한국 자생 차나무의 채취 다엽에서 차의 품질관련 주요 화학성분을 분석한 결과는 다음과 같다. 1. 전질소 함량은 3.59~4.89%% 사이로 보성 대원사, 화순 쌍봉사, 순천 창천리, 하동 쌍계사, 강진 장원산업 다엽에서 함량이 많았다. 2. 다엽의 유기성분 함량중 tannin은 12.5%~18.3% 범위였으며, 영광 천마리, 함평 용암리, 여수 우두리 다엽이 12.5%, 12.7%, 12.8%로 함량이 적고, 구례 천은사, 강진 백련사, 나무 불회사 다엽이 18.3%, 16.7%, 16.4%로 함량이 많았다. 3. Caffeine은 2.21~3.11% 범위로 담양 양각리, 여수 우두리, 구례 화엄사 다엽이 2.21%, 2.23%, 2.23%로 적고, 광주삼애다원, 강진 장원산업, 순천 창천리다엽이 3.11%, 2.94%, 2.87%로 함량이 많았다. 4. Vit. C는 167.9g~223.5mg/100g 범위로 장성 오산리, 순천 송광사, 영광 천마리 다엽이 167.9mg/100g, 185.6mg/100g, 185.8mg/100g로 적고 광주 삼애다원, 강진 장원산업, 순천 창천리 다엽이 291.5mg/100g, 271.8mg/100g, 269.5mg/100g으로 함량이 많았다. 5. 엽록소는 187.4~332.7mg/100g 범위로, 평균 함량은 242.0mg/100g 이었다. 6. 아미노산은 1,888~2,500mg/100g으로 강진 장원산업이 2,500mg/100g으로 함량이 가장 높고, 순천 송광사가 1,888mg/100g으로 가장 낮았다. 7. 보성 대원사, 화순 쌍봉사, 순천 창천리, 하동 쌍계사, 강진 장원산업 채취 다엽이 전질소와 아미노산 함량이 많고, 탄닌 함량이 적어 품질이 양호하리라 생각된다.
The significant chemical components estimating the quality of green tea were compared and analyzed in the shoots of Korean native tea plants. The results are summarized as follows. The contents of total nitrogen in tea leaves were in range of 3.59~4.89%, and the tea plants grown wildly in Bosong Daewonsa, Hwasun Ssangbongsa, Shunchun Changchun-ri, Hadong Ssanggyesa. and the cultivated tea plants in Kangjin Jangwon Sanup had higher contents of total nitrogen. The contents of tannin ranged from 12.5 to 18.3%. The contents of tannin of Kuryoi Chonunsa (18.3%), Kangjin Baekryonsa (16.7%) and Naju Bulhoisa (16.4%) were higher than those of Yangkwang Chonma-ri (12.5%), Hampyong Yongam-ri (12.7%) and Yosu Udu-ri (12.8%). The contents of caffeine were in range of 2.21~3.11%. The contents of caffeine of Kwangju Shamae Dawon (3.11%), Kangjin Jangwon Sanup (2.94%) and Shunchun Changchun-ri(2.87%) were higher than those of Tamyang Yanggak-ri(2.21%), Yosu Udu-ri(2.23%) and Kuryoi Hwaomsa (2.23%). The contents of vit. C were in range of 167.9~223.5mg/100g. The contents of vit. C of Changsong Oshan-ri (167.9mg/100g), Shunchun Shongkwangsa (185.6mg/100g) and Yongkwang Chonma-ri (185.8mg/100g) were lower than those of Kwangju Shamae Dawon (291.5mg/100g), Kangjin Jangwon Sanup (271.8mg/100g) and Shunchun Changchun-ri (269.5mg/100g). The contents of chlorophyll were in range of 187.4~332.7mg/100g, and the mean contents were in range of 242.0mg/100g. The contents of total amino acids were in range of 1,888~2,500mg/100g. The content of total amino acid at Kangjin Jangwon Sanup was the highest as 2,500mg/100g, and that of Shunchon Shongkwangsa was the lowest as 1,888mg/100g. Results of this study suggest that the native tea plants naturally grown at Bosong Daewonsa, Hwasun Ssangbongsa, Shunchun Changchun-ri, Hadong Ssanggyesa, and the cultivated tea plants at Kangjin Jangwon Sanup show excellent quality in terms of abundance of total nitrogen and total amino acids, and less contents of tannin.
