    Six constituents were isolated from the roots of Sageretia gracilis Dunn et Spr., a anti-tumor plant in Yunnan. On the basis of spectrometric analysis (IR. NMR. MS.) and preparation of derivatives, five of them were identified as hordenine (I), syringic acid (), vanillic acid (), 6-sitosterol and palmitic acid. The anti-tumor activity of hordenine (I) is explemented as 50.5% for S 180.

    In China, Tsuga forest had been regarded as one of the intrazonal vegetations for a long time. Through further investigation of the south-west alpine forest regions of China in recent years. We firmly be1ieve that the tsuga forest occupies more important position than the Picea forest in the veltical zones of alpine vegetation. The lower limit of its distribution is usually connected with the subtropical evergreen broad-leaf forest, and the upper limit with the Picea and Abies forests. It is a real kind of evcrgrcen-coniferous forests with adaptation to moist--temperate habitat, by which the characteristics of subtropical mountai-nous vegetation of China may be tated. After studying of the species distri-butions, habitat factors, community characteristics and economic worth of Tsuga forest synthetica11y, it may be classified intQ four forgh4tions and more divi-ding units.

    The essential oil of roots from Valeriana iatamansi Jones was analysed qualitatively and quantitatively by means of fractional distillation, silican gel or alumina column chromatography, TLC, GLC, chemical and spectrometric methods. Eight components have been identified,limonene (0. 8%). l, 8-cineole (0. 3%), Plcymene (1 .2 %), borneol acetate (7. 2%), borneol, (4. 5%), nerolidol (1.0%), maaliol(11.6%).

    We cultivated some Mangos from Pakistani seeds during 1972 at Yuanjing county in Yunnan Province. There were only four numbers with no denomination of varieties attached. Out of more than 100 seedlings, we selected 21 and planted them at the Mango plantation. Some of them began to blossom and fruit at 1976, and good harvest was obtained at 1978, During 4 years observation, we selected some seedlings and gave their names at: "Gan Lu", "Huang Pi Da Tou", "Mi Yan Mang", "Qin Pi Xiang", and "Qiang Jiang".They have grown robustly with a high yield of fruits and a low percen-tage for fallen. They have possessed the resistance of fungi and insects. Some of them (of seven-years age) yielded 35 up to 105 Kgs.

    Guar bean (Cyamopsis telragono1oba (L) Taub.) is native to tropical Africa and now cultivated mostly in the dry, semiarid regions of India and Pakistan. Guar gum is widely used in petroleum industry in the world.It was introduced successfully to China in 1974. The experimental results indicated that petroleum production could be increaced when guar gum was used; the seeds maintained the characters of high gum content and good quality.The results also indicated that the by products of guar bean could be uti1ized comprehensively.

    Huanghuahaosu is a new substance isolated from the leaves and flowers of Artemisia annua Linn. and A. annua Linn. f. macrocephala Pamp. It possesses higher and quicker effect and lower as compared with other anti-malaria medicines. More than 2099 patients who were infected with cerebral malaria, pernicious malaria jtertiana and antichloroquine malaria have been tested with Huanghuahaosu and the clinical effect is l00%.

    Yunnan is a mountainous plateau which is controlled by tropical monsoon.The whole relief of Yunnan is high in the north and low in the south. Even though the altitude declines with the latitude from north to south, the horizontal differentiation is evident and each zone of vegetation latitudinally distributes over a hundred kilometres. Therefore, it may be cal1ed "horizontal zones of the mountainous plateaus type".The major zonal vegetation changes from the south to north as follows:tropical rain forest and monsoon forest -molisoon evergreen broad-leaf forest in southern part of subtropical zone - semi-humid evergreen broad-leaf forest in northern part of subtropica1 zone. Each of these vegetations are distributed in the basin of plateau or in the wide valley and the lower slope of the mountains surrounding these basins, where, the level of horizonta1 zones are founded.

    Both grevillic(2,5-dihydroxy-trαns-cinnamic) acid and grevillone(6- hydroxycoumarin) were only found from Grevillea robusta A.Cunn.(Protea- ceae)thus far in the plant kingdom.It is of interest from biogenetic viewpoint that their hydroxylation pattern shows to be quite special.Basically, the problem of the biogenesis of grevillic acid and grevilione is this: by what enzymic pathway is this special hydroxylation pattern formed from trans-cinnamic acid in the plant?In the present paper,an attempt is made to suggest the mechanism of the possible biosynthetic pathway for conversion of trans-cinnamic acid via grevillic acid to grevillone in the plant.Our suggestion is based on evidenceof an indirect and structural character, and not purely speculative.
