The soil and climatic conditions are conducive for the growth of a lot of medical herbs in Kosovo. Lipids, proteins, minerals and essential
oils were quantitatively determined from the Pinus nigra Arnold and Pinus sylvestris growing wild in Germia Park (located in the northeast of Pristina). Total proteins were analyzed, by Kjeldahl method. The total amount of proteins in Pinus nigra Arnold is 7.714 % and in
Pinus sylvestris is 4.375 %. Lipids are analyzed by Soxhlet extraction. The total amount of lipids in Pinus nigra Arnold are 7.185 % and in
Pinus sylvestris 6.670 %. Essential oils were isolated using steam distillation. The total amount of essential oils in Pinus nigra Arnold are
0.35 % and in Pinus sylvestris 0.32 %. The mineral content was studied and analyzed by flame atomic absorption spectrometry. Six
elements, sodium, potassium, calcium, zinc, iron and copper were determined in Pinus nigra Arnold and Pinus sylvestris. The mean levels
of sodium, potassium, calcium, zinc, iron and copper are 246 mg kg-1
, 1280 mg kg-1
, 4260 mg kg-1
, 17.2 mg kg-1
, 173 mg kg-1
, 3.83 mg kg-1
in Pinus nigra Arnold, respectively. The mean levels of sodium, potassium, calcium, zinc, iron and copper are 6.9 mg kg-1
, 420 mg kg-1
,
1180 mg kg-1
, 95 mg kg-1
, 840 mg kg-1
, 19 mg kg-1
in Pinus sylvestris, respectively. Calcium and potassium are present in large amounts in
Pinus nigra Arnold while calcium and iron are present in large amounts in Pinus sylvestris.
