title: Citrinolactones A, B and C, and Sclerotinin C, plant growth regulators from Penicillium citrinum.
abstract: New plant growth regulators, named citrinolactones A (1), B (2) and C (3) and sclerotinin C (4), were isolated from Penicillium citrinum and their structures established by spectroscopic methods including 2D NMR. Compounds 1 and 4 increased root growth in proportion to their concentration from 3 to 300 mg/l. In contrast, 2 completely inhibited root growth at a concentration of 300 mg/l and 3 did not show any effect on root growth in a concentration range of 3-300 mg/l.
