Mawu Oyamba

α-Angelica lactone ndi organic pawiri ndi mankhwala dzina (Z) -3-butenoic acid-4-(2'-hydroxy-3'-methylbutenyl) -ester. Zotsatirazi ndizofotokozera za katundu, ntchito, njira zokonzekera ndi chidziwitso cha chitetezo cha α-Angelica lactone:

Ubwino:

- Maonekedwe: Makristalo oyera olimba

- Kusungunuka: Kusungunuka pang'ono m'madzi, kusungunuka mu zosungunulira organic monga ethanol ndi chloroform

Gwiritsani ntchito:

- Chemical kaphatikizidwe: α-Angelica lactone Angagwiritsidwenso ntchito m'munda wa kaphatikizidwe organic monga zofotokozera kapena wapakatikati.

Njira:

Pakalipano, njira yokonzekera α-angelica lactone imapezeka makamaka ndi kaphatikizidwe ka mankhwala. Njira yophatikizira yomwe imagwiritsidwa ntchito kwambiri ndikupanga α-angelica lactones pochita mamolekyu a cyclopentadienic acid okhala ndi mamolekyu a 3-methyl-2-buten-1-ol pansi pamikhalidwe yoyenera.

Zambiri Zachitetezo:

- α-Angelica lactone ndi yotetezeka kuti igwiritsidwe ntchito nthawi zonse, komabe ndikofunikira kutsatira njira zodzitetezera za labotale.

- Pewani kukhudza khungu mwachindunji ndikutsuka ndi madzi ambiri ngati pakhudzana.

- Samalani kupewa moto ndi kutentha kwambiri panthawi yosungira ndikugwira.

- Munthu akakoka mpweya mwangozi kapena mwangozi, pitani kuchipatala mwamsanga.
