Plant Growth Regulation

Some chemical compounds in petroleum ether extract ofMikania micranthaH.B.K. can strongly influence seedling growth ofPhaseolus radiaus. In this study, we provide evidence that the chemical compounds in active fraction chromatographed on normal phase silica gel columns from petroleum ether extract ofM. micranthahave strong activity to promoteP. radiaustaking root. But meanwhile, these chemical compounds could be inhibitors forP. radiausroot growth. Two main chemical constituents, α-Bisabolol and Eudesma-5,11(13)-dien-8,12-olide, in the active fraction were confirmed by GC-MS analysis.

Undecenoic Acid

Nine compounds were isolated from the petroleum ether extract of Euphorbia altotibetica. The structures of these compounds were elucidated as: squalene (1), β-sitosterol acetate (2), 11, 15, 19, 23-tetramethy-5, 9, 17-tetracosatrienoic acid (3), physcion (4), (z)-10-nonadecenoic acid (5), (z)-4-undecenoic acid (6), β-sitosterol (7), (24S)-stigmastan-4-en-3-one (8), naringenin (9). These compounds were identified on the basis of comparing their NMR datas with those of corresponding compounds in the literature.

Background: The fruits with the seeds of Dracunculus vulgaris Schott. (Araceae) are used against inflammatory diseases in Turkey. Objective: Present study was designed to justify this folkloric usage type of the plant. Therefore, the aim of this study is to investigate the anti-inflammatory activity of D. vulgaris. Methods: Petroleum ether, ethyl acetate and methanol extracts were prepared from the fruits, successively. Carrageenan-, serotonin-, and prostaglandin E2-induced hind paw edema; acetic acid–induced capillary permeability and 12-O-tetradecanoyl-phorbol-13-acetate–induced mouse ear edema models were used to assess the antiinflammatory activity of the extracts. The analgesic activity was experienced by using p-benzoquinone-induced abdominal constriction test. Results: The petroleum ether extract displayed the highest activities in all of the used test models compared with the control group. Therefore, the constituents of this extract were determined by using gas chromatography–mass spectroscopy (GC–MS). Linoleic acid was found to be major constituent of the petroleum ether extract of D. vulgaris. Conclusion: This study has provided some justification for the folkloric use of the plant.
