Hierba vaquera

Appearance

The Scrophularia sambucifolia, or "Hierba vaquera" has opposite leaves, at least the core, rarely alternate higher. Racemiformes or paniculiformes inflorescences, terminals, with partial inflorescence whose main and lateral axes end in a flower, occasionally reduced to axillary solitary flowers tions.

Naming

Scrophularia sambucifolia L. subsp. sambucifolia

Distribution

Iberian peninsula, Morocco, Ocidental Mediterranic regions.

Habitat

Wet places, usually near the banks of water lines, preferably in deep soils of neem or calcareous.

Uses

The phenolic fractions of aerial part of Scrophularia frutescens and S. sambucifolia (Scrophulariaceae) showed a potent antibacterial activity. Ferulic, isovanillic, p-hydroxycinnamic, p-hydroxybenzoic, syringic, caffeic, gentisic and protocatechuic acids were isolated from S. frutescens and ferulic, p-coumaric, vanillic, p-hydroxibenzoic and syringic acids were isolated from S. sambucifolia. Since phenolic acids have been shown in the literature to exert an antibacterial effect, the presence of these compounds in the two plants explains their antibacterial activity.
