我国22种野生蔷薇果实主要经济性状及重要维生素含量

分析了中国蔷薇属植物２２个野生种果实的鲜重、含水量、可食部等经济学性状，并测定了ＶＣ、ＶＥ和胡萝卜素等重要维生素的含量，ＶＣ含量以腺齿蔷（３２４０ｍｇ／１００ｇ鲜果肉）和弯刺蔷薇（３１５９ｍｇ／１００ｇ）为最高，川滇蔷薇（５１ｍｇ／１００ｇ）和绢毛蔷薇（６３ｍｇ／１００ｇ）的含量最低。蔷薇果的ＶＣ含量还与组的划分有一定的相关性，例如，桂味组的种类含量一般在１０００ｍｇ／１００ｇ以上；合柱组含量相对

Determination of Major Economic Characters and Vitamins in the Fruits of 22 Species of Rosa from China

Here is the report of the study on vitamin C, E, carotenes and some major economic characters in fruits of 22 Rosa species from China. The variation of vitamin C contents ranged within 50~3200mg/100g (fresh pulp). The highest VC contents were shown by R. albertii (3240mg/100g) and R. beggeriana (3159mg/100g),the lowest by R. soulieana (51mg/100g) and R. sericea (63mg/100g). The relationship between the taxonomical division of sections within genus and the amounts of VC in mature hips is closely related: VC contents in species of Sect. Cinnamomeae is rather high, more than 1000mg/100g, and relatively low in species of Sect. Synstylae and Sect. Pimpinellijbliae, less than 600mg/100g, except for R. platyacantha (2093mg/100g). The amounts of carotenes in hips showed a great variation: The highest contents of carotenes were found in R. fedtschenkoana (22.68mg/100g) and R. laxa (15.75mg/100g), the lowest in R. banksiae (0.1mg/100g) and R. roxburghii (0.1Smg/100g). Slight difference was found in the contents of vitamin E among species, ranging from 3.73mg/100g (R. henryi) to 1.45mg/100g (R. sericea) . The biological characteristics and possible application value of eight species were also evaluated.
