Faaali atili
1. Yu Honghong, Gao Xiaoyan. Faʻavae i luga o le UPLC-Q-TOF / MS ~ E, suʻesuʻega vave o vailaʻau faʻapitoa i mianyinchen [J]. Sen…

 

Vaaiga lautele p-hydroxyacetophenone, ona o lona mole o loʻo i ai vaega o le hydroxyl ma le ketone i luga o le mama benzene, o le mea lea, e masani ona faʻaaogaina e avea o se vaeluaga i le faʻaogaina o meaola e tali atu ai ma isi mea faʻapipiʻi e faʻapipiʻi le tele o mea taua. E masani ona faʻaaogaina mo le tuʻufaʻatasia o vailaʻau faʻapitoa (α-bromo-p-hydroxyacetophenone, vailaʻau choleretic, analgesics antipyretic ma isi vailaʻau), Isi (mea manogi, fafaga, ma isi; Pesticides, vali, mea tioata vai, ma isi).
Fa'atatauga p-hydroxyacetophenone o se nila paʻepaʻe tioata i le vevela o le potu, e masani ona tupu i aʻa ma lau o Artemisia scoparia, i aʻa o laau e pei o le ginseng pepe Vine. E mafai ona faʻaaogaina i le gaosiga o vailaʻau choleretic ma isi mea mata mo le faʻaogaina o meaola.
