The volatile oil content and composition of the aerial parts of Ajuga orientalis L. (Lamiaceae) grown in northern parts of Iran have been analyzed by GC/MS. Thirty compounds were identified, representing 97.9% of the total oil. The main compounds were germacrene-D (24.2%), β-cubebene (18.3%), β-caryophyllene (16.9%) and α-cubebene (5.3%).

Abstract. Sandalwood is source of essential oil and as non-wood commodity of forest, which is potential and considered luxurious due to its distinctiveness hard wood and containing specific oil scent. Sandalwood oil can be produced from its wood by extracting from its tree trunks, twigs, brances, or root. The economic value of sandalwood plan is derived from its oil content (santalol) which has unique scent. A volatile oil contained in sandalwood is the sesquiterpenoid compound; among them are α-santalol dan b-santalol. Interaction between genetic factors of plant with its environment is a major factor that determines the growth and development of sandalwood plant that eventually affecting the volatile oil that can be produced. Engineering efforts are required against factors that  related with oil extraction in order to obtain its maximum production in both in quantity and quality. Sandalwood oil has high functional value, some of them are as the material for aromatic therapy which is particularly beneficial for human health, as cosmetic material, and as material for medicines.Keywords : sandalwood, essential oil, santalol Sari. Cendana merupakan sumber penghasil minyak atsiri dan merupakan komoditi hasil hutan bukan kayu yang potensial dan tergolong mewah karena sifat kayu terasnya yang khas dan mengandung minyak dengan aroma yang spesifik. Pembuatan minyak cendana dapat dilakukan dengan memanfaatkan batang kayu, ranting, cabang ranting, dan akar pohon cendana. Nilai ekonomi tanaman cendana didapat dari kandungan minyak (santalol) dalam kayu yang beraroma wangi yang khas. Minyak atsiri yang terkandung pada kayu cendana merupakan golongan senyawa sesquiterpenoid diantaranya α-santalol dan b-santalol. Interaksi antara faktor genetik tanaman dengan ling-kungan merupakan faktor utama yang menentukan pertumbuhan dan perkembangan tanaman cendana yang pada akhirnya berpengaruh terhadap produksi minyak atsiri yang dihasilkan. Diperlukan upaya rekayasa terhadap faktor-faktor yang terkait dengan ektraksi minyak cendana sehingga produksi maksimal dicapai baik secara kuantitas maupun kualitas. Minyak cendana memiliki nilai fungsi yang tinggi diantaranya sebagai bahan aroma terapi yang sangat bermanfaat bagi kesehatan manusia, bahan kosmetik, dan bahan untuk obat-obatan.Kata kunci : tanaman cendana, minyak atsiri, santalol

Boronia heterophylla is cultivated for cut flowers and B. megastigma for volatile oil production. Both species are endemic to south-western Western Australia and their natural habitat is often shaded by a canopy of Melaleuca parviflora or Eucalyptus marginata. Shade tents were used to examine the influence of reduced photon flux density (PFD) on photosynthesis, growth, and flower production in B. heterophylla and B. megastigma. Volatile oil content was also examined in B. megastigma. Photosynthesis in field-grown B. heterophylla was saturated at 16·2 µmol CO2/m 2·s under a PFD of 1022 µmol/m 2·s (75% full sunlight). Flower number was highest under 75% full sunlight but the number of harvestable stems was the same under 75% and full sunlight. More flowers were produced by B. megastigma plants grown under 75% full sunlight. Content of α-pinene and limonene decreased with decreasing light intensity, whereas β-ionone and docecyl acetate increased with decreasing light intensity

A survey has been made of the variations and of some of the factors influencing the variations of the vitamins A and D potencies of the liver oil of cod landed at ports in Nova Scotia, New Brunswick, and the Gaspé peninsula of Quebec. An increase in the vitamin A potency was paralleled by an increase in the vitamin D potency and the oil content of the liver increased with the percentage liver in the fish. An increase in the oil content of the liver and of the liver content of the fish was accompanied by a decrease in the concentration of vitamins A and D in the oil. The vitamin potency of the oil tended to decrease as the fishing season advanced from June to October and the oil content of the liver increased during this period. When the yield of vitamins was expressed per 100 gm. of fish there was no apparent seasonal change in potency indicating that the seasonal changes observed were due to dilution. A relationship was observed between the stages in the spawning cycle and the oil content of the liver. Fish classed as "steaks" (six to eight years) yielded a liver oil higher in vitamins A and D potencies than "market cod" (four to six years) and the liver oil of "scrod" (three to four years) had the lowest vitamins A and D potencies.
