Botaaniline kirjeldus
Alpi hanerohi on mitmeaastane rohttaim hanerohu perekonnast, sugukonnast ristõielised. Taim kasvab 10-80 cm kõrguseks. Juurmised lehed moodustavad kodariku. Lehed on tugevarootsulised, saagja servaga, karvased. Alpi hanerohul on nelja kroonlehega õied, õisik on tavaliselt lihtne, harvem harunenud, kobar. Vili on pikk ja sale kõde, milles on 20-20 või rohkemgi seemet. Vili on tavaliselt sirge, harvem kõver ja üle 1mm lai. Seemned asuvad kõdras ühes reas ja on tiivakestega. [1]

Levila
Alpi hanerohi levila paikneb Euroopa Alpides, Hispaanias, Araabias ja Ida-Aafrikas ning ulatub Skandinaaviasse, Lõuna-Gröönimaale ja Põhja-Ameerika kirdeosadesse. [2,3]

Toime ja kasutamine
Tuntud püsik ääristamiseks, kevadiseks peenralilleks ja kiviktaimlasse. Dekoratiivsuse säilitamiseks tuleb pärast taimede õitsemist neid pügada 4-5cm kõrguselt maapinnast ja kergelt mullata. 2-3 nädala pärast kasvab juurde ilus taimemass ja põõsas muutub kohevaks. Väga effektne on kasutada peenras koos tulpidega. [2] Taime kasutatakse molekulaar-bioloogiliste uuringute mudelorganismina sarnaselt müürilooga (Arabidopsis thaliana).  [3]

Alpi hanerohi sisaldab eeterlikku õli, mille koostisest on tuvastatud üle 50 komponendi. Taimel on mõõdukas antimikroobne ja antioksüdantset toime. [4]

Botanical Description
Alpine roc-kcress is a perennial herbaceous plant from the Arabis genus, belonging to the Brassicaceae family. The plant grows between 10–80 cm in height. The basal leaves form a rosette. The leaves are strongly petiolate, serrated, and hairy. The flowers of alpine rockcress have four petals, and the inflorescence is usually simple, occasionally branched, forming a raceme. The fruit is a long and slender silique containing 20 or more seeds. The fruit is usually straight, occasionally curved, and over 1 mm in width. The seeds are arranged in a single row within the silique and are winged. [1]

Distribution
The distribution range of alpine rockcress includes the European Alps, Spain, Arabia, and East Africa, extending to Scandinavia, southern Greenland, and the northeastern regions of North America. [2,3]

Effects and Usege
Alpine rock-cress is a well-known perennial used for border planting, as a spring flower in flower beds, and in rock gardens. To maintain its decorative appearance, the plants should be pruned to a height of 4–5 cm from the ground after flowering and lightly covered with soil. Within 2–3 weeks, new plant mass grows, making the shrub lush again. It is highly effective when planted alongside tulips in flower beds. [2] The plant is also used as a model organism in molecular biology research, similar to Arabidopsis thaliana. [3]

Alpine rock-cress contains essential oil, which has been found to consist of over 50 components. The plant exhibits moderate antimicrobial and antioxidant properties. [4]
