN agonist (21.833%).

In the course of our continuing search for novel paralytic compound from Indonesian plants, the methanol extract of the stem bark of Erythrina variegata (Leguminosae) showed significant paralytic activity against the third instar larvae of silkworm (Bombyx mori). The purposes of this research were isolation and structural elucidation of paralytic compound from the stem bark of E. variegata. Using the paralytic activity following the separation, the methanol extract was separated by combination of column chromatography to yield prenylisoflavone, warangalone. The chemical structure of warangalone was identified based on spectroscopic evidence and comparison with the previous reported. The paralytic activity of warangalone showed weak activity against the third instar larvae of silkworm (B. mori).

In the course of our continuing research for novel antimalarial agent from Indonesian plants, the methanol extract of the Erythrina variegata leaves showed significant antimalarial activity against Plasmodium falciparum strain K1 in vitro with IC50 6.8 μg/mL. The methanol extract was separated by using variety of chromatography techniques. The chemical structure of an antimalarial compound was determined on the basis of spectroscopic evidence and compared to previous data then this compound is identified as a pentacyclic triterpenoid oleane derivative, namely 3,22,23-trihydroxy-oleane-12-ene. The pentacyclic triterpenoid, 3,22,23-trihydroxy-oleane- 12-ene showed antimalarial activity against 3D7 and K1 strains with IC50 4.3 μg/mL and 24 μg/mL, respectively. These results strongly suggested that E. variegata is a promising sources of antimalarial agents.

Dadap ayam (Erythrina variegata) secara tradisional dikenal oleh masyarakat lokal sebagai obat antikanker. Bagian tumbuhan ini yang biasa digunakan sebagai pengobatan adalah daun, tetapi kandungan senyawa kimia aktif biologisnya belum banyak dilaporkan. Pencarian komponen aktif yang terdapat di dalam tumbuhan E. variegata sangat penting sebagai nilai tambah untuk bahan obat herbal antikanker. Tujuan penelitian ini adalah untuk mengetahui senyawa yang beraktivitas antikanker dari bagian daun dan kulit batang E. variegata secara in vitro terhadap sel kanker payudara T47D. Penelitian dilakukan dengan cara ekstraksi metanol dan fraksionasi dari daun serta kulit batang E. variegata yang dipandu dengan uji antikanker secara in vitro menggunakan metode Sulforhodamin B (SRB). Selanjutnya, fraksi aktif dipisahkan komponen-komponennya dengan kombinasi kolom kromatografi yang dipandu dengan uji antikanker secara in vitro, diperoleh tiga senyawa aktif (1-3). Struktur kimia senyawa aktif (1-3) ditetapkan berdasarkan data spektroskopi dan perbandingan data dari senyawa yang berhubungan dari penelitian sebelumnya, dan diidentifikasikan sebagai turunan steroid (1-3). Senyawa (1-3) memperlihatkan aktivitas antikanker secara in vitro terhadap kanker payudara T47D dengan IC50 masing-masing 6,5; 5,3; dan 3,2 ?g/ml. Daun dan kulit batang E. variegata menunjukkan sumber bahan antikanker payudara.Kata kunci: antikanker, Erythrina variegata, sel kanker payudara T47D
