چکیده
Until now only six out of the 51 species which constitute the genus Packera (Weber and LoK ve, 1981) had been studied chemically (Pettit et al., 1980; Bohlmann et al., 1981; McCoy et al., 1983; Zalkow et al., 1988; PeH rez et al., 1991; Bah et al., 1994). In order to contribute to the chemistry of the genus, we decided to study Packera coahuilensis (Grenm.) C. Je!rey (MEXU 781268) and Packera bellidifolia (HBK) Weber and LoK ve (MEXU 781267), collected in Coahuila, October 1996, and in Oaxaca, June 1997. Voucher specimens are deposited at the Herbarium del Instituto de BiologmHa, UNAM.

The Operations of a Lethal Factor in Apotettix Eurycephalus (Grouse Locusts).
This paper deals with (1) the discovery in Apotettix eurycephalus Hancock of an autosomal lethal factor linked with those for the dominant, elementary color patterns, (2) the approximate, uniform stage of embryonic development attainable by the homozygous lethals, and (3) the apparently increased viability and probably vigor of individuals heterozygous for the lethal over sibs homozygous for it...
متن کاملSynopsis of Nekemias Raf., a segregate genus from Ampelopsis Michx. (Vitaceae) disjunct between eastern/southeastern Asia and eastern North America, with ten new combinations
The genus Nekemias (Vitaceae) was first recognized by Rafinesque in 1838. It has been treated as a synonym of Ampelopsis Michx. Recent phylogenetic studies suggest that Ampelopsis as traditionally delimited is paraphyletic. To maintain the monophyly of each of the genera of Vitaceae, we herein segregate the Ampelopsissect.Leeaceifoliae lineage from Ampelopsis and recognize these taxa in Nekemia...

متن کاملImmunomodulatory effects of Pseudostellaria heterophylla (Miquel) Pax on regulation of Th1/Th2 levels in mice with atopic dermatitis
Pseudostellaria heterophylla (PH) has various pharmacological effects that include immunologic enhancement and anti‑oxidation. However, it remains unclear whether PH exerts beneficial effects in dermatological diseases. The present study examined the effects of PH on a 2,4-dinitrochlorobenzene (DNCB)‑induced atopic dermatitis (AD) mouse model and elucidated its underlying mechanism of action. P...
متن کاملChemical Constituents and Antioxidant Capacity of Ocimum basilicum and Ocimum sanctum
The chemical constituents of leaves, inflorescence, and flowers from Ocimum basilicum (Thai basil) and Ocimum sanctum (Holy basil) were analysed by gas chromatography-mass spectrometry. The chemical compounds were extracted by hydrodistillation, headspace-solid phase microextraction, and solvent extraction. The main constituents of Ocimum basilicum were identified to consist of estragole (...
