(1S)-(-)-α-Pinene CAS 7785-26-4 yog alpha-pinene. Nws yog ib qho enantiomer ntawm (+)-alpha-pinene. Pinene (C10H16) yog ib qho bicyclic monoterpene tshuaj compound. Muaj ob lub isomers ntawm pinene pom nyob rau hauv xwm: α-pinene thiab β-pinene. Raws li lub npe qhia, ob daim ntawv yog cov khoom tseem ceeb ntawm cov ntoo thuv resin; lawv kuj pom muaj nyob rau hauv cov resins ntawm ntau lwm yam conifers, nrog rau hauv cov nroj tsuag uas tsis yog coniferous xws li camphorweed (Heterotheca) thiab big sagebrush (Artemisia tridentata). Ob qho tib si isomers yog siv los ntawm ntau kab hauv lawv cov tshuaj sib txuas lus. Ob lub isomers ntawm pinene tsim cov khoom tseem ceeb ntawm turpentine.
Alpha pinene yog ib qho khoom siv tseem ceeb rau kev tsim cov aromatics, feem ntau yog siv rau hauv kev tsim cov pinol, linalool thiab qee cov txuj lom sandalwood. Kuj tseem siv tau rau cov khoom siv tshuaj txhua hnub thiab lwm yam khoom lag luam los ntxiv cov tshuaj tsw qab. Nws tseem yog cov khoom siv raw ntawm cov roj nplua nyeem hluavtaws, plasticizer, terpene resin thiab lwm yam.
1. Cov nyhuv tiv thaiv kab mob qog nqaij hlav
2. Cov nyhuv tiv thaiv kab mob fungal
3. Tiv thaiv kev ua xua thiab kev txhim kho ntawm qhov txhab
Hauv kev tshawb fawb txog kev txhim kho cov qhov txhab, Pinheiro Mde A et al. tau rho tawm -pinene los ntawm cov roj tib neeg los kho cov qhov txhab hauv plab hauv nas, thiab pom tias -pinene muaj cov haujlwm tiv thaiv kev mob txhab.
Alpha Pinene (α-Pinene) yog cov khoom siv pib rau kev tsim cov terpineol, camphor, borneol thiab terpene resin, cov tshuaj tsw qab thiab cov resins, tshuaj thiab lwm yam tshuaj lom neeg organic.
