Lamiaceae - Science topic

It is known that essential oil yielding plants belong to some specific families such as Lamiaceae, Lauraceae and so on. Is there any specific criteria to identify such oil yielding plants in field without chemical analysis? For survey of such plants?

Just got back from Iran, and there was questions about local eremostachys. Earlie this species originated from Shah Kuh Mnts was identified as molluceloides (=macrophyla). Found the same much further to the West, in Elburs Mnts near Folud Mohale, Semnan Prov. In both places plants grow in similar conditions. Occupy the ridges and upper parts of slopes of the Northern, North-Western and Western orientation at the height of 2000-2300 m. The plants are quite tiny, their height together with the spike no more than 20-25 cm. See picture 1-5 shows the plants themselves and the places of their growth. Much further South, in the vicinity of Reshm, Semnan Prov., I found Eremostachys, which does, at first glance, morphologically not different from the previous one, except for the size (photo 6-10). This is a powerful plant at least half a meter high. Grows at the junction of the slope and valleys and in the bottoms of mountain valleys at an altitude of about 1500 m. In areas where it grows the first plant, is not found the second, and vice versa. In your opinion, are these two similar Eremostachys are different species, or just two different forms of the same species?

I conducted a chemo-informatics study on phytochemicals isolated from Leonotis leonurus; one of the compounds was predicted to pass the drug-like rules set by Lipinski, Veber and Egan making it drug-like but it was predicted to have a low GI absorption profile and non-BBB permeant. Is this possible? If so, why?

As the lamiaceae members contains aroma, Is there any link between the aromatic oil and density of trichome.

Dear Researchers Society, I prepare my master's thesis on the genus Mentha L. (Lamiaceae Lindl.). Could someone suggest me useful articles, publications and websites about representatives of this genus, descriptions of species, their morphometry, a list of confirmed taxa, identification keys and other information that you consider relevant. I thank You in advance.

It has widely open flowers, lanceolate leaves arranged oppositely, calyces are very narrow and long, tubular, clustered together at the top of the stem. It is an ornamental found in Poland. Thanks for any suggestion.

We are trying to analyze the endogenous volatile compounds of Mentha spicata and other Lamiaceae plants through GC-MS. We are using DCM but still the chlorophyll content in the leaf extract is too high. What other organic solvents can be used so that there is no chlorophyll content in the extract and the endogenous volatile components are also secure?

Hello,

Iam working on antioxidant activity of lamiaceae family, i want to study effect of antioxidant on sperm dysfuctioning, motilty, count, due to oxidative stress and regain due to antioxidant supply, please if suggest guideline or protocol for it , where i can carry this experiment.

Thanks.

Hi, my topic is phytochemical and antioxidant properties of selected species of lamiaceae" i have screened samples by dpph method, now i want to do quantitative analysis which method shoild i use

Please help to identify to species this eremostachys. It is from: IRAN, SEMNAN, SHAHRUD AREA, SHAH-KUH MTS., SHAHVAR MT., N36º31', E 54º45', ~2100 m, 15-17.V.2017

This is a question on statistical methods used in DNA research

Lately, many plant species are changing from species, genera, or even families due to studies in molecular makers. For example, teak and gmelina tree species were changed from Verbenaceae to Lamiaceae. The old Bombacopsis quinatum was changed first to Pachira quinata and now to Pochota fendlery. In the case of Orchids, the species of the genera Cattleya, Laelia, Schomburkia, and Sophronitis are suffering continuous changes in the classification of the various species within these genera. How sound are statistical techniques used to ensure these are real differences. What is the sampling method used?

any paper or report about Hybridization, polyploids, ... and new methods. 

This plant grew in wild. It is some 40 cm tall. Flowers minute, could be pink. Leaf blades 20-25 cm long.

It was collected in S Croatia (Split)

Please help to identify to species this Eremostachys. It is from: IRAN, Razavi Khorasan Province, Kuh-e-Binalud Mts., Dorrud v. vicinity N 36º08', E 59º10', ~2000 m, 12-14.V.2017

Dear All,

I am basically looking for an information on the distribution of  Origanum vulgare subsp. glandulosum (Desf.) Ietsw. in North Africa and mediterranean basin.

The upper surface of teak (Tectona grandis) leaves is rough. In bamboos and wheat this is caused by the silica content. It seems this is not the case for teak.

I am researching reproduction of Salvia officinalis, I found some knowledge on Lamiaceae but it's not enough. Do you have any article please share with me.

In some papers Fusarium oxysporum have introduced as a pathogen for lemon balm but without "f.sp." specialty

I want to evaporate an Ajuga methanolic extract until complete dryness. I am almost at the end and I have evaporated most of the methanol at around 300-337 mbar, but I don`t understand why it started to distil also at 25 mbar - such a low pressure? Is it because the residue is thick and it`s more difficult for the methanol to evaporate? I don`t understand the phenomenon. The vegetal material used was dry and I only used methanol for the extraction.

Thank you very much!

I found this Lamiaceae with tiny blue corolla on several occasions in dry river beds ('barrancos') close to habitations in Tenerife, Canary Islands. I believe it is a non-native species, introduced with sewage sludge (along with Solanum lycopersicum, Cucurbita spec., Helianthus annuus, Phalaris canariensis, etc.). I guess it either is a spice or a birdseed impurity.

Thank you in advance for your suggestions.

Best wishes,

Filip
