Ngā Theaflavin (TF)meNgā Thearubigins (TRs)E rua ngā rōpū motuhake o ngā matū polyphenolic e kitea ana i roto i te tī pango, he ahurei ngā hanganga matū me ngā āhuatanga o ia rōpū. He mea nui te mārama ki ngā rerekētanga i waenga i ēnei matū kia mārama ai ki ā rātou takoha takitahi ki ngā āhuatanga me ngā painga hauora o te tī pango. Ko te whāinga o tēnei tuhinga he whakarato i tētahi tūhuratanga whānui o ngā rerekētanga i waenga i ngā Theaflavin me ngā Thearubigins, me te tautokona e ngā taunakitanga mai i ngā rangahau e tika ana.
He flavonoid ngā theaflavin me ngā thearubigins, ā, ka whai wāhi rāua ki te tae, te reka, me te tinana o te tī.He karaka, he whero rānei ngā theaflavin, ā, he whero-parauri ngā thearubigins.Ko ngā theaflavin ngā flavonoid tuatahi ka puta i te wā o te waikura, ko ngā thearubigins ia ka puta i muri mai. Ka whai wāhi ngā theaflavin ki te kawa, te kanapa, me te koi o te tī, ko ngā thearubigins ia ka whai wāhi ki tōna kaha me te reka o te waha.
Ko ngā theaflavin he momo matū polyphenolic e whai wāhi ana ki te tae, te reka, me ngā āhuatanga whakatairanga hauora o te tī pango. Ka hangaia ēnei mā te whakapūtanga waikura o ngā catechin i te wā o te tukanga whakapūtanga o ngā rau tī. E mōhiotia ana ngā theaflavin mō ō rātou pānga antioxidant me te anti-inflammatory, kua honoa ki ngā painga hauora maha, tae atu ki te tiaki i te pūnaha cardiovascular, ngā āhuatanga anti-cancer, me ngā pānga anti-chrombosis pea.
I tētahi atu taha,Ngā TiārubiginsHe pūhui polyphenolic nui ngā mea nei, ā, i ahu mai anō hoki i te waikura o ngā polyphenols tī i te wā e whakapūpūtia ana ngā rau tī. Ko rātou te take o te tae whero momona me te reka motuhake o te tī pango. Kua honoa ngā thearubigins ki ngā āhuatanga antioxidant, anti-inflammatory, me te tiaki kiri, ā, he mea nui ki te ao o te anti-aging me te tiaki kiri.
I runga i te hanganga matū, he rerekē ngā Theaflavin i ngā Thearubigins i runga i te hanganga ngota me te hanganga. He pūhui dimeric ngā Theaflavin, arā, mā te whakakotahitanga o ngā waeine iti e rua ka hangaia, ko ngā Thearubigins ia he pūhui polymeric nui ake i puta mai i te polymerization o ngā flavonoids i te wā o te whakapūkara tī. Ka whai wāhi tēnei rerekētanga hanganga ki ō rātou mahi koiora rerekē me ngā pānga hauora pea.
| Ngā Theaflavin | Ngā Tiārubigins | |
| Tae | Karaka, whero rānei | Whero-parauri |
| Te takoha ki te tī | Te kanapa, te pakari, me te kaha | Te kaha me te reka o te waha |
| Hanganga matū | Kua tautuhia pai | He rerekē, kāore i te mōhiotia |
| Ōrau o te taumaha maroke i roto i te tī pango | 1–6% | 10–20% |
Ko ngā theaflavin te rōpū matua o ngā matū e whakamahia ana hei aromatawai i te kounga o te tī pango. Ko te ōwehenga o ngā theaflavin ki ngā thearubigins (TF:TR) me 1:10 ki te 1:12 mō te tī pango kounga teitei. Ko te wā whakapūkara he mea nui hei pupuri i te ōwehenga TF:TR.
Ko ngā theaflavin me ngā thearubigins he hua motuhake i hangaia mai i ngā catechin i te wā e whakapūngaohia ana te tī i te wā e hangaia ana. Ka hoatu e ngā theaflavin he tae karaka, karaka-whero rānei ki te tī, ā, ka whai wāhi ki te ahua o te waha me te whānuitanga o te hanganga kirīmi. He pūhui dimeric ēnei he angaanga benzotropolone i hangaia mai i te whakapūngao tahi o ngā takirua catechin kua tohua. Ko te whakapūngao o te mowhiti B o te (−)-epigallocatechin, o te (−)-epigallocatechin gallate rānei ka whai i te ngaronga o te CO2 me te hanumitanga i te wā kotahi me te mowhiti B o te ngota (−)-epicatechin, o te (−)-epicatechin gallate rānei (Pikitia 12.2). E whā ngā theaflavin matua kua tautuhia i roto i te tī pango: te theaflavin, te theaflavin-3-monogallate, te theaflavin-3′-monogallate, me te theaflavin-3,3′-digallate. Hei tāpiri, ka kitea pea ō rātou stereoisomers me ngā derivatives. Nō nā tata nei, i puta ngā pūrongo mō te aroaro o te theaflavin trigallate me te tetragallate i roto i te tī pango (Chen et al., 2012). Ka taea te whakahāngai anō i ngā theaflavin. Koinei pea ngā matūtake mō te hanganga o ngā thearubigins polymeric. Heoi, kāore anō kia mōhiotia te tikanga o te tauhohenga. Ko ngā thearubigins he tae whero-parauri, parauri pouri rānei i roto i te tī pango, ā, tae atu ki te 60% o te taumaha maroke o te tī e ringihia ana ki roto i ēnei tae.
Mō ngā painga hauora, kua rangahauhia whānuitia ngā Theaflavin mō tā rātou mahi pea ki te whakatairanga i te hauora o te ngākau me te ngākau. Kua whakaatuhia e ngā rangahau ka āwhina pea ngā Theaflavin ki te whakaiti i ngā taumata cholesterol, ki te whakapai ake i te mahi a ngā oko toto, me te whakaatu i ngā pānga ārai-mumura, ā, he pai katoa ēnei mō te hauora o te ngākau me te ngākau. Hei tāpiri, kua whakaatuhia e ngā Theaflavin te kaha ki te aukati i te tipu o ngā pūtau matepukupuku, ā, tera pea he āhuatanga ārai-mate huka.
I tētahi atu taha, kua honoa ngā Thearubigins ki ngā pānga antioxidant me te anti-inflammatory, he mea nui mō te whawhai ki te ahotea oxidative me te mumura i roto i te tinana. Tērā pea ka whai wāhi ēnei āhuatanga ki ngā pānga anti-chronicity me te tiaki kiri o ngā Thearubigins, ka waiho hei kaupapa e hiahiatia ana i roto i ngā rangahau tiaki kiri me ngā rangahau e pā ana ki te koroheketanga.
Hei whakamutunga, he rerekē ngā Theaflavin me ngā Thearubigins i roto i te tī pango, he rerekē ngā hanganga matū me ngā painga hauora o ia tī. Ahakoa kua honoa ngā Theaflavins ki te hauora o te pūnaha manawa, ngā āhuatanga ārai-matepukupuku, me ngā pānga ārai-mate huka pea, kua honoa ngā Thearubigins ki ngā āhuatanga antioxidant, anti-inflammatory, me te tiaki kiri, ā, he kaupapa tēnei e hiahiatia ana i roto i ngā rangahau ārai-pakeketanga me te tiaki kiri.
