Abstract
Focusing on licorice, a highly used raw material in health foods, quantitative analysis of functional/medicinal components and a safety and functional evaluation was carried out for herbal medicines, health food ingredients, and so-called health foods. A functional component, glabridin, was detected in herbal medicines from Glycyrrhiza glabra and G. inflata, health food ingredients, and in commercially available health foods that contain licorice. Likewise, glycyrrhizin, a medicinal component, was detected in these sources, except in licorice oil extract. Estrogen activity in vitro was detected in some of the herbal medicines, health food ingredients, and in health foods containing licorice. In the in vivo study, liver weight in ovariectomized (OVX) mice treated with licorice oil extract was significantly higher than that in OVX and sham mice in a dose dependent manner. These results suggest that excessive intake of licorice oil extract from health foods should be avoided, even though these ingredients might be beneficial for medical use in order to maintain bone health in postmenopausal women. Measurement of hepatic cytochrome P-450 (CYP) activity, reproductive organ weight, and fat and bone mass in OVX mice was considered useful for evaluating the safety and efficacy of estrogenic health food ingredients derived from herbal medicines.

Abstract
Glycyrrhiza uralensis roots used in this study were produced using novel cultivation systems, including artificial hydroponics and artificial hydroponic-field hybrid cultivation. The equivalency between G. uralensis root extracts produced by hydroponics and/or hybrid cultivation and a commercial Glycyrrhiza crude drug were evaluated for both safety and efficacy, and there were no significant differences in terms of mutagenicity on the Ames tests. The levels of cadmium and mercury in both hydroponic roots and crude drugs were less than the limit of quantitation. Arsenic levels were lower in all hydroponic roots than in the crude drug, whereas mean lead levels in the crude drug were not significantly different from those in the hydroponically cultivated G. uralensis roots. Both hydroponic and hybrid-cultivated root extracts showed antiallergic activities against contact hypersensitivity that were similar to those of the crude drug extracts. These study results suggest that hydroponic and hybrid-cultivated roots are equivalent in safety and efficacy to those of commercial crude drugs. Further studies are necessary before the roots are applicable as replacements for the currently available commercial crude drugs produced from wild plant resources.

Abstract
The leishmanicidal compounds isolated from whole plants of Elephantopus mollis H.B.K. were identified as follows. Three new sesquiterpenoid lactones, 2,5-epoxy-2beta-hydroxy-8alpha-(2-methylpropenoyloxy)-4(15),10(14),11(13)-germacratrien-12,6alpha-olide, (4betaH)-8alpha-(2-methylpropenoyloxy)-2-oxo-1(5),10(14), 11(13)-guaiatrien-12,6alpha-olide and (4betaH)-5alpha-hydroxy-8alpha-(2-methylpropenoyloxy)-1(10),11(13)-guaiadiene-12,6alpha-olide, were isolated from Peruvian and Brazilian collections together with four known sesquiterpenoids, molephantin, elephantopin, isoelephantopin and 2-deethoxy-2beta-methoxyphantomolin. They exhibited potent in vitro leishmanicidal activities against Leishmania major. The alpha-methylene-gamma-butyrolactone moiety was found to be essential to the potent leishmanicidal effect observed.

Abstract
Clerodane glycosides and flavonoids in Dicranopteris pedata and three varieties of D. linearis were investigated. All the ferns contained a new glycoside, (6S,13S)-6-[6-O-acetyl-beta-D-glucopyranosyl-(1-->4)-alpha-L-rhamnopy - ranosyloxy]-13-[alpha-L-rhamnopyranosyl-(1-->4)-beta-D-fucopyra nosyloxy]- cleroda-3,14-diene, as a chemical marker of this group. Flavonoids were limited to flavonol 3-O-glycosides. The ferns and isolated flavonoids are as follows; D. pedata: afzelin, quercitrin. D. linearis var. brevis: afzelin, quercitrin. D. linearis var. tenuis: quercitrin, isoquercitrin. D. linearis var. sebastiana: astragarin, isoquercitrin, rutin, kaempferol 3-O-(4-O-p-coumaroyl-3-O-alpha-L-rhamnopyranosyl)-alpha-L-rhamn opy ranosyl- (1-->6)-beta-D-glucopyranoside.

Abstract
A new chemotype of Microlepia marginata, P-type strain, was found in the Central districts of Japan. The two main constituents were characterized to be 2 beta,15(R),16-trihydroxy-ent-pimar-7-en-3-one (fumotoshidin A) and 3 alpha-alpha-L-arabinofuranosyloxy-15(R),16-dihydroxy-ent-pimar+ ++-7-ene (fumotoshidin arabinoside). The young fronds of this strain have reddish stripes, which is a common feature to Y-type strains also containing ent-pimarane-type glycosides.
