By using a suitable sample preparation, free and bound phytoestrogens (daidzein, equol, genistein, formononetin, coumestrol and biochanin A) can be isolated from extracts of fresh plant material and subsequently quantified by HPLC at different wave lengths. Chromatographic peaks assigned to phytoestrogens were identified by retention time and by comparison to the addi-tion of standards.

Five new iridoidal glycosides, gentioumosides A-E were isolated from the whole herb of Gentiana urnula. Their structures were elucidated mainly by spectral methods. Among which gentioumosides A-C are bis-iridoidal glycosides while gentioumosides D and E are loganin type ones. It is noted that all the glycosides possess a 2,3-dihydroxy benxoyl unit or its derivative in the molecule.

A new compound named australisin (1) was isolated from the whole herb of Acalypha australis L. (Euphorbiaceae). Its structure was established by a spectroscopic analysis. In addi-tion, β-sitosterol and daucosterol were also obtained.

A new acyi sugar along with four know iridoidal and phenyl propanoid glycosides, harpagoside, harpagide, 0-methyl catalpol and angoroside C, were isolated from the roots of Scrophularia ningpoensis Hemsl., a famous traditional Chinese medicine known as "Xuan-Shem". By means of chemical and spectral evidence its structure was elucidated as 4-0-(p-methoxycinnamoyl)-α-L-rhamnopyranose.

Nine compounds, which include a C-glucosyi flavonoid, isoorientin; a xanthone glycoside, swertianolin; a lignan glycoside, oivil 4'-O-β-D-glucose; a stright chain fatty alcohol, n-1-triacontanol; three iridoidal glycosides, gentiopicroside, swertiamarin and loganic acid; a triterpenoid, oleanolic acid and a sterol, daucosterol were isolated from the whole herbs of Gentianella azurea. The structures of these compounds were determined by means of spectral and some chemical evidence.

Two steroidal saponins were isolated from the rhizome of Aspidistra elatior. On the basis of detailed chemical and spectrascopic evidence, their structures were elucidated to be diosgenin-3-0-[β-D-glucopyranosyl(l-2)-[β-D-xylopyranosyl(l-3)]-β-D-glucopyrano-syl(1-4)-β-D-galactopyranoside(aspidistrin)and neobotogenin-3-0-[β-D-glucopyranosyl(l - 2)]-[β-D-xylopyranosyl(l- 3)]-β-D-glucopyranosyl(l- 4)-β-D-galactopyranoside respectively. The latter is new steroidal saponin and named a neoaspidistrin.

Three polysaccharides, namely AP-1, AP-2, AP-3, which were proved to be homo-geneous by glass fiber paper electrophoresis, ultracentrifugation analysis and gel chromatography, were isolated from the stems of Dendrobium aphyllum. The limiting viscosity numbers of three polysaccharides were 426.96, 416.96 and 234.03 respectively. Their molecular weights (Mw) were 86300, 61500 and 43100 respectively.

A new antifugal protein named EAFP was isolated with 0.5 mol / L NaCI from the bark pieces of Eucommia ulmoides Oliv and purified by ammonium sulfate fractionation, carboxymethylcellulose ion-exchange chromatography and Bio-gel-p-10 gel filtration.

After examining the anatomical characters of the rhizomes of 27 species belonging to 5 genera of Chinese Arthrostylidiae, the authors discorved that the rhizomes, especialy the culm necks, have some taxonomic importance in the tribe. According to the characters of rhizomes to-gether with those of the other organs, the authors descussed the interrelation among the 5 genera and supported to keep these genera separate.

Change of water physiology of potted plants Cymbidium sinense (Andr.) Willd. grown in different soil moisture condition were studied. Different age of leaf had different response to drought, 1-year-old leaf was sensitive than 2-year-old leaf. Among several physiological parameters, such as leaf water content, leaf water potential, chlorophyll content, transpiratory rate and stomatal resistance etc., last two parameters were the most sensitive to drought.

This article describes the anatomical features of the embryos of 13 species of bamboo fruits, discusses the significance of these features in systematical classification as well as the status of each species in the classification system. As experiments proved, the embryonic types of the bamboo fruits are varied and complicated, which evinces the limitation of the previous definition of theembeyo types of the Bambusoideae as F+PP type.

The anatomy of secondary phloem and periderm in eight host species of Kerria yunnanensis Ou et Hong is described, the eight species include Flemingia macrophylla (Willd.) Merr., Pueraria wallichii DC., Ficus variegata W. var. chlorocarpa King, Alblizia bract eat a Dunn, Samanea saman (Jacq.) Merr., Butea monosperma (Lam.) Taub., Ziziphus mauritiana Lam. and Schleichera oleosa (Lour.) Oken. The axial system of their secondary phloem consists of sieve tubes, companion cells, phloem parenchyma cells and fibres.

In present paper, pollen morphology of seven species of the genus Tongoloa from China was studied. They are concentrated in the Hengduan Mountains and some species extend to nearby area. The pollen grains were examined under LM and SEM. The result shows: They are rhomboidal types except T. dunnii (Boissieu) H. Wolffand T. silaifolia (Boissieu) H. Wolff which are rectangular type. All the pollen grains are not original or typical rhomboidal types. T. gracilis H. Wolff, T. elata H. Wolff are presented various shapes i.e. subrhomboidal. subelliptical and subrectangular. This is a differential rhomboidal type. So we may consider that the evolutionary trends of pollen types were from rhomboidal type to rectangular type in the genus Tongoloa H. Wolff. In our earlier paper we touched similar pollen morphology in the genus Physospermopsis H. Wolff. The pollen information suggest that Tongoloa H. Wolff may be closely related to the genus Physospermopsis.

The present paper deals with karyotype analysis of Callitris preissii, C. verrucosa and C. endlicheri (Cupressaceae) endemic to Australia for the first time (except C. preissii). Their morphology of somatic chromosomes in seed root-tip cells, chromosome measurements and dia-grams are shown in Fig.
