Hoʻolauna

ʻO ka Ligustral (ʻike ʻia ʻo xanthrin) he pūhui mea ola. ʻO kēia ka hoʻolauna ʻana i nā waiwai, hoʻohana, nā ʻano hoʻomākaukau a me ka ʻike palekana o ka ligustral:

 

ʻAno maikaʻi:

- He paʻa kala ʻole ʻo Ligustrum a hiki i ka melemele me ka ʻala ʻala ikaika ma ka lumi wela.

- Hiki ke hoʻoheheʻe ʻia i loko o nā mea hoʻoheheʻe kūlohelohe e like me ka ethanol, ethers a me nā mea hoʻoheheʻe ester ma ka lumi wela, akā aneane hiki ʻole ke hoʻoheheʻe ʻia i ka wai.

- Loaʻa i ka Ligustral ka volatility kiʻekiʻe a maʻalahi ka sublimate.

 

E hoʻohana:

- Hoʻohana nui ʻia ia i ka ʻoihana ʻono ma ke ʻano he mea kanu mea kanu kūlohelohe hiki ke hāʻawi i nā waiwai ʻala i nā huahana.

 

Hanana:

- Hiki ke hoʻomākaukau ʻia ka ligustrum ma o ka hoʻonā ʻana o ka ligustrum (i loaʻa mai ka hua ligustrum). Loaʻa ka Ligustrum ma ka hana ʻana ma lalo o nā kūlana kūpono me kahi mea hoʻokahe e like me ka acidic potassium permanganate a i ʻole oxygen.

 

ʻIke palekana:

- Manaʻo ʻia ʻo Ligustaldehyde he pūhui palekana, akā pono ia e mālama pono.

- He mea hoʻonāukiuki e hoʻonāukiuki i ka maka, ka ʻili, a me ka ʻōnaehana hanu.

- Pono e pale aku i ka ligustrum i ka wā o ka hana a pono e hōʻoia i ka ea maikaʻi.

- I ka lawelawe ʻana i ka ligustrum, e hoʻokomo i nā lako pale pilikino e like me nā mīkina lima, nā aniani pale, a me nā maka.
