Wild edible plants of the Sikkim Himalaya: Nutritive values of selected species

Wild edible plants form an important constituent of traditional diets in the Himalaya. In the Sikkim Himalaya a total of 190 species have been screened as edible species out of which nearly 47 species come to the market. The present paper deals with nutritive values of 27 most commonly consumed wild edible plants in the Sikkim Himalaya. Of 27 plant species that were analyzed for their nutritive values, 22 were edible for their fruits and five for leaves/shoots. Among different plant parts, generally higher nutrient concentration was recorded for leaves, followed by new shoots and fruits. For different species the crude fiber content ranged between 2.15–39.90%, and the total soluble salts between 4.66–21.00%, and the vitamin C content from 6–286 mg/100 g. The fat content was determined high in the fruits ofCastanopsis hystrix, Machilus edulis, andCinnamomum species, while the protein content was highest inHippophae rhamnoides, Cucumis melo, andEleagnus latifolia. The total carbohydrate content ranged from 32–88% in the fruits of various wild edibles, the reducing sugar from 1.25–12.42%, total sugar from 2.10–25.09%, the lignin content varied from 9.05–39.51%, the hemicellulose between 25.63–55.71% and cellulose content varied from 9.57–33.19% in different species. Among the various macronutrients estimated in the plant samples of different wild edible species, nitrogen was present in highest quantity, followed by potassium, calcium, magnesium, phosphorus, and sodium. Micronutrients, such as iron, zinc, magnesium, and copper contents were analyzed in different plant parts of various wild edible species. The iron content was higher in leaves and new shoots. The nutritive values of certain wild edible species determined in this study are comparable with various commercial fruits. It is suggested that a few wild edible species need to be grown for commercial cultivation and adopted in the traditional agroforestry systems, which will lead to reduced pressure on them in natural forest stands as well as producing economic benefits for poor farmers.

Mi-cronutrients, such as iron, zinc, magnesium, and copper contents were analyzed in different plant parts of various wild edible species. The iron content was higher in leaves and new shoots. The study shows that wild edible plants are good source of nutrient for rural population, and also well comparable with various commercial fruits. It is suggested that a few wild edible species need to be grown for commercial cultivation and adopted in the traditional agroforestry systems, which will lead to reduced pressure on them in natural forest stands as well as producing economic benefits for poor farmers.     

拉祜族食用花卉的民族植物学研究

应用民族植物学的方法,对拉祜族的食用花卉进行了调查和研究,发现有相当多的花卉种类在一个狭窄的范围被一个单一的民族食用,实属罕见;首次全面报道了拉祜族食用花卉92种,分别属于37个科。其食用过程中的加工方法和烹调技巧都有讲究,食花的部位也有所选择。探讨了地域差别与食用花卉的异同,发现同一民族在不同地域环境或具有一定地理距离时,其选择的食用花种类有很大的不同,这与他们的生活习惯、居住环境及海拔高度有着极为密切的关系。有些植物分布区域很广,但不是分布区域内的同一民族都会选择食用它们;有些植物在不同的区域内虽然都被食用,但食用的目的和意义并不如一。还探讨了拉祜族食用花卉的重要性,以及其文化意义及开发利用前景。

The consumption ofTypha domingensis pers. (Typhaceae) Pollen among the ethnic groups of the Gran Chaco, South America

The gathering of Typha domingensis pollen and the modes of preparation and consumption edible products with it by seven ethnic groups of the Gran Chaco (Chulupí, Lengua, Maká, Mataco, Pilagá, Toba and Toba-Pilagá) in Argentina and Paraguay are described in this paper, together with those product’s local names and chemical compositions. Pollen provides an excellent food for those groups, because of both its nutritional value and its availability in periods when there is a scarcity of fruits and vegetables. The ethnic groups of the Gran Chaco do not eat any kind of pollen other than that ofT. domingensis.     

Genetic diversity in Taro (Colocasia esculenta Schott, Araceae) in China: An ethnobotanical and genetic approach

Taro,Colocasia esculenta (Araceae), is a widely distributed and important food crop in the humid tropics and subtropics. Relatively neglected by science, much knowledge of genetic diversity in taro is with farmers. Taro genetic resources managed by five ethnic communities and Han farming villages in diverse ecosystems were sampled and characterized in Yunnan Province, southwest China. This study documented a new type of flowering taro selected by farmers which is widely and intensively cultivated for its edible flower. Samples representing 20 traditional cultivars were grouped into five major morphotypes according to ethnobotanical, agro-morphological, and preliminary genetic characterization. Folk taxonomy and uses tended to confirm the five morphotypes recognized by peoples of Yunnan for their distinctive properties and uses. These major taro morphotypes are key units for assessing how patterns of use maintain genetic diversity and to monitor potential genetic erosion. The morphotype groups also suggest possible evolutionary relationships in cultivated taros.     

