Angelique des Açores

zwart zaad is van Melanoselinum
Nog eens een bezoekje gebracht aan de bijzondere medicinale plantentuin van Daoulas, daar bloeit nu ook de Melanoselinum decipiens, ook Angelique des Açores en Zwarte peterselie genoemd. Ondanks die namen wordt de plant niet als voeding gebruikt. Het is een vaste plant afkomstig van Madeira. Vormt een   stengel (stam) met grote diep ingesneden bladeren die iets overhangen. Oudere planten lijken op parapluvormige boompjes. Kan tot 250 cm hoog worden.
Jonge bladeren zijn aanvankelijk donkerrood maar worden later frisgroen.

Na enkele jaren gaat de plant bloeien met grote bloemschermen van kleine roze/witte bloempjes waarna de plant afsterft. De plant produceert dan wel veel zaad en zo kan men de plant gemakkelijk zaaien.
  • Verlangt een humusrijke, goed doorlaatbare grond op een beschutte warme locatie.
  • Winterhard tot -5°C maar heeft een hekel aan natte winters.
  • Best is om de plant toch vorstvrij te laten overwinteren.
Melanoselinum decipiens (Madeira Giant Black Parsley)
Madeira Giant Black Parsley makes an impressively tall, single woody stem crowned by a broad rosette of huge, glossy, deeply cut leaves and a very broad umbel with rosy-white flowers on maturity, after which the plant will die down, leaving numerous seeds. From open spots in the laurel forest and humid places in mountains of central Madeira (Portugal). Form 1 has large seeds and occurs at lower altitudes and is found cultivated as an ornamental foliage plant in gardens in the North of Madeira, whereas form 2 has smaller seeds and derives from high elevations. For any humus rich, well drained soil in a partially shaded (summer) to sunny (winter) spot. In winter keep plants slightly drier at a minimum of some 10°C. An exceptional, extremely beautiful foliage plant, which is impressive not only for its size!

Phytochemical Profile, Chemotaxonomic Studies, and In Vitro Antioxidant Activities of Two Endemisms from Madeira Archipelago: Melanoselinum decipiens and Monizia edulis (Apiaceae). Spínola V1, Castilho PC2.
Melanoselinum decipiens and Monizia edulis (Apiaceae) are two endemic plants from Madeira archipelago, phytochemical compositions of which remains little explored, despite their use in folk medicine. Using liquid chromatography with diode array and electrospray ionization/mass spectrometry analysis, their polyphenolic profile was established for the first time. Fifty-six compounds were identified with 5-O-caffeoylquinic acid, quercetin-O-(malonyl)hexoside, luteolin diacetyl, and quercetin-O-hexoside being the major constituents in the leaves of both plant species (≥ 0.76 mg/g of dry extract). Principal component analysis provided a suitable tool to differentiate targeted plants. Naringenin-6,8-di-C-glucoside, quercetin 3-O-pentosylhexoside, and 1,5-O-dicaffeoylquinic acid can be used as discriminatory taxonomic/geographical markers for M. edulis subspecies from Madeira and Porto Santo populations. This methodology of using polyphenols as chemotaxonomic markers proved to be useful for identification of plant species since the results are consistent with previous taxonomical data. The free-radical scavenging activities of the M. decipiens extracts proved to be higher than those of M. edulis, which correlated well with their phenolic content (R2  > 0.906).
