Premna serratifolia L. est une espèce de plantes de la famille des Verbenaceae. On trouve l'espèce en Afrique, en Océanie, en Asie et dans quelques îles du Pacifique. À l'Île de France, on l’appelait arbre à la migraine parce qu’on pensait que l’application de ses feuilles au front soulageait les maux de tête. Elle s'appelle aussi Bois sureau à l'Île Maurice. Cette espèce peut être naturalisée ailleurs.

Compounds documented for Premna serratifolia across natural-product and food-composition databases — not just the ~150 nutrients on a classic label ("nutritional dark matter").
A DNA barcode is a short, standardised stretch of genes that works like a fingerprint — enough to tell one species from another. Below is the molecular trace Premna serratifolia has left across the world's sequence archives.

06Genome at a glanceCCDB
The complete instruction manualPremna serratifolia carries — its genome. We read it from three angles — how big it is, how the DNA is packed into chromosomes, and how completely it has been sequenced — and explain how to read each value as you go.
Chromosomes & ploidyhow the DNA is packaged
2n is the full chromosome count in a normal body cell; n is a gamete (egg or sperm), which carries half. Ploidy is how many complete chromosome sets each cell holds — 2× (diploid) is typical for animals, while higher levels (polyploidy) are common in plants. Click any value below to see the underlying records and sources.

How to read this: each dot is one detection of this species' DNA in an environmental sample. The confidence meter weighs how many independent studies and places back up the signal — one detection in one study is a hint; many across several studies is solid. Records dated before 2008 (when eDNA methods began) are treated as likely mislabeled and left off the map.