高黎贡山五加科的植物地理学研究

本文从属、种及地史文献资料三方面对高黎贡山五加科植物进行了植物地理学研究。结果表明：1．高黎贡山五加科植物包括15属56种及13变种。2．从起源来看,高黎贡山五加科植物以热带起源为主,热带属占66.7％(10属）,温带属占33.3％（5属）,而与地中海地区和中亚地区的联系十分微弱。3．从种的分布区式样来看：高黎贡山五加科植物以温带分布型为主,温带分布型的物种占全科种数的88.4％（61种）,这一统计结果与属的统计结果（66.7％)的属系热带属）形成很大的反差,其原因在于掸邦一马来亚板块上的高黎贡山植物区系源于赤道热带,在板块位移过程中,随着高黎贡山的北移,喜马拉雅山脉的强烈隆升,五加科这一起源于热带的古老木本植物,因不适于比赤道带冷得多的气候环境而先后被淘汰,部分属种则在新的环境中经过适应、演化和重新分化,除个别热带属的北缘种在高黎贡山北端独龙江河谷中幸存下来（如树参属Dendropanax)以外,其余新分化出来的植物则是温带性的（如常春木属Merrilliopanax),因此,现在高黎贡山五加科植物区系中,热带起源的属多于温带属,但温带种大大多于热带种。所有这些成分中,中国一喜马拉雅分布的成分(15种）和中国特有的成分（43种）构成了高黎贡山五加科植物区系的基本骨架,这些成分标志着高黎贡山五加科植物区系的东亚温带性质。4．高黎贡山五加科植物特有现象突出。一方面表现在种类丰富,计有中国特有类群22种和变种,云南特有类群12种和变种,高黎贡山特有类群9种,另一方面表现在特有类群的丰富度与纬度成正比,就高黎贡山特有种来说,北段（贡山）的特有类群（8种和变种）远远多于南段的腾冲（仅1种）。5．由于掸邦一马来亚板块位移对高黎贡山生物区系的影响,部分高黎贡山五加科植物从滇东南或滇南至高黎贡山的一些连续分布区被间断为滇西北与滇东南的对角分布式样（如少毛云南 木Aralia thomosonii var. glaerescens,单枝五叶参Pentapanax leschenaultii var.simplex,拟白背叶鹅掌柴Schefflerahy poleucoides),而与此同时,在云南形成了一条从滇西北一滇东南走向的生态地理对角线,由于该对角线的形成,导致部分五加科植物仅能在对角线以西及以南生存和繁衍（如大叶鹅掌柴Schefflera macrophylla)。     

拉祜族食疗花卉的研究

对拉祜族的食疗花卉进行了探讨.结果表明,拉祜族有着丰富的食疗花卉知识,其形成有着特殊的医药和文化背景以及朴素的早期传统民族医药特征;拉祜族民间普遍存在的花卉食疗现象,是对其生存空间内现有食物的自然选择结果,是传统知识的积累使然,是在与各民族相互学习交流中得到启迪而加以利用的结果,具有原住民文化特征,是民族文化多样性的重要组成部分.拉祜族食疗花卉约有53种,分别隶属于28个科,较有特色的花卉包括杜鹃花(Rhododendron spp.)、姜花(Alpinia spp.、 Amomum spp.、 Zingiber spp.)、山茶花(Camellia spp.)、蜜蒙花(Buddleja officinalis Maxim.)等.此外还探讨了拉祜族传统文化与当地自然资源及其生物多样性的关系,认为今天拉祜族聚居地还保留有丰富的森林植被和物种,与他们对自然资源的管理与合理使用有着密切的关系.

云南黑老虎不同种源氨基酸和其他指标的分析与评价

为探讨黑老虎（Kadsura coccinea ）作为果用食物的营养价值,对采自云南省不同产地的野生黑老虎果实分别测定其果皮和果肉中的维生素 C、可溶性固形物、氨基酸、粗纤维、蛋白质、总糖等含量,并进行比较分析。结果表明：野生黑老虎果实含有丰富的人体必需的氨基酸,4个种源中,以勐海的黑老虎果肉中各人体必需氨基酸总含量最高,为0．256％,其次是屏边种源,为0．106％,景东种源为0．0943％,普文种源氨基酸总含量最少,为0．0274％。黑老虎果实还含丰富的维生素 C、粗纤维、蛋白质、总糖等。不同产地之间或单株之间各营养指标变化范围大,变异系数较高,优良种源或优良单株可选择性较强。果肉的养分灰关联度以勐海种源和第2单株最高,将作为备选优良种源和优良单株。     

