The antioxidative activity and the related parameters of hot water extracts obtained from 16 medicinal plants were tested. The extraction yield was the highest in Salvia miltiorrhiza Bunge $(36.49\%)$ pH range was $4.00\~5.92$ in all samples. Absorbance at 280 nm was examined to determine aromatic compounds content. The absorbance of $250{\mu}g/mL$ sample was the highest in Prunella vulgaris Linne var. lilacina Nakai (2.872) and below 0.5 in Cirsium maackii, Crataegus pinnatifida Bunge and Zizyphus jujuba Miller. Also, absorbance at 420 nm was high in order of Prunella vulgaris Linne vu. lilacina Nakai (1.312), Zea mays Linne (0.917) and Inula japonica Thunberg (0.725) Total phenolic compounds contents was the highest in Prunella vulgaris Linne var. lilacina Nakai $(5.07{\pm}0.05\;mg/100g)$ and flavonoids contents was 2-fold higher in Salvia miltiorrhiza Bunge $(4.82{\pm}1.16\;mg/100g)$ than the other samples. Electron donating abilities of Zizyphus jujuba Miller, Cornus officinalis Siebold et Zuccarini and Salvia miltiorrhiza Bunge were over $90\%$ at $1000{\mu}g/mL$. Reducing power had similar tendency to electron donating ability while reducing power was significantly lower in samples compared to BHT. Two samples (Prunella vulgaris Linne val. lilacina Nakai and Inula japonica Thunberg) were found to have more than $50\%$ nitrite scavenging effect at $500{\mu}g/mL$ while 8 kinds samples (Zizyphus jujuba Miller, Cornus officinalis Siebold 81 Zuccarini, Chrysanthemum indicum Linne, Prunella vulgaris Linne var. lilacina Nakai, Inula japonica Thunberg, Acanthopanax sessiliflorum Seeman, Salvia miltiorrhiza Bunge and Curcuma longa Linne) showed more than $50\%$ nitrite scavenging effect at $1000{\mu}g/mL$. Prunella vulgaris Linne var. lilacina Nakai showed significantly stronger nitrite scavenging effect than other samples, and its activity was $59.62{\pm}1.573\%$ and $80.58{\pm}0.300\%$ at concentrations of 250 and $1000{\mu}g/mL$, respectively.

The distribution of orbicules was investigated for eleven taxa of six genera in Lamiaceae and four taxa of three genera in Verbenaceae using scanning electron microscopy. A literature survey to evaluate the phylogenetic potential of the orbicules and their possible correlations with tapetum types was also conducted. The orbicules are consistently absent in all investigated taxa of Lamiaceae, while small orbicules of an average size of less than $1{\mu}m$ are densely distributed in Verbenaceae. In fact, orbicules appear consistently in 123 of 150 angiosperm families when investigated in at least one species. Thus, the distribution patterns of orbicules could be a useful diagnostic character in angiosperms. In addition, orbicules occur in 84% taxa of the secretory tapetum type, while they are commonly absent in the amoeboid tapetum type (ca. 80%). The presence of orbicules may be correlated with the secretory tapetum type. However, the study of orbicules is restricted in 150 families and the tapetum type within these families can be applied for 92 families out of a total of 416 angiosperm families. Thus, further investigation of orbicules is necessary in extended taxa to address the questions pertaining to orbicules.

This study was conducted with n-hexane extracts of sensitive plant Mimosa pudica, mexican poppy Argemone mexicana, panimarich Leucus aspara, water pepper Polygonum hydropiper and shialmutra Blumea lacera weeds against pulse beetle Callosobruchus chinensis (Coleoptera: Bruchidae) for protection of mung bean Vigna radiata grains. The $LC_{50}$ values of the weed extracts ranged from 4.5 to 6.4, 4.1 to 5.6 and 3.6 to 5.5 g/100 mL at 24, 48 and 72 hours of post treatment, respectively. The extracts showed 35 to 69% fecundity and 33 to 63% adult emergence inhibitory effect on the pest, and revealed 13 to 49% grain protection of mung beans. Insect mortality, fecundity and adult emergence inhibitory effects, and grain protection activity increased with increased concentration of the extracts. The shialmutra followed by water pepper extracts revealed better performances in fecundity and adult beetle emergence inhibitory effect compared to the other weeds. The findings proved that the n-hexane extracts of the five weeds are sources of botanical insecticides which may be used in the integrated management of C. chinensis.

These researches have been conducted to obtain the basic information of the effects of paraquat on plant species and to screen the plant species showing specific responses to paraquat. Paraquat resistance related to ecotype and overwintering capacity. Perennial and biennial species showed higher resistance than annual species. In a family, most species showed higher resistance were overwintering species. Lamiaceae, Brassicaceae, and Caryophyllaceae were tolerant to paraquat, whereas Poaceae and Asteraceae were sensitive. Especially Mosla dianthera of Lamiaceae, Hemistepta lyrata and Aster pilosus of Asteraceae, and Paspalum thunbergii of Poaceae showed higher tolerance than others. The response patterns of plant species on germination stage were different to those on vegetative stage. Germination of Amarathus lividus, Arabis glabra, and Bidens frondosa was not inhibited by paraquat. But their seedling growth were highly inhibited.
