TL;DR: During the screening of antimalarial substances, the 80% EtOH extract from the outer bark of Ochna integerrima Merr.
Abstract: During the screening of antimalarial substances, the 80% EtOH extract from the outer bark of Ochna integerrima Merr. (Ochnaceae) was shown to have a good anti-malarial activity (IC50 value: 6.5 microg/mL) whereas extracts from the inner barks of O.integerrima showed no antimalarial activity. Biflavanone (1), which had not been found previously from a natural plant source, was isolated as a potent antimalarial active ingredient (IC50 value: 80 ng/mL) from the extract of the outer barks. The stereoisomer of 1 ( = compound 2) was also isolated from this plant; however, its activity was significantly lower than that of 1.

TL;DR: The effects of plant growth regulators and their concentrations on the induction of somatic embryogenesis and shoot organogenesis from leaf and shoot explants of O. integerrima are studied for the first time.
Abstract: Ochna integerrima is a medicinal and ornamental plant in Southeastern Asia. It has been listed as a rare and endangered species in China. Here we studied the effects of plant growth regulators and their concentrations on the induction of somatic embryogenesis and shoot organogenesis from leaf and shoot explants of O. integerrima for the first time. Cytokinins played a crucial role in somatic embryogenesis and shoot organogenesis. Among them, a higher concentration of thidiazuron (10.0–15.0 μM TDZ) could induce both somatic embryogenesis and adventitious shoot formation whereas low concentrations of TDZ (5.0 μM) could only induce adventitious shoots. However, 6-benzyladenine (BA at 5–15 μM) could only induce adventitious shoots. Shoot explants induced more adventitious shoots and somatic embryos than leaf explants when cultured on medium with the same concentration (5–15 μM) of TDZ or 15 μM BA. Medium containing 0.5 μM α-naphthaleneacetic acid and 8 μM indole-3-butyric acid and 0.1% activated charcoal could induce adventitious roots within 1 month. An efficient mass propagation and regeneration system has been established.

TL;DR: Two new biflavonoids were isolated from the stem bark of Ochna integerrima, together with five known compounds, and the structures of 1 and 2 were determined by spectral data interpretation.
Abstract: Two new biflavonoids, namely, 6‘ ‘‘-hydroxylophirone B (1) and 6‘ ‘‘-hydroxylophirone B 4‘‘‘-O-β-glucoside (2), were isolated from the stem bark of Ochna integerrima, together with five known compo...