中国九个人群耵聍的遗传多态性

报道了九个人群的耵聍位点基因。计算表明中国各族人群在耵聍位点上的遗传分化程度非常大,固定指数F_(ST)=0.22。本文根据耵聍基因频率在我国和邻近地区的分布趋势,认为亚洲东北地区应是干型基因的起源地,目前世界上耵聍位点基因频率分布格局主要是基因扩散的结果,而非选择作用造成的。     

Edible wild plants of the Chorote Indians, Gran Chaco, Argentina

The Chorote Indians are hunter-gatherers and fishermen from north-west Argentina and south-west Paraguay who belong to the Mataco-Maká linguistic family. Their edible plants are identified by botanical and vernacular names, the parts employed and modes of preparation and consumption. The Chorote people use 57 plant species as a source of food, which they consume in 118 different ways. Five new edible species, that yield seven plant foods, are reported here for the first time for Chaquenian ethnic groups. However, only a few wild plant foods are in frequent use today, with most being used occasionally, infrequently or not at all. A cross-cultural comparison with four neighbouring ethnic groups reveals that one third of their plant foods are exclusive to the Chorote people, despite the fact that they share most of their edible plants with the other groups. This article is the first contribution to an understanding of the Chorote's ethnobotany and to a comparison of interethnic relationships concerning their edible plant resources.  © 2007 The Linnean Society of London, Botanical Journal of the Linnean Society , 2007, 153 , 73–85.

应用民族植物学的方法,对生活在云南西部高黎贡山东坡的勒墨人进行了调查。主要研究结果如下勒墨人对野生植物及环境有较大的依赖性;从 事刀耕火种轮歇栽培,并种植漆树(Toxicodendron vernicifiuum)和桤木(Alnus nepalensis)以促进轮歇地的休闲管理;栽培和管理漆树、收割生漆交换或出售,是勒墨人轮歇农业的一大特色;他们采集利用60余种野生食用植物和100余种药用植物,云黄连(Coptis teeta)和贝母(Fritillaria cirrhosa)等重要药材用于同外界进行物资交换;在对自然界的崇拜过程中,勒墨人对当地生物多样性的保护起到了积极的作用。     

New Constituents from the Low Polar Fraction of the Fruits of Crataegus dahurica and Their Anti‐Inflammatory Activity in RAW264.7 Cells

The fruit of Crataegus dahurica Koehne was used to treat the disease of infantile indigestion and dyspepsia as an ethnic medicine and food. As a continuous work on finding the active constituents from the edible herbs, four new biphenyl derivatives ( 1 – 4 ), together with two known compounds ( 5 and 6 ), were obtained from the petroleum ether fraction of the fruits of C. dahurica. Their structures were determined by the extensive 1D and 2D NMR spectra and HR‐MS spectrometry. Furthermore, the anti‐inflammatory activities of all the isolated compounds were investigated, in which compound 4 showed moderately inhibitory effects on NO production in RAW264.7 cells without inducing cytotoxicity.

白族群体间的Y染色体和线粒体DNA多态性的分析

从父系和母系基因库水平上,研究不同分布地区白族群体之间的遗传结构的异同,并对其族源以及本民族群体之间的微进化关系进行初步的探讨。利用PCR-RFLP方法对云南白族和湖南白族及云南的傣族、布依族、独龙族、怒族、阿昌族和湖南土家族共8个群体进行14个线粒体多态位点和Y染色体上的13个双等位基因位点进行基因分型。统计单倍型,在SPSS软件上进行主成分分析。结果显示,两个白族群体在Y染色体双等位基因单倍型分布上差异不大,以H6、H8为主要单倍型分布;在线粒体单倍群分布上,两个白族群体则差异显著,单倍群D、B、M8在湖南白族中的分布频率比云南白族高的多,而在云南白族中M^*、G、F的频率则比湖南白族高。对Y染色体单倍型分布频率进行主成分分析表明两个白族群体聚在一起,整体上和其他北方起源的群体聚成一组;而对线粒体的单倍群分布频率分析显示湖南白族接近湖南汉族和土家族,而云南白族则接近云南怒族和阿昌族。两个白族群体在父系遗传结构上相近,表明他们具有共同的父系族源;而母系遗传结构上的差异,可能与历史上迁到湖南的白族先民主要为男性军士,流寓到当地后与汉、土家等民族女子通婚所致。
