可以大晚上喝的奶茶要來啦

Hongyacha, a new type of wild tea plant from themountains of southern China, contains little or nocaffeine, according to a study published in theJournal of Agricultural and Food Chemistry.

根據(jù)一篇發(fā)布在《農(nóng)業(yè)與食品化學(xué)期刊》上的研究，一種在中國南方山區(qū)發(fā)現(xiàn)的新品種野生茶，只含很少的咖啡因，有的甚至不含;這種茶被稱為洪崖茶。

“Hongyacha is a wild tea plant only distributed in thenarrow mountain area at altitudes of 2,300-3,300 feet (700-1,000 m) of several neighboring villages inthe southern region of Fujian Province,” said leadauthor Dr. Liang Chen from China’s Tea Research Institute and colleagues.

該論文的主要作者是來自中國茶葉研究所的Liang Chen博士，Chen博士及其同事說：“洪崖茶這種野生茶樹只在福建省南方山區(qū)很窄的一個(gè)村落帶附近生長，海拔700-1000米。”

“Local people believe that drinking this tea can reduce internal heat, cure colds, and healstomach pains, etc.”

“當(dāng)?shù)厝讼嘈藕冗@種茶能夠去內(nèi)熱、治療感冒、治胃痛等等。”

“However, given its narrow and special distribution, detailed information about hongyacha islacking.”

“不過，受限于它狹窄且特殊的生長區(qū)域，現(xiàn)在有關(guān)洪崖茶的詳細(xì)信息還比較少。”

 

 

In the new study, Dr. Chen and co-authors characterized the chemical components ofhongyacha by using high-performance liquid chromatography.

在新的研究中，Chen博士與其他幾位聯(lián)合作者運(yùn)用高性能的色譜分析法確定了洪崖茶的化學(xué)成分。

They found that buds and leaves of hongyacha contain several potentially health-promotingcompounds and virtually no caffeine.

Digging deeper, the team found that hongyacha has a mutation in the gene encoding theenzyme tea caffeine synthase, which promotes caffeine production in most tea plants.

在更深入的研究之后，團(tuán)隊(duì)發(fā)現(xiàn)洪崖茶的一個(gè)基因發(fā)生了變異，這個(gè)基因正是編碼茶葉咖啡因合成酶的基因，在大部分茶種種這個(gè)基因都會促進(jìn)茶樹分泌咖啡因。

“Naturally low-caffeine hongyacha could possibly become a popular drink because of itsdistinct composition and unique health benefits,” the scientists said.

這些科學(xué)家們說：“考慮到它獨(dú)特的成分和保健功效，洪崖茶這種天然的低咖啡因茶或許能成為一種流行的飲品。”
