“…Studies have shown that pine needle oil has anti-inflammatory and antiblastic effects and can significantly inhibit . biosynthesis (Pichette et al, 2006;Jeong et al, 2007). In another study, a pine needle extract solution was found to inhibit the rate of growth of a mouse transplantable tumor by more than 40% (Loizzo et al, 2010).…”

Background: Pine needle oil from crude extract of pine needles has anti-tumor effects, but the effective component is not known. Methods: In the present study, compounds from a steam distillation extract of pine needles were isolated and characterized. Alpha-pinene was identified as an active anti-proliferative compound on hepatoma carcinoma BEL-7402 cells using the MTT assay. Results: Further experiments showed that α-pinene inhibited BEL-7402 cells by arresting cell growth in the G2/M phase of the cell cycle, downregulating Cdc25C mRNA and protein expression, and reducing cycle dependence on kinase 1(CDK1) activity. Conclusion: Taken together, these findings indicate that α-pinene may be useful as a potential anti-tumor drug.

“…Although, several researchers have reported the efficiency of plant extracts to suppress 28°C (day) and 22°C (night) and 16 h light: 8 h dark photoperiod. The highly infected leaves were gently scraped to collect conidia and washed with sterile distillated water (SDW), then the spores were suspended in tubes and filtrated through sterilized cheese cloth ( Jeong et al, 2007). The spore suspensions were determined by a hemocytometer and adjusted to concentration 1 × 10 5 conidia ml -1 for inoculating plants.…”

The preventative and curative effects of some plant derived agents based on plant extracts or essential oils were studied at different concentrations against Erysiphe cichoracearum DC. ex Merat, the causal pathogen of okra powdery mildew by the detached leaf-disk and potted plants bioassays. Through detached leaf-disk assay, the highest mean preventative effect (97.74%) was recorded by neem seed oil followed by jojoba oil (89.82%) and extract of Rynoutria sachalinensis (82.77%). Neem seed oil at 1% was the most effective agent followed by jojoba oil and extract of R. sachalinensis at 1.5% and 2%, respectively, where they suppressed E. cichoracearum completely. Potted plants assay revealed that neem seed oil, jojoba oil and extract of R. sachalinensis as well as the fungicide (active ingredient dinocap) showed higher preventative efficacy at all leaf olds treated after 7 and 14 days of inoculation as compared with extracts of henna and garlic. Moreover, the preventative efficacy partly remained apparent after 14 days of inoculation at all leaf olds tested. In field trials through 2010 and 2011 growing seasons, when the first symptoms of powdery mildew appeared naturally, 1.5% jojoba oil, 2% extract of R. sachalinensis and 1% neem seed oil were sprayed individually twice on grown plants to evaluate their efficacy on controlling powdery mildew, growth and yield of okra. Resulted showed that neem seed oil was the most effective agent and highly decreased the disease severity to 29.92%, recorded the highly curative effect (68.15%) and also improved plant growth and pods yield.

“…In the previous reports, the yields of essential oils from the needles, twigs and cones, as well as twigs with needles of A. koreana (by after 5 h of hydrodistillation) were 1.0%, 0.64%, 0.42% and 0.83%, respectively [9]. In other studies, 0.6%, 0.53%, and 0.9% of essential oil yields were obtained from the needles of A. koreana by Lee and Hong [2], Oh et al [3] and Jeong et al [10] respectively. In the present study, it was observed that the harvesting times highly influenced on the essential oil yield with the highest value in August (1.20%) and the lowest value in April (0.76%).…”

“…In addition, the supercritical carbon dioxide extract from the needles of A. koreana exhibited memory enhancing effect in mice [8]. Previously, some authors reported the essential oil composition and its antimicrobial activity of A. koreana of different origins [2,3,9,10]. However, the published data about the essential oil composition of A. koreana has been extensively varied between the authors.…”

Objective: In the present study, the influence of harvesting time (April, June, August and October 2015) on the essential oil composition of Abies koreana twigs from Korea was investigated. Methods:The essential oil from the twigs of A. koreana was isolated by steam distillation and its chemical composition was determined by gas chromatography-mass spectrometry (GC-MS). Results:The essential oil yield was found to vary from 0.76 to 1.20% depending on the month of harvesting. The GC-MS analysis revealed the identification of 26 different essential oil components from the twigs harvested in the months of April, June, August and October, which were mostly monoterpene hydrocarbons (57.63-72.38%) followed by oxygenated monoterpenes (18.82-25.96%). Harvesting time mainly influenced on the concentration of the major components of the essential oil from the twigs of A. koreana. Limonene (17.38-31.13%), bornyl acetate (13.22-21.17%), camphene (12.56-13.26%), α-pinene (11.05-13.02%), β-pinene (4.55-5.70%), 3-carene (5.21-6.43%) and β-eudesmol (1.49-8.24%) were detected as the major components in the essential oil. Conclusion:The main differences between the essential oil compositions of four different months can be referred to limonene and bornyl acetate. The results showed considerable variations in the composition of essential oil, particularly quantitative variation during different harvesting months.
