First cultivation trial ofPerilla frutescens L. in Egypt

Abstract

Imported seeds of Perilla frutescens L. (cv. Aka‐Shiso and Ao‐Shiso) were propagated and cultivated in Egypt. The growth, herbal yield and volatile oil yield were recorded. The yield of volatile oil, extracted by hydrodistillation, reached 0.17%, 0.01% and 0.16% of fresh weight of leaves, stem and flowers, respectively. The volatile oil of the aerial parts of each variety was analysed by capillary GC–MS. The hydrodistillates of both varieties mainly consist of perillaldehyde, caryophyllene oxide, limonene and caryophyllene, with perillaldehyde as the main constituent (32.9% and 34.2% for Aka‐Shiso and Ao‐Shiso, respectively). Some significant differences in the oil constituents were observed, where caryophyllene oxide reached 23.3% in Ao‐Shiso but accounted for only 6.0% in Aka‐Shiso. The antimicrobial activity for both oils was studied. © 1998 John Wiley & Sons, Ltd.

Chemical composition of seed essential oils from Algerian Nigella sativa extracted by microwave and hydrodistillation

“…The main components in T MD and A MD were p-cymene (28.1% T MD vs. 8.9% T HD and 32.0% A MD vs. 7.2% A HD ) and thymoquinone (10.8% T MD vs. 1.6% T HD and 24.6% A MD vs. 21.8% A HD ). In previous studies, 29,30 results showed that p-cymene is a thymol precursor that by oxidation generates the thymoquinone precursor. The main constituents in T HD and A HD were carvacrol (12.9% T HD vs. 3.0% T MD and 12.9% A HD vs. 6.0% A MD ), thymohydroquinone (6.1% T HD vs. 0.7% T MD and 12.2% A HD vs. 1.1% A MD ), 4-terpineol (0.6% T HD vs. 3.4% T MD and 8.9% A HD vs. 2.0% A MD ) and thymol (1.5% T HD vs. 0.3% T MD and 0.7% A HD vs. 0.3% A MD ).…”

Ethnomedicinal, Phytochemical and Pharmacological Investigations of Perilla frutescens (L.) Britt.

“…Luteolin has been isolated from PFL ethanol extracts and was demonstrated to exert beneficial effects on neuro-inflammatory diseases in a dose-dependent manner (IC 50 = 6.9 μM) through suppressing the expression of inducible nitric oxide synthase (iNOS) in BV-2 microglial cells [43].…”

Rapid analysis of the essential oil components of dried Perilla frutescens (L.) by magnetic nanoparticle-assisted microwave distillation and simultaneous headspace solid-phase microextraction followed by gas chromatography-mass spectrometry

“…Aminefunctionalized magnetite nanoparticles were used as a microwave absorption solid medium, and Perilla frutescens (L.) (Zhishu in Chinese) was used in this study, which has been used in Chinese traditional medicine as a diaphoretic, antipyretic, sedative, an antitussive, and for the treatment of intestinal disorders and allergies. 28,29 The AMN-assisted MD-HS-SPME parameters were studied, and the method precision was also investigated.…”
