We present a genome assembly from a specimen of Ballota nigra (black horehound; Tracheophyta; Magnoliopsida; Lamiales; Lamiaceae). The genome sequence is 1186.8 megabases in span. Most of the assembly is scaffolded into 11 chromosomal pseudomolecules. Three mitochondrial chromosomes were assembled, with lengths of 148,17, 121,67 and 125,74 kilobases. The chloroplast genome has been assembled and is 151.91 kilobases in length. more...

Ballota nigra, also known as black horehound is a common medical herb used in folk medicine around the world. First reported mentions of its medical properties and use goes as far as the 13th century. The use of black horehound depends on regions and countries. It is used mostly to treat e.g. mild sleep disorders, nervousness, upset stomach, wound healing. It can be used as an anti-inflammatory, antibacterial, antiprotozoal, antifungal drug. Moreover, it has been reported as a potential cancer drug. This extensive usage is particularly interesting for us. The aim of this review is to present available data on B. nigra pharmacological effects and known traditional uses gathered from a wide range of scientific articles published in 1997–2020. more...

The volatile component composition of leaves and flowers for Ballota nigra subsp. anatolica P.H. Davis that were collected between 2015 and 2016 from Çamlıca provice of Kütahya city during three different vegetation periods as pre-bloom, bloom and post flowering were determined by gas chromatography mass spectroscopy (GC-MS) after solid phase micro extraction (SPME). 59 different volatile oil components were determined of Ballota nigra subsp. anatolica. As main components, Hexenal (17.60%), germacrene D (6.70%) and β-caryophyllene (8.80%) were found during pre-blooming period, also Hexenal (21.16%), germacrene D (7.77%) and β-caryophyllene (10.03%) in blooming period and Hexenal (15.88%), germacrene D (7.60%) and β-caryophyllene (9.48%) in post-flowering period.
