    This paper shows the chenical constituents of the essential oil from Limnophila rugosa (Roth)Mwrr.By the aid of PGC,GC-MS and IR, the following components have been separated and identified; linalool (0.08%),estragole (21.94%),cis-anethole (0.03%),anisaldehyde (0.05%),trans-anethole (76.39%),anisyl acetine (0.03%),caryophyllene (0.08%),hu-mulene (0,15%)and α- bulnesene (0,01%0.This incestigation will provide scientific basis for futher development and utilization of the essential oil of Limno phila rugosa.

    The acid labile nature of ginsenosides,the saponins isolatid from ginseng and Sanchi-Ginseng [Panax notoginseng (Burk.)F.H. Chen]which is also a famous chinese traditional medicine, was observed on an early study on ginsenosides.ln this paper, we report that water solutions of ginseno ide Rb1, Re, RG1, and notoginsenoside R1 decomposed under the condition of heating on water bath to yield prosapogenins,which were shown to de mix-tures of C-20 epimer of ginsenoside Rg3,

    The present paper reports the light germination testson the seeds of 24 speeies of Rhododendron. The main conclusions are as follows: The seede of Rhkododendron. are light-requiring seed .Germination of all the seeds needs ligh,if the seeds are tested in darkness, the germination percent will be almost zero. Germination of Rhododendron seeds is controlled by phytochrome.Red light promotes the germination.The promotning effect qulity of the last irradiation.

    This paper indicates the effects of hormone, light, temperature and time of incubation on anthocyanin contint in plantlets of Begonia fimbri-stipula Hance on uitro.NAA of concentration from 0.125 mg/l to 1.0 mg/l could increased anthocyanin content,0.125 mg/l had the best effect.BA,2ip, ZT decreased anthocyanin content. Light had a marked effects to enhance anthocyanin content of the plantlets ln the range of experiments anthocyanin content increased with the irradiation intensity. The effects of blue, white, red light used alone of conbinatly were combinatoy were compared, the effect of enhancing the

    The present paper deals with the classification and distriburion of the genus lsometrum Craib (gesmeriacece_____Cyrtandroion) and its rela-tionship with the genus Ancylostemon.The genus under discussion is endemic to China,consisting of ll species (incl.4 new species,one new combination and 2 new varieties)which are grouped into two sections.lts area is rather small,confined to northwestern to eastern Sichuan, the Qinling Range,Daba Range and the mountainous region of western Hubei,with the concentration in northwestern Sichuan. Most species grow on shady and moist rocks and cliffs at the altitude of 500--2000 m,but one or two species occur at the altitude of 2200-2800 m,sometimes even up to 3900 m alt.
