      According to the analysis of Yunnan Province Tea Research Institute of biochemistry research, by Zijuan tea varieties of tea one bud two leaves of steamed green tea polyphenol content was 35.52% and amino acid 3.49%, the water extract 44.585; summer red black tea theaflavins content was 0.91%, tea and red 6.99%, theabrownin 5.86% and sense of officer identified strong intensity score was 34.7, refreshing degree score 37.6.

      Zijuan "dried bean curd Tan Ze purple black, tea is pale purple, mellow aroma, Sauvignon back to Gan, and has certain health care function. In 1991, Yunnan pharmaceutical research used "Zijuan" tea buck animal experiments. The results show that "Zijuan" tea depressurization amplitude (35.53%) was better than that of Yunnan big leaf groups for green tea (29.04%). Other after more than hypertension patients taking "Zijuan" tea, reflect the good curative effect that "Zijuan" tea has some medicinal value.
      From 1999 to 2000, province tea Institute of scientific and technical personnel carried out "special purple tea (tea Zijuan) natural antihypertensive substance of (Ministry of Agriculture Tea biotechnology Key Laboratory fund project), the results showed that the" Zijuan "tea flavonoids, caffeine, zinc, anthocyanins and other substances in large leaf tea is high than in the control. According to the study, "Zijuan" tea with high content of flavonoids, zinc and supernormal anthocyanins are present significantly lower blood pressure of the main material.
      "Zijuan" has the characteristics of cold resistance, drought resistance, disease and insect resistance ability, cutting propagation and transplant survival rate is high, suitable for in the warm, moist and plenty of sunshine, fertile soil (pH 4.5 - 5.5) of the ecological environment in growth, at an altitude of 800 - 2000 meter Yunnan main tea producing area planting, has been popularized in Xishuangbanna, Puer, Lincang, Baoshan District tea planted 3000 acres. In 2005, "Zijuan tea" by the State Forestry Administration of the right to the protection of new varieties of plants.
      Zijuan, with an average altitude of 2600 meters, year-round wind around the clouds, temperature difference between day and night 15 DEG C, the original ecological preservation best place - Yunnan Province wa mountain. Yunnan Dayezhong is a rare and unique varieties, and for more than 100 years of tree natural variation. Because rare highlights precious. This product selects the purple tea pure material, the traditional handicraft production. Pie full of atmosphere, of the cable tight node handsome, dry tea color glossy black oil lubrication; liquor color bright, aroma fragrance, full taste, taste moist cotton slip, Qingxin Runfei, quite and beautiful trait. Cup of fragrant lasting, durable foam, thick soft soft. Dr. Wang Meijin after drinking tea sigh said "the white boiling water is Zijuan, drink sweet".

      Antihypertensive effect
In 1991 by the Yunnan Institute of Pharmaceutical Research Institute senior engineer Lin Yongyue, who used the weight of 2.5 ~ 3.5kg
Zijuan tea bud germination period in late February, late March to early April for a clover bud stage. Bud strong, germination medium density, leaf bud purple, a fat, hair, tenderness strong. One bud and one hundred bud weight is 115g. Cuttage is progenitive ability, high survival rate, cold resistance, drought resistance, disease and insect resistance strong, large leaved species planted in suitable, cultivation methods with Yunnan Dayezhong. The varieties of tea in moderate yield. According to Yunnan Province tea of the test, the experiment 6 ~ 10 underage tea average per mu yield of dry tea 103.3kg.
According to the analysis of Yunnan Province Tea Research Institute of Biochemistry, by Zijuan tea varieties of tea one bud two leaves the cat was repeatedly hypotensive experiment, the results show that, Zijuan green tea, depressurization amplitude is 35.53% than Yunnan large leafed tea (29.04%). At present, Yunnan Province Tea Research Institute developed based on Zijuan antihypertensive health tea, is increasing Zijuan tea varieties breeding, and expect to take advantage of the development, in losing weight, lowering blood sugar and so on.
