A previous study by the authors showed that the body scent of men who have greater body bilateral symmetry is rated as more attractive by normally ovulating (non-pillusing) women during the period of highest fertility based on day within the menstrual cycle. Women in low-fertility phases of the cycle and women using hormone-based contraceptives do not show this pattern. The current study replic...

Many recent studies attempting to assess the biochemical connections between anthocyanin biosynthesis and floral scent production have yielded limited insights due in part to a focus on either field phenotypes of unknown genetic background or artificial genetic manipulation. In this study, we seek to more precisely explore the mechanistic connections between floral scent and color in Ipomoea pu...

In conjoining the disciplines of "ethology" and "chemistry" the field of "Ethochemistry" has been instituted. Ethochemistry is an effective tool in conservation efforts of endangered species and the understanding of behavioral patterns across all species. Chemical constituents of scent-markings have an important, yet poorly understood function in territoriality, reproduction, dominance, and imp...

Floral scent is a key component of floral display, and probably one of the first floral attractants linking insect pollinators to the radiation of Angiosperms. In this article, we investigate floral scent in two extra-tropical genera of Annonaceae. We discuss floral scent in the context of differing pollination strategies in these genera, and compare their scent to that of a close tropical rela...

The enormous species richness of flowering plants is at least partly due to floral diversification driven by interactions between plants and their animal pollinators [1, 2]. Specific pollinator attraction relies on visual and olfactory floral cues [3-5]; floral scent can not only attract pollinators but also attract or repel herbivorous insects [6-8]. However, despite its central role for plant...

Background:  Nanostructured lipid carriers (NLCs) of sumatriptan succinate (SS) were prepared by using lavender oil.  In ancient days, lavender oil was used for the treatment of a migraine. The natural anti-migraine agent, lavender oil, combined with an anti-migraine drug such as SS in a nano-formulation, will be a practical alternative approach in migraine therapy.  Objective: NLCs of sumatri...

The essential oil content in the inflorescence of lavender (Lavandula angustifolia Mill.) cultivated in the mid hills of Uttarakhand was found to be 2.8 % based o n the fresh weight. The oil was an alysed by capillary GC and GC– MS. Thirty seven constituents, representing 97.81 % of the o il were identified. The major components of the oil were linalyl acetate (47.56 %), linalool (28.06 %), lav...

Background Dysmenorrhea is an important disease that affects physical, social and psychological functioning such as social, emotional and health performance. The lavender essential oils are being used in both combined and mere forms. The purpose of this meta-analysis is to investigate the...

This study evaluated the effects of inhalation of Lavender essential oil on the pain of open-heart surgery. The main complaint of patients after open-heart surgery is chest pain. Due to the side effects of opioids, it is important to use a non-invasive way to effectively relieve pain including aromatherapy with analgesics. This study is a clinical single-blind trial. The study was conducted on ...
