The sulfur-rich anal sac secretion of the mink,Mustela vison, consisted of immiscible lipid (1.7% sulfur) and aqueous (0.7% sulfur) phases. Light and electron microscopy revealed secretory tissue of two types, sebaceous (holocrine) and apocrine. A major input of sulfur into the sac appeared to be associated with glycoprotein granules present in the apical(More)
The sec re t ion was obtained by ext rac t ing the su r face of the gland a r e a with e ther using 30 fully grown males in the per iod of the autumn s laughter in Sweden (20-25 mg f r o m each individual). P r e l i m i n a r y infor mation on the chemical composi t ion of the mixture was obtained by the methods of TLC on "Silufol" s i l ica gel in n h e x(More)
The qualitative and quantitative composition of the principal lipid constituents of Siberian musk deer (Moschus moschiferus) preputial gland secretion, main odor carriers and potential precursors of odorous substances, was investigated by means of high-performance liquid chromatography. Free fatty acids and phenols (10%), waxes (38%), and steroids (38%)(More)
Apart f r o m the g lycos ides that we isola ted p rev ious ly [1], f r o m the roo ts of C. officinalis L. by chroma tography on a column of s i l ica gel followed by desal t ing with an a n i o n e x c h a n g e r e s i n (Dowex 50 W x 2 100/200, H + form) we have obtained the following minor glycosides: calenduloside G, C42H66014 • 2H20 (I), mp(More)
The structure of new triterpene glycosides from the roots of potmarigold calendula (C. officinalis) has been established: oleanolic acid 3-{[galactopyranosido-(1→3)] [glucopyranosido-(1→2)]-β-D-glucopy-ranoside} (calenduloside C) and the 28-acyl-β-D-glucopyranoside of calenduloside C (calenduloside D).
We have p rev ious ly repor ted the s t ruc tu re of a mort .s ide and a bioside (calenduloside A) of oleanolic acid isolated f r o m the roo t s of Calendula offieinalis L. [1, 2]. In the p r e s e n t paper we give information to es tabl i sh the s t ruc tu re ofcalenduloside B a t r ios ide of oleanolic acid with mp 232-234° C (methanol), [(~]~ + 57.2 °(More)
Every individual has a unique odor, which can be identified by both conspecifics and representatives of other species. However, the necessary and sufficient key substances coding an individual thus far have not been found among volatile excretions of individuals (olfactory stimuli); nor have the main mechanisms of individual identification by order been(More)
The t r i t e rpene glycoside theasaponin isolated f rom the seeds of Thea s inensis L. (tea) has been inves t iga ted repea ted ly [1-3, 5-8]. Udea [1] found that the aglycone is a hexahydroxyor pen tahydroxy-f l amyr in , es te r i f i ed with 1 mole of angelic acid, and the ca rbohydra te par t consis ts of glucuronic acid (GA), ga lac tose (Gal) , a rab(More)
